1. The Working Party on Lighting and Light-Signalling (GRE) held its seventy-third session from 14 to 17 April 2015 in Geneva, under the chairmanship of Mr. M. Loccufier (Belgium). Experts from the following countries participated in the work according to Rule 1 (a) of the Rules of Procedure of the World Forum for Harmonization of Vehicle Regulations (WP.29) (TRANS/WP.29/690, Amends. 1 and 2): Austria; Belgium; Canada; China; Czech Republic; Finland; France; Germany; Hungary; India; Italy; Japan; Luxemburg; Netherlands; Norway; Poland; Republic of Korea; Russian Federation; Spain; Sweden and the United Kingdom of Great Britain and Northern Ireland (UK). An expert from the European Commission (EC) participated. Experts from the following non‑governmental organizations also took part in the session: European Association of Automotive Suppliers (CLEPA); International Automotive Lighting and Light Signalling Expert Group (GTB); International Electrotechnical Commission (IEC); International Motorcycle Manufacturers Association (IMMA); International Organization of Motor Vehicle Manufacturers (OICA) and Vehicle Lighting Association. Upon invitation of the Chair, the experts from the European Committee of Associations of Manufacturers of Agricultural Machinery (CEMA) participated.

2. GRE considered and adopted the agenda proposed for the seventy-third session (ECE/TRANS/WP.29/GRE/2015/1 and Add.1) as reproduced in GRE-73-01-Rev.1 (including the informal documents distributed during the session). GRE also adopted the running order for the session (GRE-73-07).

5. No proposals were introduced under this agenda item.

6. No new information was reported under this agenda item.

7. GRE took note of the progress of the Informal Working Group on “Simplification of the Lighting and Light-Signalling Regulations” (IWG SLR) and three possible timelines for completing its activities (GRE-73-22). On behalf of IWG SLR, the expert from Germany proposed a concept for simplification based on the introduction of a new part B into Regulation No. 48 and using it as a Horizontal Reference Document (HRD) to which the common provisions of the individual device Regulations would be moved (GRE-73-05-Rev.1). The individual device Regulations would only contain references to part B of Regulation No. 48. A revised Regulation No. 48 and an example of a revised device Regulation were also presented (GRE-73-03 and GRE-73-04). IWG SLR requested GRE to provide guidance on the proposed simplification approach.

8. Various experts reiterated their support to the simplification of the lighting and light-signalling Regulations, but pointed out that, before providing guidance to IWG SLR, they would need more time to study the proposed approach and its consequences. In particular, GRE identified the following issues that would need to be addressed:
a) The impact of amendments (supplements or new series of amendments) to part A and/or part B of Regulation No. 48 on individual device Regulations and vice versa;
b) Some Contracting Parties do not apply Regulation No. 48, but apply specific device Regulations. If the common provisions of these Regulations are included in Regulation No. 48, such Contracting Parties would not be in a position to vote on amendments to these common provisions or object to their adoption;
c) The issues under (a) and (b) above could be solved by moving the common provisions of the device Regulations into a special Resolution similar to R.E.3, rather than to Regulation No. 48. Referencing this Resolution in the device Regulations would make its provisions legally binding;
d) Use of dynamic or static references to HRD in the device Regulations: dynamic references could provide more benefits in terms of simplifying the text, but some Contracting Parties might prefer static references for legal reasons.

9. GRE noted that some of these issues would require guidance from the United Nations Office for Legal Affairs (OLA) and/or WP.29. GRE invited all experts to transmit to the secretariat their comments and questions on the proposed approach before 24 April 2015. The secretariat was requested to seek advice from OLA on legal issues. GRE agreed that the Chair would report to WP.29, at its June 2015 session, on the progress in the simplification of the lighting and light-signalling Regulations and would ask WP.29 to provide guidance on the approach proposed by IWG SLR and, if required, to extend the mandate of the IWG SLR. Meanwhile, IWG SLR was requested to continue its activities to revise device Regulations with a view to preparing a full package for the next session of GRE, bearing in mind that a final decision with regard to HRD (a new part of Regulation No. 48, a new Resolution, etc.) would be taken at a later stage depending on the guidance provided by WP.29 and OLA.

10. On behalf of IWG SLR, the expert from IEC proposed, for the purposes of simplification, to separate data sheets for various light sources from Annex 1 of Regulations Nos. 37, 99 and 128 and to include them in a repository document (resolution) administered by WP.29 (GRE-73-23). GRE noted that this approach had already been endorsed by WP.29 at its November 2014 session and that official documents with amendment proposals would be submitted to the next session of GRE.

GRE-73-23 | Simplification of Light Sources Regulations Nos. 37, 99, 128

11. The expert from GTB proposed to introduce a new category ‘D9S’ of light sources with dual-level operation into Regulation No. 99 (ECE/TRANS/WP.29/GRE/2015/2) as well as to amend the testing and approval provisions in Regulation No. 98 to take into account the multi-level aspects of D9S (ECE/TRANS/WP.29/GRE/2015/15).

12. Several experts pointed out that the lower level of operation of D9S provide for the objective luminous flux of 2000  300 lm, thus avoiding the need for headlamps with such light sources to be equipped with cleaning devices and automatic levelling. GRE recalled that, according to paragraph 6.2.9. of Regulation No. 48, these additional requirements only apply to headlamps with lights sources whose objective luminous flux exceeds 2,000 lm without taking into account the tolerances specified on the relevant data sheet. GRE agreed that, in the future, headlamps with any new light sources could only be exempted from these additional requirements if their objective luminous flux, together with any tolerance, is below 2,000 lm. GTB was requested to prepare a respective proposal for amendments to Regulation No. 48.

13. Upon this understanding, GRE adopted the above proposals and requested the secretariat to submit them to WP.29 and the Administrative Committee of the 1958 Agreement (AC.1) for consideration and vote at their November 2015 sessions as draft Supplement 11 to the original series of Regulation No. 99 and draft Supplement 7 to the 01 series of amendments to Regulation No. 98, respectively.

GRE/2015/15 | Proposal for Supplement 7 to the 01 series of amendments to Regulation No. 98 This is a proposal to introduce a new HID category (D9S) into Regulation No. 99 with dual-level operation, i.e. with two defined wattage values and corresponding luminous flux values. This new category (D9S) is the first light source in R99 that has two defined power levels. When this dual-level light source is used in a headlamp which is being approved according to Regulation No. 98, the testing and approval provisions must be clearly defined in this Regulation to avoid misinterpretation. Therefore, it is proposed to amend the relevant paragraphs of Regulation No. 98 to take into account the multi-level aspects of D9S and possible future multi-level light sources in Regulation No. 99.

GRE/2015/2 | Proposal for Supplement 11 to the original series of Regulation No. 99 Proposal to introduce a new category, 'D9S'.

14. The expert from GTB proposed to clarify the application of paragraph 5.7.1.3. on separating the rear direction indicator lamps and stop lamps (ECE/TRANS/WP.29/GRE/2015/3 and GRE-73-15). The experts of France, Germany, Japan and UK did not support this proposal and pointed out that it was not sufficiently clear and allowed different interpretations. GRE invited GTB to revise the proposal based on the comments received.

GRE-73-15 | Regulation No. 48: Rear direction indicator lamp and stop lamp separation Supplemental presentation in support of document GRE/2015/3: Proposal for Supplement 9 to the 05 series of amendments and Supplement 7 to the 06 series of amendments to Regulation No. 48.

GRE/2015/3 | Proposal for Supplement 9 to the 05 series of amendments and Supplement 7 to the 06 series of amendments to Regulation No. 48 Proposal to improve the applicability of paragraph 5.7.1.3.1. (concerning the separation of grouped direction indicator and stop lamps in order to avoid "signal mix"). To improve the present requirements of paragraph 5.7.1.3.1.on the basis of the colour changes concept, three alternative approaches for a suitable separation of direction indicator lamps and stop lamp are proposed: a) the improved test of the existing paragraph 5.7.1.3.1. clarifies its application to lamps composed of more than one part and deletes the concept of "adjacent" parts of the lamps (that in the past led to different interpretations) in favour of a description of the condition of application of the requirement; b) the unchanged text of the following paragraph 5.7.1.3.2.; c) a new paragraph 5.7.1.3.3. to provide for specific electrical connections of the involved functions, in conjunction with the requirements of paragraph 5.9.2.

15. The expert of GTB presented a proposal to introduce optional variable intensity Daytime Running Lamps (DRL) into Regulations No. 48 (ECE/TRANS/WP.29/GRE/2015/4), together with a proposal to introduce these DRL into Regulation No. 87 (ECE/TRANS/WP.29/GRE/2015/13) (agenda item 7 (g)). Compared to the current DRL with one level of performance between 400 and 1,200 cd for all ambient conditions, the variable intensity DRL were proposed to have several levels of performance between 200 and 2,000 cd, depending on ambient light conditions.

16. The experts from France and Italy were not in a position to accept this proposal. The experts from Germany, Finland, Netherlands, Poland and UK supported the basic concept of variable DRL and suggested some modifications. GRE also recalled that WP.29 urged GRE to find, in close cooperation with all stakeholders, a solution for DRL for the purpose of listing Regulation No. 48 in an annex to UN Regulation No. 0 (IVWTA) (ECE/TRANS/WP.29/1112, para. 43). In this context, the expert from Japan informed GRE that his country was not in a position to support the GTB proposal on road safety concerns for motorcycles, because the figure of 2,000 lm was too high. He also stated that Japan did not want to impede IVWTA and had launched a study on DRL whose outcome would be reported to GRE at the next session. GRE invited GTB to take into account the comments received and to prepare, in cooperation with Japan and other stakeholders, a revised proposal for the next session of GRE.

GRE/2015/13 | Proposal for Supplement 18 to Regulation No. 87 Proposal to introduce provisions for variable intensity daytime running lamps (improving performance under certain outlying ambient light conditions) and to update the heat resistance testing in line with technological progress.

GRE/2015/4 | Proposal for Supplement 9 to the 05 series of amendments and Supplement 7 to the 06 series of amendments to Regulation No. 48 Proposal to introduce variable daytime running lamps into the regulation.

17. The experts from OICA and GTB proposed to introduce new criteria on the automatic levelling of headlamps based on the outcome of the GTB glare and visibility studies (ECE/TRANS/WP.29/GRE/2015/5). The expert from Poland suggested further modifications to this proposal (GRE-73-28). The experts from Germany and Japan proposed to impose automatic levelling in all cases, in order to reduce glare problems for drivers (GRE-73-18). Following an in-depth exchange of views on these three documents, GRE realized that no consensus could be found as long as there was no single proposal.

18. To make progress on this issue and prepare a comprising proposal, GRE decided to establish an Informal Working Group with a draft title “on Visibility, Glare and Levelling” (IWG VGL), for which the experts from Germany and Poland agreed to act as Chair and Secretary, respectively. GRE requested IWG VGL to submit its terms of reference for consideration at the next session of GRE and mandated the Chair to obtain, in June 2015, the consent of WP.29 for the establishment of this IWG.

GRE-73-18 | Comments on the proposal for the 07 series of amendments to Regulation No. 48 Comments on the proposal to introduce new requirements for automatic leveling systems as a means to reduce driver glare (document GRE/2015/5).

GRE-73-28 | Comments on GTB & OICA proposal for the 07 series of amendments to Regulation No. 48

GRE/2015/5 | Proposal for the 07 series of amendments to Regulation No. 48 Proposal to introduce new criteria on the automatic leveling of headlamps based on GTB glare and visibility studies. This proposal is for formal consideration and advice from Contracting Parties, with the expectation that a finalized text will be submitted for adoption at the seventy-fourth session of GRE.

19. The expert from Poland proposed to introduce optional ‘side illuminating lamps’ into Regulations Nos. 48 and 119 (agenda item 7 (l)) (ECE/TRANS/WP.29/GRE/2015/6, ECE/TRANS/WP.29/GRE/2015/19, GRE-73-12, GRE-73-13, GRE-73-27) with the aim to increase the visibility of pedestrians, animals, etc. for glared drivers. The expert from India suggested corrections to this proposal (GRE-73-19). GRE was of the view that this proposal would not bring additional benefits for road safety and was not in a position to support it.

GRE-73-12 | Revised proposal for a Supplement to Regulation No. 48 Proposal to introduce provisions for “side-illuminating lamps” that aim to improve the driver’s visibility over the opposite side of the road (on-coming traffic side) and its buffer zone to mitigate the impact of glare from on-coming vehicles. This submission supersedes the earlier formal document GRE/2015/6.

GRE-73-13 | Revised proposal for Supplement 5 to the 01 series of amendments to Regulation No. 119 Proposal to introduce provisions for “side-illuminating lamps” that aim to improve the driver’s visibility over the opposite side of the road (on-coming traffic side) and its buffer zone to mitigate the impact of glare from on-coming vehicles. This submission supersedes the earlier document GRE/2015/19.

GRE-73-19 | Comments on the proposal to introduce "side-illuminating lamps" into UN Regulation No. 48 Comments on document GRE/2015/6 proposing to introduce provisions for “side-illuminating lamps” that aim to improve the driver’s visibility over the opposite side of the road (on-coming traffic side) and its buffer zone and to mitigate the impact of glare from on-coming vehicles.

GRE/2015/19 | Proposal for Supplement 5 to the 01 series of amendments to Regulation No. 119 Proposal to introduce provisions for “side-illuminating lamps” that aim to improve the driver’s visibility over the opposite side of the road (on-coming traffic side) and its buffer zone to mitigate the impact of glare from on-coming vehicles.

GRE/2015/6 | Proposal for a Supplement to Regulation No. 48 Proposal to introduce provisions for "side-illuminating lamps" that aim to improve the driver's visibility over the opposite side of the road (on-coming traffic side) and its buffer zone to mitigate the impact of glare from on-coming vehicles.

20. The expert from France proposed to delete a design restrictive requirement in Regulation No. 48 for an auto-levelling device for low beam produced by any LED light sources, while for other light sources this requirement exists only if their reference luminous flux exceeds 2,000 Lm (ECE/TRANS/WP.29/GRE/2015/21 and GRE-73-25). According to the expert, should LED be treated in the same way as other lights sources, this would lead to more LED headlamps fitted on new vehicles, thus improving road safety and reducing CO2 emissions. The experts from Belgium, Germany, Japan and UK were of the view that this issue should be first referred to IWG VGL and be considered in one package with other proposals regarding levelling (see paras. 17 and 18 above), upon the understanding that a final solution developed by IWG VGL should be technology neutral. The experts from Italy, Spain, EC, CLEPA and OICA not only supported the French proposal as removing discrimination between various technologies of light sources, but also called for its adoption without delay, irrespective of the IWG activities. GRE agreed that the Chair would submit this issue to the June 2015 session of WP.29 for guidance and to report back to GRE at its next session.

GRE-73-25 | Auto Leveling for LED Headlamps in Regulation No. 48

GRE/2015/21 | Proposal for Supplements to the 04, 05 and 06 series of amendments to Regulations No. 48 Proposal to delete the requirement for automatic leveling devices for all headlamps with light emitting diode (LED) light sources based upon the results of the GTB glare study. The proposal argues that the restriction discriminates against LED light sources based upon an erroneous understanding of light-source relevance to driver glare.

21. GTB proposed to correct an error in Regulation No. 6 (ECE/TRANS/WP.29/GRE/2015/7). GRE approved this proposal, but agreed to postpone to the next session a decision to submit it to WP.29 and AC.1 for consideration and vote, awaiting other possible proposals for amendments to this Regulation in the course of the simplification process.

22. The expert from EC pointed out the administrative burden and legal uncertainty imposed by numerous supplements to lighting and light-signalling Regulations and requested that such amendments be limited to one per year per Regulation. He also expressed concerns about a large number of official documents with amendments proposals submitted by GTB without their prior consideration as informal documents. The expert from GTB stated that his organization would consider how to improve transparency of its work and submissions to GRE. The secretariat clarified that all submissions received earlier than twelve weeks before the session are submitted as official documents for translation, in line with the Rules of Procedure. The expert from UK, chairing the Working Party on Braking and Running Gear (GRRF), informed GRE about the GRRF experiences in dealing with documentation and limiting the number of amendment proposals transmitted to WP.29. Various experts generally supported the idea to collect proposals for amendments to the same Regulation during several sessions of GRE and then to submit them to WP.29 once a year. At the same time, experts called for flexibility and exceptions to this practice, should this be justified by urgent needs of Contracting Parties and/or industry or by emerging new technologies.

23. The Chair drew the following conclusions:
a) Proposals for amendments submitted before the twelve week deadline would continue to be issued as official documents;
b) Official documents submitted to this session of GRE (e.g. ECE/TRANS/WP.29/GRE/2015/7) could be adopted in principle, but put on hold until the next session, pending the outcome of the IWG SLR activities;
c) GRE would collect adopted proposals for amendments to the same Regulation to submit them all together to WP.29 at a certain stage. This general rule should be without prejudice to submitting adopted proposals without delay, based on the grounds of urgency and innovation;
d) The provisional agenda would include a new agenda item for pending amendment proposals.

GRE/2015/7 | Proposal for Supplement 27 to the 01 series of amendments to Regulation No. 6 Proposal to correct an error in Supplement 24 to the 01 series of amendments (document WP.29/2013/14 adopted by the Forum during its March 2013 session). During the compilation of the collective amendment (GRE-68-02-Rev.2), necessary changes to Regulation No. 6 were overlooked. This amendment proposes to align the treatment of categories 1, 1a and 1b with other categories and devices.

24. The expert of GTB introduced ECE/TRANS/WP.29/GRE/2015/8 with a proposal to update the provisions relating to failure of light sources when an operating tell-tale is installed. GRE noted that this document was part of collective amendments to various Regulations (ECE/TRANS/WP.29/GRE/2015/10, ECE/TRANS/WP.29/GRE/2015/11, ECE/TRANS/WP.29/GRE/2015/12, ECE/TRANS/WP.29/GRE/2015/14, ECE/TRANS/ WP.29/GRE/2015/18). Following comments from the experts of Germany and the Netherlands, GRE requested GTB to revise the proposal and submit a new document to the next session.

GRE/2015/10 | Proposal for Supplement 21 to Regulation No. 23 This proposal concerns lamps equipped with several light sources and fitted with an operating tell-tale that indicates the failure of any one of these light sources. The current provisions for the failure of one light source (the “N-1” requirement) are difficult to apply as a complete photometric check for all possible combinations of light source failure is required. The revised text follows the approach of supplement 17 to Regulation No. 87 and removes the requirement to check the complete photometric requirement, in case of failure of any light source, when the lamp is fitted on the vehicle with an operating tell-tale.

GRE/2015/11 | Proposal for Supplement 18 to Regulation No. 38 This proposal concerns lamps equipped with several light sources and fitted with an operating tell-tale that indicates the failure of any one of these light sources. The current provisions for the failure of one light source (the “N-1” requirement) are difficult to apply as a complete photometric check for all possible combinations of light source failure is required. The revised text follows the approach of supplement 17 to Regulation No. 87 and removes the requirement to check the complete photometric requirement, in case of failure of any light source, when the lamp is fitted on the vehicle with an operating tell-tale. In paragraph 9, the opportunity has been taken to correct a reference to paragraph 3. of Annex 4. The reference should be to paragraph 4 of Annex 4.

GRE/2015/12 | Proposal for Supplement 17 to Regulation No. 77 This proposal concerns lamps equipped with several light sources and fitted with an operating tell-tale that indicates the failure of any one of these light sources. The current provisions for the failure of one light source (the “N-1” requirement) are difficult to apply as a complete photometric check for all possible combinations of light source failure is required. The revised text follows the approach of supplement 17 to Regulation No. 87 and removes the requirement to check the complete photometric requirement, in case of failure of any light source, when the lamp is fitted on the vehicle with an operating tell-tale.

GRE/2015/14 | Proposal for Supplement 16 to Regulation No. 91 This proposal concerns lamps equipped with several light sources and fitted with an operating tell-tale that indicates the failure of any one of these light sources. The current provisions for the failure of one light source (the “N-1” requirement) are difficult to apply as a complete photometric check for all possible combinations of light source failure is required. The revised text follows the approach of supplement 17 to Regulation No. 87 and removes the requirement to check the complete photometric requirement, in case of failure of any light source, when the lamp is fitted on the vehicle with an operating tell-tale.

GRE/2015/18 | Proposal for Supplement 5 to the 01 series of amendments to Regulation No. 119 This proposal concerns lamps equipped with several light sources and fitted with an operating tell-tale that indicates the failure of any one of these light sources. The current provisions for the failure of one light source (the “N-1” requirement) are difficult to apply as a complete photometric check for all possible combinations of light source failure is required. The revised text follows the approach of supplement 17 to Regulation No. 87 and removes the requirement to check the complete photometric requirement, in case of failure of any light source, when the lamp is fitted on the vehicle with an operating tell-tale.

GRE/2015/8 | Proposal for Supplement 25 to the 02 series of amendments to Regulation No. 7 This proposal concerns lamps equipped with several light sources and fitted with an operating tell-tale that indicates the failure of any one of these light sources. The current provisions for the failure of one light source (the “N-1” requirement) are difficult to apply as a complete photometric check for all possible combinations of light source failure is required. The revised text follows the approach of supplement 17 to Regulation No. 87 and removes the requirement to check the complete photometric requirement, in case of failure of any light source, when the lamp is fitted on the vehicle with an operating tell-tale.

25. The expert of OICA proposed to allow the designation of manufacturer’s laboratories as approved test laboratories for Regulation No. 10 (ECE/TRANS/WP.29/GRE/2015/9). GRE was not in a position to support this proposal.

GRE/2015/9 | Proposal for Supplement 1 to the 05 series of amendments to Regulation No. 10 Proposal to enable the designation of manufacturer electromagnetic compatibility facilities as approved test laboratories for the purpose of assessing conformity with UN R10.

26. The expert from Belgium referred to their proposal for amendments on the electromagnetic compatibility of trolleybuses (ECE/TRANS/WP.29/GRE/2014/41) and asked GRE to postpone the consideration of this issue to the next session, due to the ongoing consultations with OICA. The expert from the Russian Federation proposed corrections to ECE/TRANS/WP.29/GRE/2014/41 (GRE-73-20). The expert from Canada, who had chaired GRE in 2014, reported on his bilateral consultations with the Chair of the Working Party on General Safety Provisions (GRSG) and their agreement that this issue belongs to the scope of Regulation No. 10 and, thus, should be dealt with by GRE. GRE decided to revert to this matter at the next session and invited the experts from Belgium, the Russian Federation and OICA to submit a joint proposal.

GRE-73-20 | Comments on the proposal to align UN Regulation No. 10 with UN Regulation No. 107 Comments on the proposal to align the requirements of UN Regulation No. 10 with regard to electromagnetic compatibility of trolleybuses with the electrical standards in Annex 12 to UN Regulation No. 107 (document GRE/2014/41).

GRE/2014/41 | Proposal for amendments to Regulation No. 10 Proposal to align the requirements of UN Regulation No. 10 with regard to electromagnetic compatibility of trolleybuses with the electrical standards in Annex 12 to UN Regulation No. 107.

27. GRE noted that this proposal would be considered at the next session in conjunction with a similar proposal for amendments to Regulation No. 7 (see para. 24 of this report).

GRE/2015/10 | Proposal for Supplement 21 to Regulation No. 23 This proposal concerns lamps equipped with several light sources and fitted with an operating tell-tale that indicates the failure of any one of these light sources.

The revised text follows the approach of supplement 17 to Regulation No. 87 and removes the requirement to check the complete photometric requirement, in case of failure of any light source, when the lamp is fitted on the vehicle with an operating tell-tale. In paragraph 9, the opportunity has been taken to correct a reference to paragraph 3. of Annex 4. The reference should be to paragraph 4 of Annex 4.

29. GRE noted that this proposal would be considered at the next session in conjunction with a similar proposal for amendments to Regulation No. 7 (see para. 24 of this report).

GRE/2015/12 | Proposal for Supplement 17 to Regulation No. 77 This proposal concerns lamps equipped with several light sources and fitted with an operating tell-tale that indicates the failure of any one of these light sources.

GRE/2015/15 | Proposal for Supplement 7 to the 01 series of amendments to Regulation No. 98 This is a proposal to introduce a new HID category (D9S) into Regulation No. 99 with dual-level operation, i.e. with two defined wattage values and corresponding luminous flux values. This new category (D9S) is the first light source in R99 that has two defined power levels. When this dual-level light source is used in a headlamp which is being approved according to Regulation No. 98, the testing and approval provisions must be clearly defined in this Regulation to avoid misinterpretation. Therefore, it is proposed to amend the relevant paragraphs of Regulation No. 98 to take into account the multi-level aspects of D9S and possible future multi-level light sources in Regulation No. 99.

33. The expert from GTB proposed to correct editorial errors in the approval markings of Annex 2 (ECE/TRANS/WP.29/GRE/2015/16). GRE approved this proposal, but agreed to postpone to the next session a decision to submit it to WP.29 and AC.1 for consideration and vote, awaiting other possible proposals for amendments to this Regulation in the course of the simplification process.

GRE/2015/16 | Proposal for Supplement 7 to the 01 series of amendments to Regulation No. 112 Correction of errors found in the references to “left-hand traffic” and “right-hand traffic” in the text and associated diagrams of Annex 2 of the regulation.

34. The expert from France proposed to delete a design restrictive requirement (ECE/TRANS/WP.29/GRE/2015/22 and GRE-73-26). This proposal received comments from the experts of Germany and the Netherlands. The expert from Poland suggested a different approach on this issue (GRE-73-21). The Chair invited the experts from France, Germany, Netherlands, Poland, CLEPA and IEC to prepare a revised proposal for the next session.

GRE-73-21 | Proposal for a Supplement to the 01 series of amendments to Regulation No. 112 Proposal to allow LED light source approval based on photometric criteria in place of the current minimum criteria of 1000 lumens.

GRE-73-26 | Conditions on the luminous flux of light sources in Regulations Nos. 112 and 123

GRE/2015/22 | Proposal for a Supplement to the 01 series of amendments to Regulation No. 112 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 because 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.

35. The expert from France proposed to correct an inconsistency in Annex 3 (ECE/TRANS/WP.29/GRE/2015/23). GRE approved this proposal, but agreed to postpone to the next session a decision to submit it to WP.29 and AC.1 for consideration and vote, awaiting other possible proposals for amendments to this Regulation in the course of the simplification process.

GRE/2015/23 | Proposal for a corrigendum to the 01 series of amendments to Regulation No. 112 Proposal to correct an inconsistency between the regulation text and Figure B of Annex 3.

36. At request of the expert from GTB, GRE decided to postpone consideration of this issue to the next session.

GRE/2015/17 | Proposal for Supplement 6 to the 01 series of amendments to Regulation No. 113 Proposal to align the requirements of UN R113 with those adopted in Regulations Nos. 98, 112 and 123 relating to movement of the cut-off line after heat test and to correct an error in the provisions on the use of LED modules.

37. GRE noted that ECE/TRANS/WP.29/GRE/2015/18 would be considered at the next session in conjunction with a similar proposal for amendments to Regulation No. 7 (see para. 24 of this report).

GRE/2015/18 | Proposal for Supplement 5 to the 01 series of amendments to Regulation No. 119 This proposal concerns lamps equipped with several light sources and fitted with an operating tell-tale that indicates the failure of any one of these light sources. The current provisions for the failure of one light source (the “N-1” requirement) are difficult to apply as a complete photometric check for all possible combinations of light source failure is required. The revised text follows the approach of supplement 17 to Regulation No. 87 and removes the requirement to check the complete photometric requirement, in case of failure of any light source, when the lamp is fitted on the vehicle with an operating tell-tale.

38. GRE recalled that a proposal by the expert from Poland to introduce ‘side illuminating lamps’ into Regulation No. 119 (ECE/TRANS/WP.29/GRE/2015/19, GRE-73-13, GRE-73-27) was considered in conjunction with agenda item 6 (b) (see para. 19 above).

GRE-73-13 | Revised proposal for Supplement 5 to the 01 series of amendments to Regulation No. 119 Proposal to introduce provisions for “side-illuminating lamps” that aim to improve the driver’s visibility over the opposite side of the road (on-coming traffic side) and its buffer zone to mitigate the impact of glare from on-coming vehicles. This submission supersedes the earlier document GRE/2015/19.

GRE-73-27 | Side illuminating lamp

GRE/2015/19 | Proposal for Supplement 5 to the 01 series of amendments to Regulation No. 119 Proposal to introduce provisions for “side-illuminating lamps” that aim to improve the driver’s visibility over the opposite side of the road (on-coming traffic side) and its buffer zone to mitigate the impact of glare from on-coming vehicles.

39. The expert from GTB withdrew ECE/TRANS/WP.29/GRE/2015/20.

GRE/2015/20 | Proposal for Supplement 8 to the 01 series of amendments to Regulation No. 123 This proposal corrects a reference and clarifies the text by deleting the words “with each lighting unit” from paragraph 6.3.3.1. This wording is both redundant to Annex 9 and could lead to an incorrect interpretation that each lighting unit shall meet photometric requirement in all cases in conflict with Annex 9.

40. The Secretary to the Working Party on Road Traffic Safety (WP.1) informed GRE that WP.1, at its March 2015 session, had continued considering the amendment proposals on Article 32 and Chapter II of Annex 5 of the Vienna 1968 Convention regarding lighting and light-signalling. The secretariat had been requested to prepare, for the next session, a new revision by incorporating amendment proposals submitted by IMMA. GRE recalled that, once finalized and approved by WP.1, these amendment proposals should be officially forwarded to the UN Secretary-General by one of the Contracting Parties to the 1968 Convention. The WP.1 Secretary reiterated his invitation to GRE experts to discuss this issue at the national level, with a view to finding a volunteer country.

41. No new information was reported under this agenda item.

42. The expert from EC, in his capacity of GRE Ambassador, and the secretariat informed GRE about the progress in preparing Revision 3 of the 1958 Agreement and developing Regulation No. 0 on IWVTA and DETA database. The latest draft of Regulation No. 0 was available in ECE/TRANS/WP.29/2015/68. GRE also noted that IWG IWVTA had proposed to move the installation requirements for DRL from Regulation No. 48 into Regulation No. 87 and that WP.29, at its November 2014 session, urged GRE to find the best solution in close cooperation with the stakeholders. In this respect, GRE discussed whether a new IWG was needed to tackle this issue. Having recalled its earlier considerations (see paras. 15 and 16 above), GRE decided against a new IWG for the time being.

WP.29/2015/68 | Proposal for draft Regulation No. 0 on uniform provisions concerning International Whole Vehicle Type Approval Draft proposal for the regulation to establish an international whole vehicle type approval. This proposal includes tentative text in brackets that is still awaiting final agreement among the Contracting Parties to the 1958 Agreement.

43. No proposals were submitted under this agenda item.

44. The expert from the Netherlands, chairing the informal Group on Agricultural Vehicle Lighting Installation (AVLI), informed GRE about the progress made by AVLI under Phase II of its mandate and introduced a draft proposal for the 01 series of amendments to Regulation No. 86 (GRE-73-02). The experts from Austria, France, Italy and UK commented on this proposal and, in particular, on remaining square brackets in paragraph 6.5.1. and paragraph 3. of Annex 6. GRE invited AVLI to take these comments into account when finalizing the proposal for official submission to the next session of GRE. GRE also noted that Mr. Gerd Kellermann (Germany) would no longer be in a position to co-Chair AVLI and that this position would be taken over by Mr. Timo Kärkkäinen (Finland). GRE thanked that Mr. Kellermann for his contributions and welcomed Mr. Kärkkäinen.

GRE-73-02 | Proposal for draft amendments to Regulation No. 86 Proposal to further update UN R86 which highlights changes being made to Supplement 6 (document WP.29/2015/26 based on GRE/2014/30) adopted during the March 2015 WP.29 session.

45. GRE took note that WP.29, at its March 2015 session, had approved the new definitions of agricultural trailers and towed machinery proposed by GRE for the inclusion into the Consolidated Resolution (R.E.3) (ECE/TRANS/WP.29/1114, para. 67).

46. At the GRSG request, GRE considered proposals for amendments to Regulations Nos. 97 and 116 stipulating that, to provide information on the status of the vehicle alarm system and/or immobilizer, optical displays outside the passenger compartment can be used and that such displays should fulfil the requirements of Regulation No. 48 (ECE/TRANS/WP.29/2015/36, ECE/TRANS/WP.29/2015/37). Some experts expressed concerns that optical displays are not defined in Regulation No. 48. GRE noted that these provisions were intended to prohibit lights that are not in conformity with Regulation No. 48 and did not see the need to intervene with GRSG on this subject.

WP.29/2015/36 | Proposal for Supplement 8 to the 01 series of amendments to Regulation No. 97 Proposal as approved by the GRSG to delete provisions regarding the optical display of the status of the vehicle alarm system outside the passenger compartment in order to avoid driver distraction by and/or confusion of such exterior lighting with primary lighting and signaling equipment required under UN R48.

WP.29/2015/37 | Proposal for Supplement 5 to Regulation No. 116 Proposal as approved by the GRSG to delete provisions regarding the optical display of the status of the vehicle alarm system outside the passenger compartment in order to avoid driver distraction by and/or confusion of such exterior lighting with primary lighting and signaling equipment required under UN R48.

47. At the GRRF request, the secretariat presented the idea of introducing a warning lamp into Regulations Nos. 79 and 13 to light up at any brake application and to indicate the proper functioning of the trailer electrical braking system on some trailers (GRE-73-09). GRE agreed that such lamps do not fall under the scope of Regulation No. 48 and, if required, such an exemption could be introduced explicitly into the definitions of Regulation No. 48.

GRE-73-09 | Trailer-mounted warning lights Discussions have arisen within GRRF concerning failure warnings for trailer direction indicators and brake lights. This paper alerts GRE to the absence of a standardized approach to communicating such lighting failures for trailers which may be a subject for consideration under UN R48.

48. GRE took note of the WP.29 request to complement a list of acronyms/abbreviations (WP.29-165-17) with those used in lighting and light-signalling Regulations. The expert from the Netherlands volunteered to assist the secretariat in this regard. GRE also noted that acronym “REESS” and its definition in Regulation No. 10 might need correction.

WP.29-165-17 | Acronyms/abbreviations in Vehicle Regulations Reference prepared by the WP.29 secretariat

49. The secretariat proposed to correct an error introduced by Supplement 8 to the 01 series of amendments to Regulation No. 74 (GRE-73-10). GRE adopted the proposed correction as contained in Annex II, requested the secretariat to identify its proper legal form (supplement or corrigendum) and submit it to WP.29 and AC.1 for consideration and vote at their June 2015 session.

GRE-73-10 | Proposal for Supplement 9 to the 01 series of amendments to Regulation No. 74 Proposal from the secretariat to correct an error introduced by Supplement 8 to the 01 series of amendments to Regulation No. 74 (WP.29/2014/23).

50. On behalf of the Task Force on Tell-Tales, the expert from the Netherlands proposed amendments to Regulations Nos. 7, 87 and 48 regarding tell-tales indicating a failure (GRE-73-11). To prepare an official document for the next session, he invited GRE experts to send their comments by email.

GRE-73-11 | Proposal to amend the requirements of UN Regulations Nos. 7, 87 and 48 regarding tell-tale indicating a failure Proposals from the GRE Task Force on Tell-tales to clarify the regulations.

51. The expert from IMMA proposed to modify the provisions on the angle of incidence in Annex 5 to Regulation No. 50 (GRE-73-16). GRE noted that this issue should be considered in conjunction with possible changes to Regulation No. 4 and invited CLEPA to look into this issue. IMMA was requested to submit an official document to the next session.

GRE-73-16 | Proposal for a Supplement to Regulation No. 50 Proposal to delete the angle of incidence provision that was developed to ensure that the vehicle registration plate is illuminated. Given current technologies (e.g., LED lamps), the performance requirements of Annex 5 can be met without reference to the angle of incidence.

52. GRE addressed this item in conjunction with agenda item 4 (paras. 7-10 of this report).

53. GRE took note of a status report of the GTB Working Group on Light Sources (GRE-73-24), including the outcome of the GTB LED retrofit feasibility study. Some LED retrofit samples were showcased to demonstrate the equivalence criteria.

GRE-73-24 | Activities of the GTB Working Group on Light Sources Presentation on activities, especially LED retrofit study.

54. GRE decided to keep the same structure of the provisional agenda for the next session, subject to the inclusion of a new item “Pending amendment proposals”. For the 1958 Agreement, the expert from Italy requested a sub-item on Regulation Nos. 53 and 74 be included in the agenda.
