5. No proposals were introduced under this agenda item.

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

7. On behalf of the Informal Working Group “Simplification of the Lighting and Light-Signalling Regulations” (IWG SLR), the expert from IEC introduced a revised proposal for the draft Resolution on the common specification of light source categories (ECE/TRANS/WP.29/GRE/2016/5 and Corr.1, GRE-75-02, GRE-75-03 and GRE-75-04), together with proposals for simplifying Regulations Nos. 37, 99 and 128 by moving light sources data sheets from Annex 1 to these Regulations to the Resolution (ECE/TRANS/WP.29/GRE/2016/2, ECE/TRANS/WP.29/GRE/2016/3 and ECE/TRANS/WP.29/GRE/2016/4). The experts from Germany, France, Italy, UK, CLEPA, GTB and OICA commented on the proposals, in particular on phasing out of light source categories and on the legal form of amendments to Regulations Nos. 37, 99 and 128 (supplements or new series of amendments).

8. GRE adopted the draft Resolution on the common specification of light source categories (ECE/TRANS/WP.29/GRE/2016/5 and Corr.1), as amended by Annex II, and requested the secretariat to submit it to WP.29 for consideration at its November 2016 session. GRE also adopted proposals for amendments to Regulations Nos. 37, 99 and 128 (ECE/TRANS/WP.29/GRE/2016/2, ECE/TRANS/WP.29/GRE/2016/3 and ECE/TRANS/WP.29/GRE/2016/4) not amended 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 2016 sessions as, respectively, draft Supplement 45 to the 03 series of amendments to Regulation No. 37, draft Supplement 12 to the original version of Regulation No. 99 and draft Supplement 6 to the original version of Regulation No. 128. The expert of Germany reserved his position on the adopted proposals.

GRE-75-02 | Modifications to the draft Resolution on the common specification of light source categories (ECE/TRANS/WP.29/GRE/2015/28) Proposal from the Informal Working for a new Resolution on light sources to simplify the content and amendment process for the light-source regulations UN R37, 99 and 128. The data sheets for light sources are moved from Annexes 1 of these Regulations to the draft Resolution. In addition, the draft phases out some filament light source categories (per the earlier document GRE/2015/29), add new LED categories LW3, LY3, LR5, LW5, and LY5 (per document GRE/2015/30), and aligns drawings of category LR4 with drawings of these new categories. These latter items were all approved during the 74th GRE session.

GRE-75-03 | Modifications to Annex 1 to the draft Resolution on the common specification of light source categories (ECE/TRANS/WP.29/GRE/2015/28)

GRE-75-04 | Modifications to Annex 3 to the draft Resolution on the common specification of light source categories (ECE/TRANS/WP.29/GRE/2015/28) Amendments to the proposal by the Informal Working Group “Simplification of the Lighting and Light-Signalling Regulations” (SLR) to simplify the content and amendment process of the light source Regulations Nos. 37, 99 and 128.

GRE/2016/2 | Proposal for Supplement 45 to the 03 series of amendments to Regulation No. 37 Proposal from the Informal Working Group “Simplification of the Lighting and Light-Signalling Regulations” (SLR) to simplify the content and amendment process of the light source Regulations.

GRE/2016/3 | Proposal for Supplement 12 to the original version of Regulation No. 99 Proposal from the Informal Working Group “Simplification of the Lighting and Light-Signalling Regulations” (SLR) to simplify the content and amendment process of the light source Regulations.

GRE/2016/4 | Proposal for Supplement 6 to the original version of Regulation No. 128 Proposal from the Informal Working Group “Simplification of the Lighting and Light-Signalling Regulations” (SLR) to simplify the content and amendment process of the light source Regulations.

GRE/2016/5 | Proposal for a draft Resolution on the common specification of light source categories Proposal from the informal working group on the Simplification of Lighting Regulations to consolidate data sheets for light-source categories (UN R37 on filament lamps, UN R99 on gas-discharge light sources, and UN R128 on LED light sources). The data sheets for light sources are moved from Annexes 1 of these Regulations to the proposed Resolution. Moreover, the proposals to phase out some filament light source categories (ECE/TRANS/WP.29/GRE/2015/29), to introduce new LED light source categories LW3, LY3, LR5, LW5 and LY5 and to align some drawings of category LR4 (ECE/TRANS/WP.29/GRE/2015/30), all adopted by the Working Party on Lighting and Light-Signalling at its seventy-fourth session, were merged with this proposal.

GRE/2016/5/Corr.1 | Corrigendum to Proposal for a draft Resolution on the common specification of light source categories

9. The expert from GTB, in his capacity of Secretary of IWG SLR, reported on the progress of IWG SLR and a new phased approach to simplification of the lighting and light-signalling Regulations developed by IWG SLR (GRE-75-05). The proposed approach would include the following major steps:

a) Review and adoption of pending amendment proposals to consolidate the existing Regulations;
b) Freeze of the existing Regulations which would be superseded by three new Regulations (see point c) below);
c) Establishment of three new Regulations on road illumination devices, light-signalling devices and retro-reflective devices based on the text of existing Regulations;
d) Further amendment of the new Regulations and Regulation No. 48 to introduce technologically neutral and performance-based requirements.

10. According to IWG SLR, the proposed approach would not only simplify the Regulations and provide legal certainty, but would also remove unnecessary barriers to innovations and promote worldwide application of lighting and light-signalling Regulations, for example, through the development of GTRs in this area and/or more countries joining the 1958 Agreement.

11. A vast majority of GRE experts expressed their support to the proposed approach and activities of IWG SLR. The expert from Germany reserved his position. The experts of Japan and OICA stressed the need to find a way to introduce new technologies, should they emerge during a transition period between the freeze of the current Regulations and the entry into force of the three new ones. The experts from Belgium and UK were of the view that the United Nations Office for Legal Affairs (OLA) should be requested to provide guidance on the approach. The Chair invited experts to submit further comments, if any, before 29 July 2016.

12. To seek the consent of WP.29 on the proposed concept, GRE requested the Chair to present it at the June 2016 meeting of the World Forum as well as to ask WP.29 to extend the mandate of IWG SLR. GRE also took note of a list of pending proposals, which had been referred to IWG SLR in 2014-2015 (GRE-75-06), and decided to consider them at the next session under agenda item “Pending proposals”.

13. The expert from GTB informed GRE about activities of the GTB Working Group Light Sources and its plans to extend Regulation No. 128 to light sources for forward lighting applications covered by Regulations Nos. 19, 98, 112, 113 and 123 (GRE-75-14). Proposals for amendments to Regulation No. 128 would include performance-based requirements for visibility and glare as well as introduce thermal grades for light emitting diodes (LED) light sources which could be subject to heat from a combustion engine. Forward lighting Regulations Nos. 19, 98, 112, 113 and 123 would need to be amended to accept LEDs of Regulation No. 128 and their thermal grades. GRE took note that amendment proposals would be submitted to the next session. A number of experts posed questions on the thermal grade concept proposed by GTB and were of the view that a detailed clarification should be included in the justification part of future documents.

14. The expert from GTB briefed GRE on activities of the GTB Task Force Conformity of Production (GRE-75-15) and its intention to submit a formal document to the next session of GRE with a view to harmonizing the conformity of production provisions of Regulation No. 123 with those of other headlamp Regulations (e.g. No. 112), for the sake of simplification. The experts from France and UK requested GTB to include a solid justification in their future submission.

15. The expert from GTB proposed to clarify the interpretation of the specifications of filament lamp category H19 in Regulation No. 37 (ECE/TRANS/WP.29/GRE/2016/6). GRE adopted this proposal and agreed that it should be incorporated into the draft Resolution on the common specification of light source categories (see para. 8 above) and submitted to WP.29 for consideration at its November 2016 session.

16. The expert from the Netherlands, in his capacity of Chair of the Task Force on Tell-Tales (TF TT), introduced revised proposals for amendments to Regulations Nos. 48, 7 and 87 on tell-tales which indicate a failure (ECE/TRANS/WP.29/GRE/2016/7, ECE/TRANS/WP.29/GRE/2016/12 and ECE/TRANS/WP.29/GRE/2016/17). GRE adopted the proposals and decided to submit them to WP.29 and AC.1 for consideration and vote at their November 2016 sessions as draft Supplement 17 to the 04 series of amendments, draft Supplement 10 to the 05 series of amendments and draft Supplement 8 to the 06 series of amendments to Regulation No. 48, draft Supplement 25 to the 02 series of amendments to Regulation No. 7 and draft Supplement 18 to Regulation No. 87.

17. Several experts pointed out that the adopted amendments might also require an amendment to paragraph 5.4. of Regulation No. 121 (Identification of controls, tell-tales and indicators), but no consensus was reached on this issue. GRE invited the Working Party on General Safety Provisions (GRSG), which deals with Regulation No. 121, to address this matter.

GRE/2016/12 | Proposal for Supplement 25 to the 02 series of amendments to Regulation No. 7 Proposal from the Task Force on Tell-Tales to clarify the requirement for failure indicators.

GRE/2016/17 | Proposal for Supplement 18 to Regulation No. 87 Proposal from the Task Force on Tell-Tales to clarify the requirements for failure indication.

GRE/2016/7 | Proposal for supplements to the 04, 05, and 06 series of amendments to UN Regulation No. 48 Proposal from the Task Force on Tell-Tales for Supplement 17 to the 04 series of amendments, for Supplement 10 to the 05 series of amendments and Supplement 8 to the 06 series of amendments to Regulation No. 48.

18. To improve road safety, the expert from Germany proposed to reduce the intensity of a daytime running lamp (DRL) in situations where a direction indicator is activated during the functioning of DRL (ECE/TRANS/WP.29/GRE/2016/8). The document also proposed amendments to Regulation No. 87. The expert from OICA suggested an alternative wording (GRE-75-11, GRE-75-11-Rev.1). The experts from France, the Netherlands and UK supported the proposal of Germany. The expert from Italy was of the view that the proposal should be accompanied with transitional provisions. GRE decided to continue its deliberations at the next session based on a revised document to be submitted by the expert from Germany.

GRE-75-11 | Proposal for amendments to ECE/TRANS/WP.29/GRE/2016/8 OICA proposal to amend the German proposal to clarify the requirements with regard to daytime running lamps and direction indicators in order to prevent DRL from masking or otherwise interfering with the visibility of the direction indicator lamps.

GRE-75-11/Rev.1 | Revised proposal for amendments to ECE/TRANS/WP.29/GRE/2016/8 Revised proposal to clarify the requirements with regard to daytime running lamps and direction indicators in order to prevent DRL from masking or otherwise interfering with the visibility of the direction indicator lamps.

GRE/2016/8 | Proposal for collective amendments to Regulation No. 48 (Installation of lighting and light-signalling devices) and Regulation No. 87 Proposal to clarify the requirements with regard to daytime running lamps and direction indicators in order to prevent DRL from masking or otherwise interfering with the visibility of the direction indicator lamps. Germany believes that the current text produces different interpretations with different results that risk degrading vehicle safety.

19. The expert from GTB proposed to clarify the text of paragraph 6.21.1.2.4. of Regulation No. 48 (ECE/TRANS/WP.29/GRE/2016/9). GRE adopted the proposal and decided to submit it to WP.29 and AC.1 for consideration and vote at their November 2016 sessions as draft Supplement 17 to the 04 series of amendments, draft Supplement 10 to the 05 series of amendments and draft Supplement 8 to the 06 series of amendments to Regulation No. 48

GRE/2016/9 | Proposal of supplements to the 04, 05, and 06 series of amendments to UN Regulation No. 48 Proposal for Supplement 17 to the 04 series of amendments, Supplement 10 to the 05 series of amendments and Supplement 8 to the 06 series of amendments to Regulation No. 48. The proposal seeks to clarify paragraph 6.21.1.2.4. with regard to the application of conspicuity markings on bodywork made of flexible material.

20. The expert from GTB proposed modifications to the transitional provisions of various series of amendments to allow for optional installation of new equipment on a vehicle, which had already been approved to an earlier series of amendments, by extending the existing approval, rather than requesting a new approval based on the latest series of amendments (ECE/TRANS/WP.29/GRE/2016/10). The expert from OICA advocated the proposal and pointed out that it would contribute to increasing traffic safety (GRE-75-12). The experts from Finland, Italy and Netherlands also supported the proposal. The experts from Austria, France and UK expressed concerns about too many series of amendments to Regulation No. 48 in force and were not convinced that the earlier series should be amended. GRE decided to continue this discussion at the next session.

GRE-75-12 | OICA comments on document GRE/2016/10 Document GRE/2016/10 proposed to refine the transitional provisions of UN R48 pursuant to possibilities for the application of the regulation within the International Whole Vehicle Type Approval system. Since IWVTA allows for approvals to earlier versions of current regulations, the possibility exists where optional installation of advanced equipment could entail mandatory compliance with the latest version of UN R48. However, UN R48 imposes broad requirements such that efforts to add certain safety equipment are hindered by concerns over compliance with a broad range of requirements under the latest version of UN R48 that raises the consumer price to prohibitive levels. Therefore, OICA supports the solution proposed by GTB (document GRE/2016/10).

GRE/2016/10 | Proposal for amendments to the 03, 04, 05 and 06 series of amendments to Regulation No. 48. Proposal to further refine the transitional provisions of UN R48. In 2014, the transitional provisions of UN R48 were changed in order to avoid having more than one series of amendments in force at the same time (via Supplement 3 to the 06 series of amendments). This change allows earlier series of amendments to be "frozen" and used under the International Whole Vehicle Type Approval system (IWVTA) as "versions" of UN R48. However, the possibility for the partial application of a series of amendments resulting from the installation of new equipment on a vehicle approved to an earlier series has been raised within the IWVTA. This proposal refines the transitional provisions in order to enable partial application of a series through an extension of the existing approval rather by requiring a new approval. At the same time, the proposal aims to ensure that the safety objectives of UN R48 are met.

21. The expert from Poland, in his capacity of Co-Chair of the Informal Working Group on Visibility, Glare and Levelling (IWG VGL), reported on the IWG activities and requested GRE to provide guidance on a number of issues, including but not limited to:

a) Which factors with potential impact on visibility and glare should be addressed by IWG;
b) Whether the work should focus only on Regulation No. 48 (i.e., M and N categories of vehicles) or other categories (L and T) should be considered as well;
c) Whether the requirement for periodic technical inspections (PTI) should be included in the scope;
d) To which extent the available studies and previous GRE documents should be taken into account;
e) Whether IWG or GRE should vote on issues for which no consensus had been found.

22. Various experts stressed the complexity of these issues and called for a pragmatic approach that would rely on the available studies and proposals. The experts from Germany and Japan were of the view that automatic levelling should be taken out of the scope of IWG VGL and addressed by GRE directly. The experts from France and Italy felt that both manual and automatic levelling should be considered by IWG VGL.

23. Based on the above discussion, GRE requested IWG VGL to review its Terms of Reference and prepare modifications for adoption by GRE, as may be necessary. GRE also agreed that, for the time being, IWG VGL should focus on Regulation No. 48 and vehicle categories M and N only, leaving aside the PTI requirements. Finally, GRE stressed the need to follow a consensus approach rather than to vote on controversial points. GRE noted that the expert from Germany would no longer be in a position to co-Chair IWG VGL and encouraged other experts to volunteer for this post.

GRE-75-17 | Outcome of the 2nd VGL informal group session

24. The expert from GTB proposed to align the requirements of paragraph 6.1. with the definition of “single lamp”. A similar proposal was prepared for Regulation No. 7. (ECE/TRANS/WP.29/GRE/2016/11). 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, in order to collect other proposals for amendments into a single package.

GRE/2016/11 | Proposal for Supplement 26 to the 01 series of amendments to Regulation No. 6 and Supplement 24 to the 02 series of amendments to Regulation No. 7 Proposal to align the text in the header row of the table in paragraph 6.1 (light emitted by the lamps) with the definitions used in Regulation No. 48 for the installation of "single lamps", "lamps marked D" and "interdependent lamps".

25. The expert from Germany invited GRE to consider interpretation of the “One Continuous Line” requirement in paragraph 5.6. c) of Regulation No. 6 (GRE-75-10). To this end, he proposed to establish a Task Force. Following support of the experts from France, Italy, Netherlands, Spain and UK, GRE agreed to establish a Task Force. The experts from Finland and GTB volunteered to act as Chair and Secretary of the Task Force, respectively.

GRE-75-10 | Interpretation of the "One Continuous Line" requirement Request for interpretation on approvals of LED direction indicators integrated with daytime running lamps and using sequential activation of horizontal bars. Germany proposes a task for on sequential activation of direction indicators to develop clear provisions within the regulation, especially with regard to paragraph 5.6 <notextile>(c)</notextile>: sequential activation ... shall be one continuous line with no repeating alternation in the vertical direction.

26. GRE recalled that ECE/TRANS/WP.29/GRE/2016/12 had been discussed and adopted together with ECE/TRANS/WP.29/GRE/2016/7 (see para. 16 above).

GRE/2016/12 | Proposal for Supplement 25 to the 02 series of amendments to Regulation No. 7 Proposal from the Task Force on Tell-Tales to clarify the requirement for failure indicators.

27. GRE noted that ECE/TRANS/WP.29/GRE/2016/11 had been adopted under agenda item 7 (a) (see para. 24 above).

GRE/2016/11 | Proposal for Supplement 26 to the 01 series of amendments to Regulation No. 6 and Supplement 24 to the 02 series of amendments to Regulation No. 7 Proposal to align the text in the header row of the table in paragraph 6.1 (light emitted by the lamps) with the definitions used in Regulation No. 48 for the installation of "single lamps", "lamps marked D" and "interdependent lamps".

28. The expert from GTB withdrew ECE/TRANS/WP.29/GRE/2016/13 with proposals for amendments to Regulations Nos. 6, 23, 38, 77, 91 and 119. GRE noted that this document also contained an additional proposal of the secretariat to correct a mistake that had been introduced by Supplement 22 to the 02 series of amendments to Regulation No. 7. GRE adopted a correction, as laid down in Annex III of the GRE-75 session report, and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their November 2016 sessions.

GRE/2016/13 | Proposal for collective amendments to Regulations No. 7, 23, 38, 77, 91, and 119 Proposal to refine the requirements for lamps equipped with several light sources, including in systems fitted with an operating tell-tale that indicates the failure of any one of these light sources. In the case of failure of any one light source in a single lamp containing more than one light source, either the light intensity must comply with the minimum intensity required in the table of standard light distribution in space or, for lamps used in systems where a tell-tale indicates the failure of any one of the light sources, the light intensity in the axis of reference must be at least 50 per cent of the minimum intensity required.

29. On behalf of the Task Force on Electromagnetic Compatibility (TF EMC), the expert from OICA reported on the activities of TF EMC (GRE-75-13, GRE-75-18). As a first step, TF EMC clarified the operating modes of trolleybuses and the applicable EMC Regulations or standards. According to Regulation No. 107, trolleybuses are dual-mode vehicles operating either: (a) in the trolley mode, when connected to the overhead contact line (OCL), or (b) in the bus mode when not connected to OCL. When not connected to OCL, they can also be (c) in the charging mode. The expert from OICA pointed out that for mode (a) the railway EMC standard IEC 62236-3-1 was applicable, while for modes (b) and (c) Regulation No. 10 should apply. TF EMC had also identified that, in the bus mode with a diesel engine, other Regulations (e.g. Nos. 13, 49, 51, 89 and 100) could be affected. TF EMC recommended seeking guidance from WP.29 on how to proceed with the treatment of trolleybuses in the framework of various Regulations and WP.29 Working Parties. To this end, the expert from OICA offered to produce an informal document for the June 2016 session of WP.29. He also stated that OICA would submit an informal document on this issue to GRSG and possibly to other WP.29 Working Parties.

30. The experts from France and the Russian Federation were of the view that Regulation No. 10 would be the best place to include the EMC provisions for trolleybuses. The expert from Germany felt that Regulation No. 10 could not be amended to incorporate the railway EMC standards for the trolley mode. The expert from the Russian Federation informed GRE about recent testing of the disturbances caused by trolleybuses and requested exclusion of the low-frequency range from 9 to 150 kHz from consideration, due to the very low level of detected disturbances and expensive measurement equipment required for this range.

31. GRE noted that the Chair would consider asking guidance of WP.29 and/or AC.2 at their June 2016 sessions and decided to continue the discussion at its next session.

32. The expert from GTB proposed to correct the specifications of the mixture for the dirt test. Similar proposals were also prepared for Regulations Nos. 45, 98, 112, 113 and 123 (ECE/TRANS/WP.29/GRE/2016/14). GRE adopted these proposals, as contained in Annex IV of the GRE-75 session report, but agreed that only the amendment to Regulation No. 45 should be submitted to WP.29 and AC.1 for consideration and vote at their November 2016 sessions as draft Supplement 10 to the 01 series of amendments to Regulation No. 45. For the amendment proposals to Regulations Nos. 19, 98, 112, 113 and 123, GRE postponed to the next session a decision to submit them to WP.29 and AC.1 for consideration, in order to collect other proposals for amendments into a single package.

GRE/2016/14 | Proposal for a collective amendment to Regulations Nos. 19, 45, 98, 112, 113 and 123 Proposal to amend the formula for the dirt mixture used in testing to address an error introduced by Supplement 9 to the 01 series of amendments to UN R45 where the specified quantity of "2 &plusmn; 1 parts by weight" of surfactant results in invalid testing. The correct specification should be "2 &plusmn; 1 drops" of surfactant. While GTB notes that the specification should eventually be incorporated differently under the pending simplification of lighting regulations, the organization strongly urges amending UN R45 as quickly as possible.

33. The expert from GTB withdrew their proposal to update the provisions on failure of light sources when a tell-tale indicating failure is installed (ECE/TRANS/WP.29/GRE/2016/13).

GRE/2016/13 | Proposal for collective amendments to Regulations No. 7, 23, 38, 77, 91, and 119 Proposal to refine the requirements for lamps equipped with several light sources, including in systems fitted with an operating tell-tale that indicates the failure of any one of these light sources. In the case of failure of any one light source in a single lamp containing more than one light source, either the light intensity must comply with the minimum intensity required in the table of standard light distribution in space or, for lamps used in systems where a tell-tale indicates the failure of any one of the light sources, the light intensity in the axis of reference must be at least 50 per cent of the minimum intensity required.

34. See para. 33 under agenda item 7.(e) Regulation No. 23 (Reversing lamps) above.

35. The expert from GTB proposed to correct the specifications of the mixture for the dirt test. Similar proposals were also prepared for Regulations Nos. 45, 98, 112, 113 and 123 (ECE/TRANS/WP.29/GRE/2016/14). GRE adopted these proposals, as contained in Annex IV of the GRE-75 session report, but agreed that only the amendment to Regulation No. 45 should be submitted to WP.29 and AC.1 for consideration and vote at their November 2016 sessions as draft Supplement 10 to the 01 series of amendments to Regulation No. 45. For the amendment proposals to Regulations Nos. 19, 98, 112, 113 and 123, GRE postponed to the next session a decision to submit them to WP.29 and AC.1 for consideration, in order to collect other proposals for amendments into a single package.

GRE/2016/14 | Proposal for a collective amendment to Regulations Nos. 19, 45, 98, 112, 113 and 123 Proposal to amend the formula for the dirt mixture used in testing to address an error introduced by Supplement 9 to the 01 series of amendments to UN R45 where the specified quantity of "2 &plusmn; 1 parts by weight" of surfactant results in invalid testing.

While GTB notes that the specification should eventually be incorporated differently under the pending simplification of lighting regulations, the organization strongly urges amending UN R45 as quickly as possible.

36. The expert from IMMA recalled their earlier proposal to amend the angle of incidence for the rear registration plate illuminating device (ECE/TRANS/WP.29/GRE/2015/38) and requested GRE to postpone consideration of this issue to the next session.

GRE/2015/38 | Proposal for Supplement 18 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.

37. The expert from GTB proposed to allow the activation of additional lighting units, in conjunction with the driving beam, to improve illumination when the motorcycle is banking (ECE/TRANS/WP.29/GRE/2016/15). GRE adopted the proposal and decided to submit it to WP.29 and AC.1 for consideration and vote at their November 2016 sessions as draft Supplement 19 to the 01 series of amendments and draft Supplement 1 to the 02 series of amendments to Regulation No. 53.

GRE/2016/15 | Proposal for Supplement 19 to the 01 series of Regulation No. 53 Proposal to remove restrictions that impede the use of bend lighting on motorcycles. UN R53 currently prohibits the use of additional lighting units when the driving beam is in use. This requirement unnecessarily restricts the use of ALU to improve road illumination at night when the motorcycle is banking through a turn.

38. The expert from IMMA recalled their earlier proposal to allow for the use of different brake lamp activation methods and to align the brake lamp provisions with those applicable for four-wheelers (ECE/TRANS/WP.29/GRE/2015/42) and requested GRE to postpone consideration of this issue to the next session.

GRE/2015/42 | Proposal for Supplement 18 to the 01 series of amendments to Regulation No. 53 Proposal to allow the use of different brake lamp activation methods and to align the brake lamp provision with those applicable for four-wheelers.

39. The expert from Japan proposed to automatically switch from the daytime running lamp (DRL) to the headlamp at night. The experts from Austria, France, Germany, India, Netherlands, UK and IMMA commented on the proposal. GRE encouraged all experts to study the proposal and to provide their comments, if any, by the end of June 2016. GRE also invited the expert from Japan to take these comments into consideration and to submit an official document to the next session.

GRE-75-08 | Proposal for the 03 series of amendments to Regulation No. 53 Proposal to require automatic switching of motorcycle daytime running lamps to headlamp illumination at night. The concern is that DRL are left on, causing glare. This proposal aligns with the provisions of UN R48.

GRE-75-09 | Research on Daytime Running Lamps of Motorcycles Presentation in support of Japan's proposal to require automatic switching between daytime running lamps and headlamps as a measure to prevent safety risks from DRL glare during night driving.

40. The expert from GTB withdrew their proposal to update the provisions on failure of light sources when a tell-tale indicating failure is installed (ECE/TRANS/WP.29/GRE/2016/13).

GRE/2016/13 | Proposal for collective amendments to Regulations No. 7, 23, 38, 77, 91, and 119 Proposal to refine the requirements for lamps equipped with several light sources, including in systems fitted with an operating tell-tale that indicates the failure of any one of these light sources. In the case of failure of any one light source in a single lamp containing more than one light source, either the light intensity must comply with the minimum intensity required in the table of standard light distribution in space or, for lamps used in systems where a tell-tale indicates the failure of any one of the light sources, the light intensity in the axis of reference must be at least 50 per cent of the minimum intensity required.

41. The expert from the Netherlands, on behalf of the Informal Working Group on Agricultural Vehicle Lighting Installation (AVLI), recalled considerations at the previous session of GRE (ECE/TRANS/WP.29/GRE/74, paras. 31 and 32) and introduced a revised proposal for the 01 series of amendments to Regulation No. 86 (ECE/TRANS/WP.29/GRE/2016/16). GRE adopted the proposal and decided to submit it to WP.29 and AC.1 for consideration and vote at their November 2016 sessions. GRE also noted that the EU member States would check the consistency between the EU legislation and the proposed 01 series of amendments to Regulation No. 86.

GRE/2016/16 | Revised proposal for the 01 series of amendments to Regulation No. 86 Proposal by the GRE Informal Group “Agricultural Vehicles Lighting Installation” (AVLI) to update and revise Regulation No. 86, superseding document GRE/2015/43.

42. GRE recalled that a proposal by the expert from Germany to improve road safety in situations where a direction indicator is activated during the functioning of a DRL (ECE/TRANS/WP.29/GRE/2016/8) was addressed under agenda item 6 (a) (see para. 18 above).

GRE/2016/8 | Proposal for collective amendments to Regulation No. 48 (Installation of lighting and light-signalling devices) and Regulation No. 87 Proposal to clarify the requirements with regard to daytime running lamps and direction indicators in order to prevent DRL from masking or otherwise interfering with the visibility of the direction indicator lamps. Germany believes that the current text produces different interpretations with different results that risk degrading vehicle safety.

43. GRE noted that ECE/TRANS/WP.29/GRE/2016/17 was discussed and adopted together with ECE/TRANS/WP.29/GRE/2016/7 (see para. 16 above).

GRE/2016/17 | Proposal for Supplement 18 to Regulation No. 87 Proposal from the Task Force on Tell-Tales to clarify the requirements for failure indication.

44. The expert from GTB withdrew their proposal to update the provisions on failure of light sources when a tell-tale indicating failure is installed (ECE/TRANS/WP.29/GRE/2016/13).

GRE/2016/13 | Proposal for collective amendments to Regulations No. 7, 23, 38, 77, 91, and 119 Proposal to refine the requirements for lamps equipped with several light sources, including in systems fitted with an operating tell-tale that indicates the failure of any one of these light sources. In the case of failure of any one light source in a single lamp containing more than one light source, either the light intensity must comply with the minimum intensity required in the table of standard light distribution in space or, for lamps used in systems where a tell-tale indicates the failure of any one of the light sources, the light intensity in the axis of reference must be at least 50 per cent of the minimum intensity required.

45. The expert from GTB proposed to correct the specifications of the mixture for the dirt test. Similar proposals were also prepared for Regulations Nos. 45, 98, 112, 113 and 123 (ECE/TRANS/WP.29/GRE/2016/14). GRE adopted these proposals, as contained in Annex IV of the GRE-75 session report, but agreed that only the amendment to Regulation No. 45 should be submitted to WP.29 and AC.1 for consideration and vote at their November 2016 sessions as draft Supplement 10 to the 01 series of amendments to Regulation No. 45. For the amendment proposals to Regulations Nos. 19, 98, 112, 113 and 123, GRE postponed to the next session a decision to submit them to WP.29 and AC.1 for consideration, in order to collect other proposals for amendments into a single package.

GRE/2016/14 | Proposal for a collective amendment to Regulations Nos. 19, 45, 98, 112, 113 and 123 Proposal to amend the formula for the dirt mixture used in testing to address an error introduced by Supplement 9 to the 01 series of amendments to UN R45 where the specified quantity of "2 &plusmn; 1 parts by weight" of surfactant results in invalid testing. The correct specification should be "2 &plusmn; 1 drops" of surfactant. While GTB notes that the specification should eventually be incorporated differently under the pending simplification of lighting regulations, the organization strongly urges amending UN R45 as quickly as possible.

46. The expert from Poland proposed to introduce a new optional “Class B1” headlamp (ECE/TRANS/WP.29/GRE/2016/18). The proposal received remarks from the experts of Germany, Netherlands, UK, CLEPA, GTB and OICA. Some experts pointed out that they would need more time to study the proposal and that it could be considered by IWG SLR when developing performance-based requirements in the future (para. 9 (d) above). GRE invited all experts to send their comments to the expert from Poland and decided to keep this issue on the agenda of the next session.

GRE/2016/18 | Proposal for Supplement 7 to the 01 series of amendments to Regulation No. 112 Proposal to introduce a new optional “Class B1” headlamp. The proposal would establish photometric requirements for Class B1 based on average real performance of present Class B (halogen/LED) but would not include additional design restrictions such as the luminous flux of light source.

47. GRE recalled that ECE/TRANS/WP.29/GRE/2016/14 with the proposal of GTB to correct the specifications of the mixture for the dirt test was considered under agenda item 7 (d) (see para. 32 above).

GRE/2016/14 | Proposal for a collective amendment to Regulations Nos. 19, 45, 98, 112, 113 and 123 Proposal to amend the formula for the dirt mixture used in testing to address an error introduced by Supplement 9 to the 01 series of amendments to UN R45 where the specified quantity of "2 &plusmn; 1 parts by weight" of surfactant results in invalid testing.

51. GRE recalled a number of pending amendment proposals to various Regulations adopted at this (ECE/TRANS/WP.29/GRE/2016/11, ECE/TRANS/WP.29/GRE/2016/14 and Annex IV) and previous sessions (ECE/TRANS/WP.29/GRE/2015/7, ECE/TRANS/WP.29/GRE/2015/16, ECE/TRANS/WP.29/GRE/2015/23), as well as the proposals which had been referred to IWG SLR in 2014-2015 (GRE-75-06, see para. 12 above). GRE decided to review all these proposals at the next session in order to submit a comprehensive package to WP.29 for consideration at its March 2017 session. Following that, the Regulations concerned would be frozen until the finalization of the simplification process (see para. 9 above).

52. The secretariat informed GRE that the Working Party on Road Traffic Safety (WP.1), at its March 2016 session, had continued considering amendment proposals on Article 32 and Chapter II of Annex 5 of the Vienna 1968 Convention regarding lighting and light-signalling. In particular, WP.1 started discussing a proposal by Italy, France and Laser Europe to rearrange the text of the Convention, including Chapter II of Annex 5 (ECE/TRANS/WP.1/2015/2/Rev.2). The discussion would continue at the next session of WP.1.

WP.1/2015/2/Rev.2 | Amendments to the Convention on Road Traffic (1968) Proposal by Italy, France and Laser Europe to rearrange the text of the Convention, including Chapter II of Annex 5.

53. The secretariat informed GRE about a statement of Mr. Jean Todt, United Nations Special Envoy for Road Safety, at the March 2016 session of WP.29 in which he had encouraged vehicle manufacturers to commit to better safety standards for developing and least developed countries. GRE also noted that the United Nations General Assembly was expected to adopt in April 2016 a new resolution on road safety.

54. The secretariat briefed GRE on the progress in preparing Revision 3 of the 1958 Agreement, Regulation No. 0 on IWVTA and an electronic database for the exchange of type approval documentation (DETA). The expert from Japan pointed out that his Government had decided to accept DRLs and was preparing for their introduction, thus paving the way for including Regulation No. 48 in an Annex to UN Regulation No. 0. The expert from EC informed GRE about internal consultations with the aim to decide whether or not he could continue to act as GRE ambassador to IWVTA.

55. The expert from Germany informed GRE about the progress on the test method for the sun load impact on stop lamps and direction indicators (so-called “phantom effect”) (GRE-75-16).

GRE-75-16 | Status report on investigating the test method for the sun load impact Presentation on the "phantom effect" of sunlight reflection on vehicle taillights, its role as a causation factor in road accidents, and research on a possible test method to evaluate light-signaling performance towards avoiding light washout under certain ambient conditions.

56. GRE took note that WP.29, at its March 2016 session, had referred ECE/TRANS/WP.29/2016/24 on Regulation No. 113 back to GRE. The expert from GTB clarified that this was due to unclear provisions for the cut-off line in Annexes 4 and 5. He further pointed out that similar provisions had already been introduced in Regulations Nos. 98, 112 and 123, and that GTB would prepare collective amendments to all these Regulations for consideration at the next session of GRE. At the same time, GRE noted that the remaining provisions of ECE/TRANS/WP.29/2016/24 did not seem to create any problem and requested the secretariat to issue them as a separate document and to submit it to WP.29 and AC.1 for consideration and vote, possibly already at their June 2016 sessions. [Note: The remaining provisions were reintroduced in document WP.29/2016/74 for the June 2016 WP.29 session.]

WP.29/2016/24 | 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.

WP.29/2016/74 | 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.

57. Mr. Walter Nissler, Chief, Vehicle Regulations and Transport Innovations Section (VRTIS), informed GRE about the abolishment of several General Service (G) posts within the United Nations Economic Commission for Europe (UNECE) as decided by the United Nations General Assembly in December 2015. He further explained that one of these G posts had been cut in VRTIS as of 1 January 2016, due to the imminent retirement of the current incumbent. He pointed out that UNECE was reallocating staff resources to accommodate this cut and that, during this period, a lower level of services provided by the Section might be expected. He also informed GRE about the new UNECE publications on child restraint systems and motorcycle helmets. Finally, Mr. Nissler reported on the efforts of UNECE to include the costs of hosting the DETA database in the UNECE regular budget, following a decision of the Inland Transport Committee at its February 2016 session.

58. GRE addressed this item in the framework of simplification of lighting and light-signalling Regulations (paras. 7-14 above) and decided not to include it in the agenda of the next session.

59. GRE noted that the status reports of the GTB Working Groups were presented under agenda item 4 (paras. 13 and 14 above).

GRE-75-14 | Extension of Regulation 128 towards Light Sources for Forward Lighting Applications

GRE-75-15 | Report of the GTB Task Force on Conformity of Production

60. GRE decided to keep the same structure of the provisional agenda for the next session, except for the deletion of item 11 (a) (para. 58 above).
