Report of the Working Party on Lighting and Light-signalling Equipment on its April 2014 session.

21. The representative of Canada, on behalf of the Chair of GRE, reported on the results of the seventy-first session of GRE (for details, see the report of the session ECE/TRANS/WP.29/GRE/71).

24. The World Forum recalled the oral report of the Chair of GRE given during the 163rd session (ECE/TRANS/WP.29/1110, paras. 21-23) and approved the report.

2. GRE considered and adopted the agenda proposed for the seventy-first session (ECE/TRANS/WP.29/GRE/2014/1 and Add.1) as reproduced in GRE-71-01-Rev.3 (including the informal documents distributed during the session).

3. GRE also adopted the running order for the session as proposed in GRE-71-08.

4. The list of informal documents is reproduced in Annex I to the report. The list of GRE informal groups is reproduced in Annex V to the report. GRE took note of the official document submission deadline (GRE-71-20) for the October 2014 session of GRE.

Document prepared by the Secretariat in order to inform GRE about complaints, which do not seem to be isolated, concerning the intensity of LED brake lights in non-emergency braking situations.

42. The secretariat informed GRE about complaints on the intensity of (LED) stop lamps which had been reviewed by the secretariat, GRE Chair and Vice-Chair (GRE-71-02). These complaints mainly related to situations such as “stop and go” or standstill at traffic lights where the driver of the following vehicle experienced discomfort and glare due to the high intensity of stop lights. No one seemed to dispute the need for a high intensity light-signal in case of an emergency.

43. The Chair recalled that GRE, at its sixty-sixth and sixty-seventh sessions, had already discussed a proposal by GTB to allow for reducing the intensity of stop lamps when the vehicle speed was below 20 km/h. Due to lack of consensus, this proposal had been withdrawn at that time. GRE was of the view that no study proved any blinding or glare effect specific to LED stops lamps and that the reported complaints were probably related to discomfort problems in a narrow range of urban traffic conditions and that stop lamps were so far performing very well their most important safety function. Therefore, no further action was foreseen by GRE.

Correction to paragraph 6.2.7.6.1. where the reference should read Annex 13 instead of Annex 12.

16. The secretariat proposed a correction to para. 6.2.7.6.1. of Revision 8 of UN Regulation No. 48 (GRE-71-03). The Chair also proposed the replacement in para. 6.6.7.2. of the incorrect reference to para. 6.22. by para. 6.23. GRE adopted the proposal amended by the Chair and decided to defer the submission of this proposal to WP.29 and AC.1 awaiting the adoption of further corrections that the expert from Italy volunteered to prepare (see para. 17 below).

17. The expert from Italy informed the GRE that he had found a number of errors in Regulation No. 48. GRE invited the expert from Italy to submit a document for the next session (see para. 16 above).

21. The expert from Germany presented GRE-71-25 introducing flashing side marker lamps for vehicles of categories N2, N3, O3 and O4, aimed at informing vulnerable road users about the intention of a heavy goods vehicle to make a turn. The experts from Italy, Netherlands and CLEPA delivered a number of comments, in particular suggesting the extension of this proposal to M2 and M3 buses. The expert from Germany volunteered to submit a revised official document for the next session of GRE.

Correction to the proposal for Supplement 17 to Regulation No. 50 (to introduce the possibility of interdependent lamps for dedicated motorcycle lamps). Annex 1, Paragraph 4., should read: “However, in the case where a device is intended to be installed with its H plane at a mounting height less than 750 mm above the ground, the angle of 15 10° below the horizontal may be reduced to 5°”

57. The expert from IMMA presented ECE/TRANS/WP.29/GRE/2014/7 with a proposal to amend UN Regulation No. 50, as further corrected by GRE-71-04 and GRE-71-12-Rev.1, introducing the possibility of interdependent lamps for dedicated motorcycle lamps. The expert from India also presented GRE-71-30 containing an amendment to this proposal. GRE generally supported the proposal but, given the late submission of GRE-71-30, decided to revisit this issue at its next session on the basis of a revised document ECE/TRANS/WP.29/GRE/2014/7/Rev.1 to be prepared by IMMA.

Proposal from the secretariat to delete the reference to Category 3 and 4 from Annex 1, item 9, of UN R6 since these two categories appear to have been reintroduced by mistake through Amendment 3 to Revision 5 of the regulation.

64. The secretariat proposed editorial changes to Amendment 3 to Revision 5 of UN Regulation No. 6, as contained in GRE-71-05. GRE adopted this proposal and requested the secretariat to take this editorial correction into consideration when issuing Revision 6 to the UN Regulation.

Proposal to insert the IEC cap sheet numbers assigned for the new light categories WT21W, WTY21W, WT21/7W and WTY21/7W.

6. The expert from IEC presented GRE-71-06 with the aim to introduce proper references to the IEC cap sheet numbers, in accordance with IEC Publication 60061, for new categories of light sources WT21W, WTY21W, WT21/7W and WTY21/7W which have been introduced into United Nations (UN) Regulation No. 37. A similar request (GRE-71-07) was also made for new light source category LW2 which had been previously inserted in UN Regulation No. 128.

7. The experts from Germany and UK expressed their concerns that, in the past, GRE had approved the respective amendment proposals without the relevant references (i.e. blanks in square brackets) which were not available at that time and which de facto required the adoption of an additional supplement for inserting the proper reference at a later stage.

8. GRE adopted both proposals and requested the secretariat to submit them to WP.29 and the Administrative Committee of the 1958 Agreement (AC.1) for consideration at their November 2014 sessions as draft Supplement 43 to the 03 series of amendments to UN Regulation No. 37 and draft Supplement 3 to the original series of amendments to UN Regulation No. 128.

Proposal to insert the IEC cap sheet number for the new light category LW2 into the regulation.

6. The expert from IEC presented GRE-71-06 with the aim to introduce proper references to the IEC cap sheet numbers, in accordance with IEC Publication 60061, for new categories of light sources WT21W, WTY21W, WT21/7W and WTY21/7W which have been introduced into United Nations (UN) Regulation No. 37.

Proposal to delete the requirement that the total objective luminous flux of all LED modules producing the principal passing (main low) beam of a headlamp be greater than or equal to 1000 lumens. France argues that the requirement is design-restrictive, unnecessary given the objective criteria for luminous output and photometric grid points of the regulation, and obsolete given improvements in LED technologies.

67. The expert from France introduced GRE-71-09 and GRE-71-10 proposing to delete an unjustified design restrictive requirement of a minimum luminous flux of 1,000 lm for LED’s in UN Regulations Nos. 112 and 123. While several experts supported this proposal, some others pointed out that those alternative criteria should be developed to guarantee a minimum performance of LED light sources. GRE decided to revert to this issue at the next session and requested the secretariat, in cooperation with the expert from France, to re-issue GRE-71-09 and GRE-71-10 as official documents.

Discussion document on tell-tale requirements in Regulation No. 48 versus Regulation No. 121 and consideration of establishing a task force to further discuss the issues involved. Pursuant to discussions at the previous two GRE sessions concerning the use of the term “failure tell-tale” in relation to daytime running lamps and adaptive front lighting systems (AFS) in UN R48 and the potential impact on UN R121 concerning the “location and identification of hand controls, tell-tales and indicators”, the Netherlands proposes the formation of a special task force to study the issues and propose draft amendments for lighting regulations as warranted.

15. The expert from the Netherlands recalled the GRE considerations, at its sixty-ninth and seventieth sessions, of tell-tale requirements and the possible need for aligning UN Regulation No. 48 with relevant requirements contained in UN Regulation No. 121. Given the complexity of the issue, he suggested continuing with more in-depth discussions on these issues in a smaller group of interested experts (GRE-71-11). Following this request, GRE consented to establishing a taskforce on tell-tale requirements, for which the expert from the Netherlands would act as Chair and OICA as secretary. GRE decided to keep this issue on the agenda and requested the task force to report on its findings at the next session of GRE.

Document to correct the original proposal to introduce the possibility of interdependent lamps for dedicated motorcycle lamps by including an omitted diagram and highlighting the marking clause.

Updated document to correct the original proposal to introduce the possibility of interdependent lamps for dedicated motorcycle lamps by including an omitted diagram and highlighting the marking clause.

57. The expert from IMMA presented ECE/TRANS/WP.29/GRE/2014/7 with a proposal to amend UN Regulation No. 50, as further corrected by GRE-71-04 and GRE-71-12-Rev.1, introducing the possibility of interdependent lamps for dedicated motorcycle lamps. The expert from India also presented GRE-71-30 containing an amendment to this proposal. GRE generally supported the proposal but, given the late submission of GRE-71-30, decided to revisit this issue at its next session on the basis of a revised document ECE/TRANS/WP.29/GRE/2014/7/Rev.1 to be prepared by IMMA.

Document GRE/2013/62 concerning electronic light source control gear proposed to introduce requirements to avoid intentional non-approved (voltage) variation of the principal passing beam using halogen light sources and to harmonize them with the operating voltage requirements in UN Regulation No. 48. The objective of this proposal is to restrict the voltage at headlamps equipped with (halogen) filament lamp light sources in order to avoid excessively high or low (semi-) permanent luminous intensity of the headlamp and consequently shorter lifetime of the halogen light source. This submission takes into account the positions presented in documents GRE/2013/44, GRE/2013/62, GRE-70-17, and GRE-70-34.

28. The expert from IEC introduced GRE-71-13 proposing alternatives to ECE/TRANS/WP.29/GRE/2013/62 on electronic light source control gear:

(a) Restricting the voltage range for (halogen) filament light sources, to avoid (semi-)permanent too low or too high luminous intensity of the headlamp and subsequent shorter lifetime of the filament light source and;

(b) Inserting a lower voltage limit and verifying that the headlamp performance, in terms of luminous intensity, under the normal operating conditions of the vehicle’s electrical system is still compliant with the requirements of UN Regulation No. 112.

29. A number of experts delivered remarks on this document. GRE invited other experts to transmit their comments, if any, to IEC and decided to revert to this issue on the basis of a revised document to be prepared by IEC.

After examination of the draft revision of UN Regulation 86 (document GRE/2014/2), the Italian experts believe it necessary to make six further changes, including definition of “textured lens” and clarifications of certain paragraphs.

Status report on efforts to resolve concerns related to automatic headlamp leveling provisions and their impact on visibility and on-coming driver glare.

11. The expert from GTB introduced the results of their studies on visibility and glare (GRE-71-15 and GRE-71-32). The study concentrated on levelling in relation to load and its major objectives were to improve the understanding of different factors that influence visibility and glare and to identify results of the study that might reveal alternatives for automatic static levelling. The expert from OICA recalled their presentations on loading definitions and achievable aiming tolerances (see also GRE-67-27 and GRE-68-20).

12. The expert from Poland introduced a revised proposal ECE/TRANS/WP.29/GRE/2014/11 on initial aiming of dipped-beam headlamps and considering the original 75 +/-25 m visibility distance requirement.

13. GRE was of the view that the study had pointed out that the type of light source and its luminous flux are not the deciding factors in headlamp glare. Instead, the most important factors seem to be the vehicle pitch angle, loading conditions and initial headlamp aim. Therefore, the light source choice (LED) and the light source 2,000 lm criteria in UN Regulation No. 48 were found unnecessarily restrictive and creating barriers to new technologies. Different views were expressed whether automatic levelling should become a requirement for all categories of vehicles and light sources. Operating voltage was also mentioned as an additional factor of glare.

14. GRE invited the experts from Poland, GTB and OICA to submit one coherent proposal for amendments to UN Regulation No. 48 addressing the visibility distance and glare issuto the next GRE session.

Outcome of the first meeting of interested experts to explore ways to reduce the administrative and regulatory burdens associated with the current structure of lighting regulations, including difficulties in transposing UN lighting regulations into local legislation in the EU and Japan. The experts recommend reactivation of the “Horizontal Reference Document” initiative.

36. GRE took note of the outcome of the first session of the Special Interest Group (SIG) which had taken place in Brussels on 12 February 2014 and had been attended by 20 experts (GRE-71-16). In particular, SIG was of the view that priority should be given to reducing the administrative burden presented by the numerous collective amendments. To achieve this, SIG proposed to reactivate the GRE Horizontal Reference Document (HRD) Informal Group and to update its Terms of Reference (ToR).

37. On behalf of SIG, the expert from EC presented draft ToR of a new informal working group (IWG) (GRE-71-22) and stated that EC would be prepared to act as Co-Chair of IWG. Regarding the position of Chair, he suggested that an EU member State or another Contracting Party assume this role. Before IWG becomes operational, SIG would continue its activities. In this respect, the expert from EC informed GRE that the second meeting of SIG would take place in Brussels during the week 9-13 June 2014.

38. GRE had a first exchange of views on the proposed ToR with a particular focus on paras. 2, 3 and 4 of GRE-71-22.

39. GRE addressed the issue of the legal implications of placing the common requirements into a horizontal reference document, such as R.E.3 managed by WP.29. The expert from EC and the secretariat pointed out that, if needed, they would seek legal advice from, respectively, EU and United Nations legal services. The secretariat informed GRE that R.E.3 had proved to be very instrumental for all UN Regulations, in particular, with regard to common definitions. In this context, the secretariat also drew the attention of GRE to the work undertaken by the secretariat to harmonize the definitions in lighting and light-signalling UN Regulations (GRE-71-23). GRE requested the SIG to consider this document and consolidate harmonized definitions into the horizontal document.

40. The Chair invited experts to consider the underlying issues, in particular the draft ToR of IWG in GRE-71-22 to be discussed at the next SIG session, and to report back to GRE at its next session. He also suggested that the newly proposed IWG take into due consideration ECE/TRANS/WP.29/GRE/2008/32, GRE-59-01, GRE 63-27, GRE-66-13 and GRE-66-14.

GTB white paper on priorities and objectives for the simplification of lighting regulations, especially regarding reduction of the current burdens associated with the necessity of collective amendments in the development of these regulations and the longer-term difficulties to be overcome in restructuring these regulations and their legal framework.

33. Having pointing out that the European Union (EU) refers to UN Regulations in its legislation, the expert from EC informed GRE about three concerns that EC and some EU member States have with regard to the GRE scope of activities:

a) A large number of GRE-related UN Regulations (forty-one) and their constant updating are a serious burden for the efficient management of the system, both for the United Nations and EU. Consequently, around one third of all documents under the WP.29 umbrella are from GRE. A lot of resources are required for their official translation into various languages, and there is a considerable backlog in this area. Thus, according to the expert from EC, the incurred costs should be minimized by simplifying and streamlining the documentation originating from GRE;

b) Some UN Regulations prepared and/or amended by GRE in the past were rather descriptive and not enough performance based. According to the expert from EC, descriptive provisions could, in some cases, distort the market competition and impede new technologies and innovations;

c) Too prescriptive and descriptive approach could make UN Regulations less attractive to countries outside the ECE region. According to the expert from EC, probably for this reason two years ago Japan had not adhered to UN Regulation No. 128. Moreover, the United States of America, who has only one regulation related to lighting and light signalling, would oppose developing multitude UN GTRs in this area, given the present number of UN Regulations on this subject. As an alternative example, he mentioned the area of fuel efficiency and emissions where there were fewer documents, that were not too prescriptive, and where the Asian countries supported a new UN GTR which had recently been adopted.

34. The expert from EC was also confident that GRE had all the necessary competencies to address these concerns and urged GRE to do so without delay.

35. The expert from GTB contributed to the discussion by presenting GRE-71-17 and GRE-71-24 containing some ideas on simplification of lighting and light-signalling UN Regulations. According to him, these UN Regulations are at present a mix of regulatory (legal) and technical aspects which should be separated in the future. A solution could be found in creating a three-level documentation structure, as proposed in GRE-71-24, where provisions common for different UN Regulations would be put in a single document similar to Consolidated Resolution R.E.3.

Proposal to extend the modifications that introduced provisions for interdependent direction indicator lamps in the 06 series of amendments to UN R48 to the 04 and 05 series in order to avoid an unjustified design restriction for approvals under the earlier versions of the regulation.

19. The expert from France introduced GRE-71-18 proposing two amendments to series 04 and 05 series of amendments to UN Regulation No. 48:

(a) The first amendment introduced interdependent lamp systems in para. 5.18.4. (b) and was based on ECE/TRANS/WP.29/2014/21 adopted during March 2014 session as a new supplement for 06 series of amendments to UN Regulation No. 48.

(b) The second amendment suggested that the speed limit in paragraph 6.22.7.4.3 was reduced from 70 to 60 km/h and the requirements of paragraph 6.22.7.4.3(a) was amended to indicate a clear alternative to either detect the motorway conditions with sensors or only activate the E mode above a speed of 110 km/h. The objective of this amendment proposal was to improve the performance of the system by avoiding unnecessary on-off activation of the motorway light.

20. GRE adopted proposal (a) above and requested the secretariat to transmit it to WP.29 and AC.1 for consideration at their November 2014 sessions as draft supplement to the 04 and 05 series of amendments to UN Regulation No. 48. GRE decided to come back to proposal (b) at its next session.

17. GRE noted that the expert from France had withdrawn its proposal to modify the speed threshold in paragraph 6.22.7.4.3. (GRE-71-18).

Request to extend the work of the AVLI group in order to develop amendments that would apply UN R86 to agricultural trailers and towed machinery.

46. The expert from the Netherlands, chairing the informal Group on Agricultural Vehicle Lighting Installation (AVLI), introduced ECE/TRANS/GRE/2014/2 containing the AVLI proposals to update and revise UN Regulation No. 86 with a view to improving the visibility of agricultural vehicles. In particular, the proposals provided for updating the present UN Regulation No. 86 provisions ; optional installation of “innovative” lamps (e.g. daytime running lamps, cornering lamps etc.); aligning, where appropriate, the requirements with the corresponding provisions of UN Regulation No. 48.

47. To ensure an earlier revision of UN Regulation No. 86, the Chair of AVLI suggested splitting its work into two phases and, to this end, proposed to revise the ToR and rules of procedures of the Group (GRE-71-19). According to the revised ToR, while the first phase should focus on updating the present UN Regulation No. 86 in order to improve the visibility of existing agricultural tractors, the second phase could address extending the scope of the present UN Regulation No. 86 to new categories of vehicles such as agricultural trailers and towed machinery.

48. GRE stressed the urgent need for modification of UN Regulation No. 86, which had not been updated for fifteen years, and agreed with the proposed two-phase approach. GRE adopted the revised terms of reference and the rules of procedures of AVLI, reproduced in Annex IV to the report. To avoid the need for transitional provisions, GRE decided to remove the square brackets in paragraphs 6.4.1., 6.10.1. and 6.19.1. of ECE/TRANS/GRE/2014/2, thus making reversing lamps, rear fog-lamps and daytime running lamps optional. GRE requested AVLI to submit to its next session, a revised document ECE/TRANS/WP.29/GRE/2014/2/Rev.1 which would address comments made during the discussion, in particular by the expert from Italy (GRE-71-14).

49. GRE noted that, in order to introduce new categories of vehicles into UN Regulation No. 86, the Consolidated Resolution (R.E.3) should be amended accordingly to include such categories. In this context, the expert from IMMA also pointed out differences between the definitions of the L categories of vehicles in R.E.3 and in the EU legislation To inform WP.29 and other GR’s about these intentions, GRE mandated its Chair to orally raise these issues at the June 2014 session of WP.29 as well as requested the secretariat to prepare a proposal as soon as possible to ensure their early distribution to other GR’s.

2. GRE considered and adopted the agenda proposed for the seventy-first session (ECE/TRANS/WP.29/GRE/2014/1 and Add.1) as reproduced in GRE-71-01-Rev.3 (including the informal documents distributed during the session).

3. GRE also adopted the running order for the session as proposed in GRE-71-08.

4. The list of informal documents is reproduced in Annex I to the report. The list of GRE informal groups is reproduced in Annex V to the report. GRE took note of the official document submission deadline (GRE-71-20) for the October 2014 session of GRE.

WP.29 secretariat update on the development and implementation of the DETA system.

24. The secretariat delivered a presentation (GRE-71-21) outlining the progress made in establishing the Database for the Exchange of Type Approval documentation (DETA) which, inter alia, would allow the simplification of the approval markings by implementing the “unique identifier” (UI) function. GRE noted that, until all Contracting Parties adopt the DETA marking scheme, the use of UI may remain optional, unless stated otherwise in a given UN Regulation. GRE agreed to resume consideration of this item at its October 2014 session.

24. GRE recalled the presentation on simplifying the approval markings by implementing the “unique identifier” function in the envisaged Database for the Exchange of Type Approval documentation (GRE-71-21) and requested IWG SLR to pursue this issue.

Draft scope and objectives for the proposed program to restructure and simplify UN lighting and light-signaling equipment regulations.

36. GRE took note of the outcome of the first session of the Special Interest Group (SIG) which had taken place in Brussels on 12 February 2014 and had been attended by 20 experts (GRE-71-16). In particular, SIG was of the view that priority should be given to reducing the administrative burden presented by the numerous collective amendments. To achieve this, SIG proposed to reactivate the GRE Horizontal Reference Document (HRD) Informal Group and to update its Terms of Reference (ToR).

37. On behalf of SIG, the expert from EC presented draft ToR of a new informal working group (IWG) (GRE-71-22) and stated that EC would be prepared to act as Co-Chair of IWG.

GRE requested the SIG to consider this document and consolidate harmonized definitions into the horizontal document.

40. The Chair invited experts to consider the underlying issues, in particular the draft ToR of IWG in GRE-71-22 to be discussed at the next SIG session, and to report back to GRE at its next session. He also suggested that the newly proposed IWG take into due consideration ECE/TRANS/WP.29/GRE/2008/32, GRE-59-01, GRE 63-27, GRE-66-13 and GRE-66-14.

Concordance of technical definitions used across UN lighting regulations.

21. GRE requested IWG SLR to consider GRE-71-23 and to consolidate into a horizontal document, harmonized definitions in lighting and light-signalling Regulations. For the same purpose, GRE referred to IWG SLR collective proposals, such as compliance obligations with installation requirements, definition of “type” with regard to the manufacturer and trade names/marks and provisions for the conformity of production, including those that had been referred back by WP.29 (ECE/TRANS/WP.29/GRE/2013/55/Rev.1, ECE/TRANS/WP.29/2013/68, ECE/TRANS/ WP.29/2013/69, ECE/TRANS/WP.29/2013/71, ECE/TRANS/WP.29/2013/72, ECE/ TRANS/WP.29/2013/76, ECE/TRANS/WP.29/2013/79, ECE/TRANS/WP.29/2013/83, ECE/TRANS/WP.29/2013/84, ECE/TRANS/WP.29/2013/85, ECE/TRANS/WP.29/ 2013/86, ECE/TRANS/WP.29/2013/87, ECE/TRANS/WP.29/2013/88, ECE/TRANS/ WP.29/2013/89, ECE/TRANS/WP.29/2013/94, ECE/TRANS/WP.29/GRE/2014/3).

A lot of resources are required for their official translation into various languages, and there is a considerable backlog in this area. Thus, according to the expert from EC, the incurred costs should be minimized by simplifying and streamlining the documentation originating from GRE;

b) Some UN Regulations prepared and/or amended by GRE in the past were rather descriptive and not enough performance based. According to the expert from EC, descriptive provisions could, in some cases, distort the market competition and impede new technologies and innovations;

c) Too prescriptive and descriptive approach could make UN Regulations less attractive to countries outside the ECE region. According to the expert from EC, probably for this reason two years ago Japan had not adhered to UN Regulation No. 128. Moreover, the United States of America, who has only one regulation related to lighting and light signalling, would oppose developing multitude UN GTRs in this area, given the present number of UN Regulations on this subject. As an alternative example, he mentioned the area of fuel efficiency and emissions where there were fewer documents, that were not too prescriptive, and where the Asian countries supported a new UN GTR which had recently been adopted.

34. The expert from EC was also confident that GRE had all the necessary competencies to address these concerns and urged GRE to do so without delay.

35. The expert from GTB contributed to the discussion by presenting GRE-71-17 and GRE-71-24 containing some ideas on simplification of lighting and light-signalling UN Regulations. According to him, these UN Regulations are at present a mix of regulatory (legal) and technical aspects which should be separated in the future. A solution could be found in creating a three-level documentation structure, as proposed in GRE-71-24, where provisions common for different UN Regulations would be put in a single document similar to Consolidated Resolution R.E.3.

Proposal to introduce flashing side marker lamps for vehicles of categories N₂, N₃, O₃ and O₄. The objective of this provision is to improve the safety of vulnerable road users by better informing them about the intention of a heavy goods vehicle to make a turn. Germany believes this to be a simple measure that will improve the safety level especially for cyclists and pedestrians located in the blind spot area of a heavy goods vehicle.

Text originally prepared by Belgium to propose amendments to Regulation No. 107 to align the additional safety prescriptions for trolleybuses (Annex 12) with the corresponding electrical standards (see document GRSG/2013/16). During discussion in the October 2013 session of GRSG, some Contracting Parties felt that the prescriptions for electromagnetic compatibility of trolleybuses belong in Regulation No. 10. So these prescriptions are taken out of the amended proposal (ECE/TRANS/WP.29/GRSG/2014/19) and are proposed here for consideration by GRE for further action.

65. The expert from Belgium introduced GRE-71-26 proposing amendments to UN Regulation No. 10 with regard to electromagnetic compatibility of trolleybuses, with a view to aligning the additional safety prescriptions for trolleybuses (Annex 12 to UN Regulation No. 107) with the corresponding electrical standards (see ECE/TRANS/WP.29/GRSG/2013/16). GRE invited the expert from Belgium to re-submit his contribution as official document for consideration at the next session.

Document GRE/2014/13 proposes to ensure that the introduction of the new class F marking materials does not conflict with the mandatory requirements for existing class C materials. The addition of Class F brings markings required under certain countries’ national legislation within the UN regulatory system. However, Japan actually prohibits the use of white retro-reflective markings on the rear of vehicles. Therefore, Japan proposes the addition of a footnote confirming the right of Contracting Parties to prohibit the use of Class F markings under national legislation.

63. The expert from Japan introduced GRE-71-27 and GRE-71-28, proposing to insert a new footnote to read “The Contracting Parties applying this UN Regulation may prohibit the use of Retro-Reflecting materials approved as Class F on the basis of national regulations.” GRE concluded that it is obvious even without such a footnote that the Contracting Parties may prohibit the use of such materials. As a result of discussion, these informal documents were withdrawn.

Document GRE/2013/65/Rev.1 proposes a new class F of marking materials designed with chevron type pattern to be applied to special utility vehicles or trailers not ordinarily covered by standard contour marking materials. The proposal also attempts to harmonize a number of national requirements. Japan, however, prohibits white retro-reflecting materials at the rear of vehicles for safety reasons. Therefore, Japan proposes to clarify that the approval of Class F retro-reflective markings is dependent upon their definition within national regulatory requirements.

63. The expert from Japan introduced GRE-71-27 and GRE-71-28, proposing to insert a new footnote to read “The Contracting Parties applying this UN Regulation may prohibit the use of Retro-Reflecting materials approved as Class F on the basis of national regulations.” GRE concluded that it is obvious even without such a footnote that the Contracting Parties may prohibit the use of such materials. As a result of discussion, these informal documents were withdrawn.

Presently, UN R48 requires that reverse lights be switched off when cornering lights are switched off. OICA argues that the simultaneous lightning of both cornering lamps for slow maneuvers in forward motion (e.g., while parking a vehicle) can increase safety by improved illumination of surroundings. Therefore, OICA proposes that cornering lights be allowed to remain on as long as the vehicle speed does not exceed 10 km/h.

22. The expert from OICA introduced GRE-71-29 proposing the simultaneous lightning of both cornering lamps for slow manoeuvres in forward motion, in order to increase safety. GRE requested the secretariat to distribute this proposal at the next session with an official symbol.

In document GRE/2014/7, IMMA proposed to introduce the possibility of interdependent lamps for dedicated motorcycle lamps as Supplement 17 to Regulation No. 50. The concern was that the rear trunk lid commonly used for four-wheeled vehicles may be adapted for future scooter type motorcycles to secure the storage space for helmet, etc. Current lamp requirements impose design constraints that may hamper the proper development of such storage features. In this document, India proposes to clarify that the installation height of the device must be less than or equal to 750 mm.

57. The expert from IMMA presented ECE/TRANS/WP.29/GRE/2014/7 with a proposal to amend UN Regulation No. 50, as further corrected by GRE-71-04 and GRE-71-12-Rev.1, introducing the possibility of interdependent lamps for dedicated motorcycle lamps. The expert from India also presented GRE-71-30 containing an amendment to this proposal. GRE generally supported the proposal but, given the late submission of GRE-71-30, decided to revisit this issue at its next session on the basis of a revised document ECE/TRANS/WP.29/GRE/2014/7/Rev.1 to be prepared by IMMA.

In document GRE/2014/9, IMMA proposed the use of different brake lamp activation methods and the introduction of high-mounted stop lamps to improve the conspicuity of “powered two-wheelers” under Regulation No. 53. In this document, India offers a number of editorial recommendations.

11. The expert from GTB introduced the results of their studies on visibility and glare (GRE-71-15 and GRE-71-32). The study concentrated on levelling in relation to load and its major objectives were to improve the understanding of different factors that influence visibility and glare and to identify results of the study that might reveal alternatives for automatic static levelling. The expert from OICA recalled their presentations on loading definitions and achievable aiming tolerances (see also GRE-67-27 and GRE-68-20).

12. The expert from Poland introduced a revised proposal ECE/TRANS/WP.29/GRE/2014/11 on initial aiming of dipped-beam headlamps and considering the original 75 +/-25 m visibility distance requirement.

13. GRE was of the view that the study had pointed out that the type of light source and its luminous flux are not the deciding factors in headlamp glare. Instead, the most important factors seem to be the vehicle pitch angle, loading conditions and initial headlamp aim. Therefore, the light source choice (LED) and the light source 2,000 lm criteria in UN Regulation No. 48 were found unnecessarily restrictive and creating barriers to new technologies. Different views were expressed whether automatic levelling should become a requirement for all categories of vehicles and light sources. Operating voltage was also mentioned as an additional factor of glare.

14. GRE invited the experts from Poland, GTB and OICA to submit one coherent proposal for amendments to UN Regulation No. 48 addressing the visibility distance and glare issuto the next GRE session.

9. Taking into account the recent GTB study (GRE-71-32), the expert from France proposed to delete a design restrictive requirement for an automatic levelling device for all headlamps with LED light sources, irrespective of their luminous flux (ECE/TRANS/WP.29/GRE/2014/34). GRE agreed that this proposal should be tackled at the next session, in conjunction with the GTB proposals on visibility and glare issues (see para. 14 below).

14. The expert from GTB recalled the outcome of the GTB study on visibility and glare (GRE-71-32) and presented a first draft of amendments to Regulation No. 48 addressing the visibility distance and glare issues (GRE-72-07). This proposal received comments by the expert from Poland (GRE-72-23-Rev.1). Various experts generally agreed that the current requirement for automatic levelling in Regulation No. 48 (2,000 lm luminous flux of the light source) should be replaced by other deciding factors for headlamp glare, such as the vehicle pitch angle, loading conditions and initial headlamp aiming. However, no consensus was reached on exact replacement criteria. The expert from UK suggested that an informal group be established to speed up the finalization of the amendment proposal. The experts from France, Germany, Italy and the Netherlands were of the view that GTB should be tasked to submit a concrete proposal to the next session of GRE. GRE invited GTB, OICA and interested Contracting Parties to organize a meeting with the aim to elaborate a revised proposal. The experts from France, Germany, Italy, Netherlands, Poland and UK expressed their interest in participating in this meeting.

69. The expert from GTB presented a status report of the GTB Working Group activities (GRE-71-33, GRE-71-34, GRE-71-35 and GRE-71-36).

69. The expert from GTB presented a status report of the GTB Working Group activities (GRE-71-33, GRE-71-34, GRE-71-35 and GRE-71-36).

69. The expert from GTB presented a status report of the GTB Working Group activities (GRE-71-33, GRE-71-34, GRE-71-35 and GRE-71-36).

Brief presentation raising question over the necessity to have triangular reflectors on the rear of large trailers and seeking greater flexibility in such rear reflectors.

69. The expert from GTB presented a status report of the GTB Working Group activities (GRE-71-33, GRE-71-34, GRE-71-35 and GRE-71-36).

Text prepared by Italy to delete all obsolete references in Regulations Nos. 53 and 74 in order to avoid confusion and possible incorrect application of the requirements containing these references. The deletions cover references to Regulations Nos. 1, 8, 20, 56, 57, 72, 76 and 82. These regulations have all been “frozen” (i.e., they do not apply to new type approvals) and their functions have been taken over by Regulations Nos. 112 and 113.

26. The expert from Italy introduced ECE/TRANS/WP.29/GRE/2013/43/Rev.1 proposing to delete obsolete references in UN Regulations Nos. 53 and 74. The proposal received some comments. The expert from Italy volunteered to provide a revised proposal to GRE at its October 2014 session.

27. The expert from Germany proposed the deletion of the reference to Class B headlamps. Several delegations pointed out that the deletion of Class B headlamps could entail problems for some markets and that transitional provisions would need to be foreseen. GRE agreed to address this issue at its next session on the basis of a written proposal, which the expert from Germany volunteered to prepare.

Proposal to reference the compliance requirements for installation contained in Regulations Nos. 48, 53, 72 and 86 into the Regulations 3, 4, 6, 7, 19, 23, 38, 50, 77, 87, 91, 98, 104, 112, 113, 119 and 123. This proposal is a revised version of document GRE/2013/55 discussed during the October 2013 GRE session.

30. Based on an updated proposal tabled by the expert from Italy (ECE/TRANS/WP.29/GRE/2013/55/Rev.1), GRE resumed consideration of the insertion of compliance obligations with installation requirements, at the time of type approval of lighting components, according to the component UN Regulations. While several experts supported the proposal, some others were of the view that the underlying issue might go beyond the competence of GRE and that WP.29 should be asked for guidance. The Chair suggested clarifying and possibly rephrasing the wording “UN Regulations … and their series of amendments in force at the time of application for type approval”. GRE agreed to continue this discussion at the next session and decided that this proposal would become part of a horizontal document collecting common provisions of UN lighting and light-signalling Regulations (see agenda item 6 below).

21. GRE requested IWG SLR to consider GRE-71-23 and to consolidate into a horizontal document, harmonized definitions in lighting and light-signalling Regulations. For the same purpose, GRE referred to IWG SLR collective proposals, such as compliance obligations with installation requirements, definition of “type” with regard to the manufacturer and trade names/marks and provisions for the conformity of production, including those that had been referred back by WP.29 (ECE/TRANS/WP.29/GRE/2013/55/Rev.1, ECE/TRANS/WP.29/2013/68, ECE/TRANS/ WP.29/2013/69, ECE/TRANS/WP.29/2013/71, ECE/TRANS/WP.29/2013/72, ECE/ TRANS/WP.29/2013/76, ECE/TRANS/WP.29/2013/79, ECE/TRANS/WP.29/2013/83, ECE/TRANS/WP.29/2013/84, ECE/TRANS/WP.29/2013/85, ECE/TRANS/WP.29/ 2013/86, ECE/TRANS/WP.29/2013/87, ECE/TRANS/WP.29/2013/88, ECE/TRANS/ WP.29/2013/89, ECE/TRANS/WP.29/2013/94, ECE/TRANS/WP.29/GRE/2014/3).

10. GRE reviewed and unanimously adopted the pending amendment proposals so as to consolidate the existing Regulations before they are frozen and superseded by three new Regulations that are in drafting:

• ECE/TRANS/WP.29/2013/68,
• ECE/TRANS/WP.29/ 2013/69,

This proposal introduces new class 5 devices made solely of retro-reflective plates with chevron type pattern to be applied to special utility vehicles or trailers not regularly covered by standard rear marking plates. The amendment also seeks to harmonize the text to cover various national requirements.

61. The expert from CLEPA presented revised proposals ECE/TRANS/WP.29/GRE/2013/64/Rev.1 and ECE/TRANS/WP.29/GRE/2013/65/Rev.1, introducing requirements for a new class 5 of devices into UN Regulation No. 70 and requirements and for a new class F of devices into UN Regulation No. 104. GRE adopted this proposal and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2014 sessions as a new Supplement to the 01 series of amendments to UN Regulation No. 70 and as a new Supplement to the original text of UN Regulation No. 104.

This proposal introduces new class F marking materials designed with chevron type pattern to be applied to special utility vehicles or trailers not ordinarily covered by standard contour marking materials. The proposal also attempts to harmonize a number of national requirements.

Text prepared by the Informal Group on “Agricultural Vehicles Lighting Installation” (AVLI) to update and revise Regulation No. 86.

46. The expert from the Netherlands, chairing the informal Group on Agricultural Vehicle Lighting Installation (AVLI), introduced ECE/TRANS/GRE/2014/2 containing the AVLI proposals to update and revise UN Regulation No. 86 with a view to improving the visibility of agricultural vehicles. In particular, the proposals provided for updating the present UN Regulation No. 86 provisions ; optional installation of “innovative” lamps (e.g. daytime running lamps, cornering lamps etc.); aligning, where appropriate, the requirements with the corresponding provisions of UN Regulation No. 48.

47. To ensure an earlier revision of UN Regulation No. 86, the Chair of AVLI suggested splitting its work into two phases and, to this end, proposed to revise the ToR and rules of procedures of the Group (GRE-71-19). According to the revised ToR, while the first phase should focus on updating the present UN Regulation No. 86 in order to improve the visibility of existing agricultural tractors, the second phase could address extending the scope of the present UN Regulation No. 86 to new categories of vehicles such as agricultural trailers and towed machinery.

48. GRE stressed the urgent need for modification of UN Regulation No. 86, which had not been updated for fifteen years, and agreed with the proposed two-phase approach. GRE adopted the revised terms of reference and the rules of procedures of AVLI, reproduced in Annex IV to the report. To avoid the need for transitional provisions, GRE decided to remove the square brackets in paragraphs 6.4.1., 6.10.1. and 6.19.1. of ECE/TRANS/GRE/2014/2, thus making reversing lamps, rear fog-lamps and daytime running lamps optional. GRE requested AVLI to submit to its next session, a revised document ECE/TRANS/WP.29/GRE/2014/2/Rev.1 which would address comments made during the discussion, in particular by the expert from Italy (GRE-71-14).

49. GRE noted that, in order to introduce new categories of vehicles into UN Regulation No. 86, the Consolidated Resolution (R.E.3) should be amended accordingly to include such categories. In this context, the expert from IMMA also pointed out differences between the definitions of the L categories of vehicles in R.E.3 and in the EU legislation To inform WP.29 and other GR’s about these intentions, GRE mandated its Chair to orally raise these issues at the June 2014 session of WP.29 as well as requested the secretariat to prepare a proposal as soon as possible to ensure their early distribution to other GR’s.

Text prepared by the International Automotive Lighting and Light Signalling Expert Group (GTB) to clarify the definition of “type”, with regard to manufacturer, trade names and marks and to introduce editorial improvements to the requirements for markings.

Although documents GRE/2013/45 and GRE-70-02 were adopted by GRE at its last (70th) session, this proposal consolidates the amendments and offers editorial improvements to the provisions concerning markings in Regulations Nos. 19, 23, 38, 65 and 119. These editorial improvements aim to clarify that the devices, and not only the samples, shall bear the trade name or mark and align the requirements with the other correctly worded regulations to avoid misunderstanding.

31. The expert from GTB presented ECE/TRANS/WP.29/2014/3 clarifying the definition of “type” with regard to manufacturer, trade names and marks and to introduce editorial improvements to the requirements for markings. This document superseded ECE/TRANS/WP.29/GRE/2013/45 and GRE-70-02 adopted by GRE at its seventieth session. Various experts identified a number of issues which would require further consideration and clarification. GRE agreed to continue this discussion at the next session and suggested that ECE/TRANS/WP.29/2014/3 become part of a horizontal document collecting common provisions of UN lighting and light-signalling Regulations (see agenda item 6 below).

10. GRE reviewed and unanimously adopted the pending amendment proposals so as to consolidate the existing Regulations before they are frozen and superseded by three new Regulations that are in drafting:

• ECE/TRANS/WP.29/2013/68,
• ECE/TRANS/WP.29/ 2013/69,
• ECE/TRANS/WP.29/2013/71,
• ECE/TRANS/WP.29/2013/72,
• ECE/TRANS/ WP.29/2013/75¹,

Text prepared by the International Automotive Lighting and Light Signalling Expert Group (GTB) to amend the requirements relating to failure indication by removing the differentiation between filament and LED light sources. (Currently the provisions in UN Regulation No. 6 treat the failure of a lamp equipped with filament light sources differently to one equipped with LED. Similar requirements in UN Regulation No. 7 do not include this differentiation.)

56. The expert from GTB introduced ECE/TRANS/WP.29/GRE/2014/4 proposing to amend the requirements of failure indication by removing the differentiation between filament and LED light sources. GRE adopted this proposal and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2014 sessions as draft Supplement 26 to the 01 Series of UN Regulation No. 6.

The text reproduced below was prepared by the expert from the International Automotive Lighting and Light Signalling Expert Group (GTB) to amend the requirements to clarify the “n-1 rule” provisions in relation to an interdependent lamp system. This document has been withdrawn from consideration.

41. GRE noted that the expert from GTB had withdrawn its document ECE/TRANS/WP.29/GRE/2014/5 amending the requirements to clarify the “n-1 rule” provisions in relation to an interdependent lamp system.

Text prepared by the International Automotive Lighting and Light Signalling Expert Group (GTB) to clarify the definitions and requirements associated with the installation of “single lamps”, “lamps marked D” and “Interdependent lamps”.

10. The expert from GTB introduced ECE/TRANS/WP.29/GRE/2014/6 to clarify the definitions and requirements associated with the installation of “single lamps”, “lamps marked D” and “interdependent lamps”. GRE adopted this proposal and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2014 sessions as draft supplements to the 04, 05 and 06 series of amendments to UN Regulation No. 48.

Text prepared by the International Motorcycle Manufacturers Association (IMMA) to introduce the possibility of interdependent lamps for dedicated motorcycle lamps. The proposal reflects recent amendments of Regulations Nos. 6 and 7 and meets the visibility angle requirements of Regulations Nos. 50 and 53. The concern is that the rear trunk lid commonly used for four-wheeled vehicles may be adapted for future scooter type motorcycles to secure the storage space for helmet, etc. Current lamp requirements impose design constraints that may hamper the proper development of such storage features.

57. The expert from IMMA presented ECE/TRANS/WP.29/GRE/2014/7 with a proposal to amend UN Regulation No. 50, as further corrected by GRE-71-04 and GRE-71-12-Rev.1, introducing the possibility of interdependent lamps for dedicated motorcycle lamps. The expert from India also presented GRE-71-30 containing an amendment to this proposal. GRE generally supported the proposal but, given the late submission of GRE-71-30, decided to revisit this issue at its next session on the basis of a revised document ECE/TRANS/WP.29/GRE/2014/7/Rev.1 to be prepared by IMMA.

Text prepared by the expert from the International Motorcycle Manufacturers Association (IMMA) to introduce the possibility of installing interdependent lamps for L3 category vehicles. Also, the amendment reflects the recent amendments to Regulation No. 48, Supplement 2 to its 06 series of amendments and further includes some editorial corrections of current Regulation No. 53 texts. The concern is that the rear trunk lid commonly used for four-wheeled vehicles may be adapted for future scooter type motorcycles to secure the storage space for helmet, etc. Current lamp requirements impose design constraints that may hamper the proper development of such storage features.

58. The expert from IMMA proposed ECE/TRANS/WP.29/GRE/2014/8 to introduce the possibility of installing interdependent lamps for L3 category vehicles in UN Regulation No. 53, together with additional editorial corrections. GRE felt that these amendment proposals should be aligned with the proposed amendments to UN Regulation No. 48 (agenda item 4 (a)) and decided to revert to this issue at its next session on the basis of a revised document to be prepared by IMMA.

Text submitted by the International Motorcycle Manufacturers Association (IMMA) to allow for the use of different brake lamp activation methods for Powered Two Wheelers (PTWs). This amendment also introduces the concept of a high-mounted stop lamp to PTWs to improve the conspicuity of the vehicles during stopping.

59. The expert from IMMA introduced ECE/TRANS/WP.29/GRE/2014/9 with a proposal for amendments to UN Regulation No. 53 to allow for the use of different brake lamp activation methods for Powered Two Wheelers (PTWs) as well as to introduce the concept of a high-mounted stop lamp to PTWs to improve the conspicuity of the vehicles during stopping. GRE adopted this proposal, as amended by Annex II to this report and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2014 sessions as a new Supplement to the 01 series of amendments to UN Regulation No. 53.

Text prepared by the International Motorcycle Manufacturers Association (IMMA) to correct typographical errors introduced during previous amendment to the regulation (ECE/TRANS/WP.29/2012/83). The initial changes were already in Revision 2 of UN Regulation No. 113.

60. The expert from IMMA presented ECE/TRANS/WP.29/GRE/2014/10 with a proposal to correct typographical errors introduced during the previous amendment to UN Regulation No. 113 (ECE/TRANS/WP.29/2012/83). GRE adopted this proposal as a new Supplement to the 01 series of amendments to UN Regulation No. 113 and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2014 sessions.

Text prepared by Poland to introduce an alternative set of performance-based requirements for the initial aiming of dipped-beam headlamps and allowing removing the artificial 2,000 lm borderline and Light Emitting Diode (LED) automatic levelling.

12. The expert from Poland introduced a revised proposal ECE/TRANS/WP.29/GRE/2014/11 on initial aiming of dipped-beam headlamps and considering the original 75 +/-25 m visibility distance requirement.

13. GRE was of the view that the study had pointed out that the type of light source and its luminous flux are not the deciding factors in headlamp glare. Instead, the most important factors seem to be the vehicle pitch angle, loading conditions and initial headlamp aim. Therefore, the light source choice (LED) and the light source 2,000 lm criteria in UN Regulation No. 48 were found unnecessarily restrictive and creating barriers to new technologies. Different views were expressed whether automatic levelling should become a requirement for all categories of vehicles and light sources. Operating voltage was also mentioned as an additional factor of glare.

14. GRE invited the experts from Poland, GTB and OICA to submit one coherent proposal for amendments to UN Regulation No. 48 addressing the visibility distance and glare issuto the next GRE session.

Text prepared by Japan and Finland to introduce provisions for registration plates that differ in size from the standard EU plates.

55. The experts from Finland and Japan presented ECE/TRANS/GRE/2014/12 amending UN Regulation No. 4 (Rear registration plate lamps) for the purposes of IVWTA and introducing provisions for illuminating registration plates of five different sizes (categories) which are currently used around the world. When applying for the first approval or at a later stage, the applicant should indicate the category(ies) which the device is intended to illuminate. GRE adopted the proposal and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2014 sessions as draft Supplement 18 to UN Regulation No. 4.

Proposal to ensure that the introduction of the new class F marking materials does not conflict with the mandatory requirements for existing class C materials. Class F markings are designed with alternate stripe pattern to be applied to special utility vehicles or trailers not regularly covered by standard contour marking materials requires amending the definitions.

62. The expert from CLEPA also proposed ECE/TRANS/WP.29/GRE/2014/13 introducing a new class F of retro-reflecting materials into UN Regulation No. 48, to be applied to special utility vehicles or trailers not regularly covered by standard contour marking materials. GRE adopted this proposal, as amended by Annex III to this report and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2014 sessions as a new Supplement for the 04, 05 and 06 series of amendments to UN Regulation No. 48.
