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.

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the intensity of stop lamps when the vehicle speed was below 20 km/h. Due to lack of consensus, this proposal had been withdrawn at that time.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.

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.

12. The expert from Germany presented a revised proposal to require side marker lamps to flash together with direction indicators on heavy goods vehicles and buses (ECE/TRANS/WP.29/GRE/2014/33, GRE-72-22) as well as additional transitional provisions (GRE-72-05 and GRE-72-06). Following an in-depth discussion, GRE adopted this proposal as contained in Annex VI to the report and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their March 2015 sessions as draft Supplement 5 to the 06 series of amendments to Regulation No. 48. GRE agreed not to include any specific transitional provisions, because the transitional provisions for the 06 series of amendments would also apply to this proposal.

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.

36. The expert from IMMA presented a revised proposal to introduce the possibility of interdependent lamps for dedicated motorcycle lamps into Regulation No. 50 (ECE/TRANS/WP.29/GRE/2014/15, GRE-72-16). GRE adopted the proposal, as amended by Annex XI to this report, and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their March 2015 sessions as draft Supplement 17 to the original version of Regulation No. 50.

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.

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.

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.

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.

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.

43. The expert from France proposed to delete a design restrictive requirement of a minimum luminous flux of 1,000 lm for LED in Regulations Nos. 112 and 123 (ECE/TRANS/WP.29/GRE/2014/35, ECE/TRANS/WP.29/GRE/2014/36, GRE-72-25). The expert from Poland proposed an alternative definition of photometric requirements (GRE-72-24). GRE supported the deletion of the 1,000 lm requirement, but could not agree with the requirement for light distribution of the beam pattern proposed as an alternative. GRE invited the expert from France, in cooperation with the expert from Poland, to prepare a revised proposal for consideration at the next session. All GRE experts were invited to contribute.

67.

The expert from Poland proposed an alternative definition of photometric requirements (GRE-72-24). GRE supported the deletion of the 1,000 lm requirement, but could not agree with the requirement for light distribution of the beam pattern proposed as an alternative. GRE invited the expert from France, in cooperation with the expert from Poland, to prepare a revised proposal for consideration at the next session. All GRE experts were invited to contribute.

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.

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.

36. The expert from IMMA presented a revised proposal to introduce the possibility of interdependent lamps for dedicated motorcycle lamps into Regulation No. 50 (ECE/TRANS/WP.29/GRE/2014/15, GRE-72-16). GRE adopted the proposal, as amended by Annex XI to this report, and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their March 2015 sessions as draft Supplement 17 to the original version of Regulation No. 50.

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.

20. The expert from Germany, referring to ECE/TRANS/WP.29/GRE/2013/18, introduced a revised proposal (ECE/TRANS/WP.29/GRE/2013/62) on avoiding intentional voltage variation of a passing beam using halogen light sources. The expert from the Netherlands proposed clarifications to this proposal (GRE-70-17). The expert from IEC proposed an alternative to this proposal (GRE-70-34). The expert from France requested to simplify this proposal. The expert from Austria expressed reservations about the test procedure proposed in this proposal. The expert from Germany clarified that his proposal addressed and superseded the proposal ECE/TRANS/WP.29/GRE/2013/44 under agenda item 8 below. GRE agreed to revisit this subject at its next session on the basis of a revised document, which the expert from Germany volunteered to prepare, in coordination with the experts from France and IEC.

30. The expert from Germany confirmed that ECE/TRANS/WP.29/GRE/2013/44 was addressed by ECE/TRANS/WP.29/GRE/2013/62 (see agenda item 5(d)) and withdrew this document.

22. The expert from Germany presented a joint proposal by Germany, the Netherlands and IEC, introducing into Regulations Nos. 48 and 112 requirements to avoid intentional non-approved voltage variation of the passing and driving beam for halogen light sources (ECE/TRANS/WP.29/GRE/2014/31, GRE-72-14). The experts from France, Italy, Sweden and UK expressed some concerns and were not in a position to agree to this proposal. GRE decided to revert to this issue at its next session on the basis of a revised proposal to be submitted by the expert from Germany.

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.

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.

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.

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.

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.

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.

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.

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.

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.

8. The expert from Belgium introduced ECE/TRANS/WP.29/GRSG/2013/16 amending the safety prescriptions for trolleybuses to update these according to the respective electrical standard EN 50502. The expert from the Russian Federation introduced GRSG-105-13 listing a number of suggestions to improve the proposed text. GRSG noted some comments supporting the proposals. The Chair invited all experts to send, in due time, their written comments to the expert from Belgium to allow him to prepare a revised proposal. GRSG agreed to resume consideration at its next session on the basis of a revised official document.

44. The expert from Belgium introduced a proposal to amend Regulation No. 10 with prescriptions for electromagnetic compatibility of trolleybuses (ECE/TRANS/WP.29/GRE/2014/41). GRE noted that this amendment had been originally prepared for Regulation No. 107 (General construction of buses and coach), but the Working Party on General Safety Provisions (GRSG) felt that the prescriptions for electromagnetic compatibility of trolleybuses belong to Regulation No. 10 which is under the auspices of GRE. The experts from the Russian Federation and OICA pointed out that the proposed prescriptions for electromagnetic compatibility of trolleybuses do not fit Regulation No. 10, as they are substantially different from the current provisions in this Regulation and would require different testing methods and equipment that are not easily available. GRE agreed to solicit the expert opinions on this issue and to revert to it at its next session. Meanwhile, GRE invited its Chair to bilaterally discuss the issue with the GRSG Chair and, if necessary, to raise it at the November 2014 session of AC.2.

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.

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.

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.

11. The expert from OICA presented a proposal to allow the cornering lamps, used during reversing manoeuvres, to remain ‘ON’ until the vehicle’s forward speed is 10 km/h (ECE/TRANS/WP.29/GRE/2014/40). GRE adopted this proposal and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their March 2015 sessions as a draft Supplements to the 04, 05 and 06 series of amendments to Regulation No. 48.

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.

36. The expert from IMMA presented a revised proposal to introduce the possibility of interdependent lamps for dedicated motorcycle lamps into Regulation No. 50 (ECE/TRANS/WP.29/GRE/2014/15, GRE-72-16). GRE adopted the proposal, as amended by Annex XI to this report, and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their March 2015 sessions as draft Supplement 17 to the original version of Regulation No. 50.

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.

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).

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).

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.

17. The expert from Italy introduced ECE/TRANS/WP.29/GRE/2013/43, on obsolete references in UN Regulations Nos. 53 and 74. GRE agreed to revisit this subject at its next session on the basis of a revised document, which the expert from Italy volunteered to prepare.

23. GRE took note of a revised proposal tabled by the expert from Italy, deleting obsolete references in Regulations Nos. 53 and 74 (ECE/TRANS/WP.29/GRE/2014/38). For Regulation No. 53, the expert from Germany also suggested deleting references to headlamps of Class B of Regulation No. 113 (ECE/TRANS/WP.29/GRE/2014/32), due to their poor performance and related road safety issues. The expert from IMMA pointed out the industry’s need for transitional provisions and presented a first draft of them in GRE-72-19. GRE invited all stakeholders to re-discuss the issues in the above three documents and to transmit a single revised document for consideration at the next 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. The expert from Italy introduced ECE/TRANS/WP.29/GRE/2013/55 as amended by GRE-70-12 on the compliance obligation of lighting components with installation requirements. The proposal received some comments (GRE-70-21). GRE agreed to finalize this subject at its next session on the basis of a revised document, which the expert from Italy volunteered to prepare.

22. The expert from GTB introduced ECE/TRANS/WP.29/GRE/2013/45 as amended by GRE-70-02 clarifying the “type” definition with regard to manufacturer, trade name and marks. GRE adopted this proposal as reproduced in Annex III to the report and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2014 sessions, as part of upcoming amendments to the corresponding UN Regulations, awaiting the adoption of the revised version of ECE/TRANS/WP.29/GRE/2013/55.

73. The representative of EU expressed concerns (WP.29-171-04) about the legal form of amendments relating to the heat test cycle requirement in Regulation No. 113, as contained in ECE/TRANS/WP.29/2017/39 (agenda item 4.9.21). The World Forum decided to refer this document back to GRE for further consideration.

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.

48. The expert from CLEPA presented ECE/TRANS/WP.29/GRE/2013/64 and ECE/TRANS/WP.29/GRE/2013/65, introducing requirements for a new class 5 of devices into Regulation No. 70 and requirements and for a new class F of devices into Regulation No. 104. GRE agreed to revisit this subject at its next session on the basis of revised documents, which the expert from CLEPA volunteered to prepare.

48. The expert from CLEPA presented ECE/TRANS/WP.29/GRE/2013/64 and ECE/TRANS/WP.29/GRE/2013/65, introducing requirements for a new class 5 of devices into Regulation No. 70 and requirements and for a new class F of devices into Regulation No. 104. GRE agreed to revisit this subject at its next session on the basis of revised documents, which the expert from CLEPA volunteered to prepare.

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.

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.

28. The expert from the Netherlands, chairing the informal Group on Agricultural Vehicle Lighting Installation (AVLI), introduced a revised proposal to update Regulation No. 86 (ECE/TRANS/WP.29/GRE/2014/30, GRE-72-02 and GRE-72-12) as well as informed GRE about ongoing activities of AVLI according to Phase II of its mandate. GRE adopted this proposal, as amended by Annex IX to the report, and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their March 2015 sessions as draft Supplement 6 to the original series of amendments to Regulation No. 86.

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).

22. The expert from GTB introduced ECE/TRANS/WP.29/GRE/2013/45 as amended by GRE-70-02 clarifying the “type” definition with regard to manufacturer, trade name and marks. GRE adopted this proposal as reproduced in Annex III to the report and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2014 sessions, as part of upcoming amendments to the corresponding UN Regulations, awaiting the adoption of the revised version of ECE/TRANS/WP.29/GRE/2013/55.

73. The representative of EU expressed concerns (WP.29-171-04) about the legal form of amendments relating to the heat test cycle requirement in Regulation No. 113, as contained in ECE/TRANS/WP.29/2017/39 (agenda item 4.9.21). The World Forum decided to refer this document back to GRE for further consideration.

13. In the view of the ongoing idle period for the existing Regulations (stage 1 of SLR), the expert from Finland sought the consent of GRE to correct a mistake in Supplement 28 to the 01 series of amendments to Regulation No. 6 (GRE-78-06). GRE agreed (see Annex II), and requested the secretariat to submit it, in the proper legal form, to WP.29 and to the Administrative Committee of the 1958 Agreement (AC.1) for consideration and vote at their March 2018 sessions.

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.

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.

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.

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.

36. The expert from IMMA presented a revised proposal to introduce the possibility of interdependent lamps for dedicated motorcycle lamps into Regulation No. 50 (ECE/TRANS/WP.29/GRE/2014/15, GRE-72-16). GRE adopted the proposal, as amended by Annex XI to this report, and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their March 2015 sessions as draft Supplement 17 to the original version of Regulation No. 50.

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.

37. The expert from IMMA introduced a revised proposal allowing for the possibility of installing interdependent lamps for L3 category vehicles in Regulation No. 53 (ECE/TRANS/WP.29/GRE/2014/16). GRE adopted this proposal and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their March 2015 sessions as draft Supplement 15 to the 01 series of amendments to Regulation No. 53.

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.

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.

Proposal unanimously adopted.

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.

12. The expert from Poland presented GRE-70-41, introducing ECE/TRANS/WP.29/GRE/2013/57 and proposing performance based requirements on initial aiming of dipped-beam headlamps as an alternative to the existing requirements. The proposal received some comments (GRE-70-42). The expert from France requested adding proper tolerances from the Conformity of Production provisions. GRE agreed to revisit this subject (on initial aiming and considering the original 50 m visibility distance requirement) at its next session on the basis of a revised document, which the expert from Poland volunteered to prepare.

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.

43. The expert from Japan presented GRE-70-38, supporting GRE-70-30 amending Regulation No. 4 for the purpose of IVWTA. The proposal received some comments. GRE agreed to revisit this item at its next session on the basis of a revised proposal, which the expert from Japan volunteered to prepare.

59. Agenda item 4.6.1, Regulation No. 4, ECE/TRANS/WP.29/2014/54, insert the following amendments, to read:

In the title of the document, replace “Supplement 18” to read “Supplement 17”.

The amendments to Annex 3, correct to read:
“…
Category 1a (340 × 240 mm)
…
Category 1b (520 × 120 mm)
…
Category 1c (255 × 165 mm)
…”

Add the end of the document, correct to read:
“…
q = 145 mm
r = 50 mm

Note: In the case of devices ……"

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.
