29. GRE was briefed on the progress of the task force on the signalling requirements for automated/autonomous vehicles (TF AVSR) (GRE-81-08-Rev.1 and GRE-81-12-Rev.1). GRE noted that TF had not been able to reply to the main question on whether or not there should be a safety requirement for automated/autonomous vehicles to provide specific signals. GRE was not in a position to reach a consensus on this question either. While some experts felt that such signals were necessary for safety reasons, some others held a different view. The expert of SAE pointed out that his organization was developing lamps for automated/autonomous vehicles. GRE decided to request WP.29 for guidance on this matter. The Chair invited GRE experts to provide him with arguments for the request to WP.29 at its session in June 2019.

18. The expert from the GRE special interest group introduced a consolidated proposal for a new 07 series of amendments (ECE/TRANS/WP.29/GRE/2019/11, GRE-81-09 and GRE-81-10). The expert from France proposed an additional modification (ECE/TRANS/WP.29/GRE/2019/4). Following in-depth discussion, GRE agreed that, given the complexity of the proposal, further work should be pursued by means of a task force. The experts from the Netherlands and Finland volunteered to act as Chair and Co-Chair, respectively, while the expert from OICA agreed to become secretary. GRE noted that the next session of the special interest group/task force would be convened on 16 and 17 May 2019 at the OICA office in Paris (GRE-81-24).

12. The expert from Germany presented a draft Supplement to the UN LSD Regulation which introduced requirements for testing the sun load impact (ECE/TRANS/WP.29/GRE/2019/7). The proposal received comments from the experts of France, Japan (GRE-81-17), Netherlands, United Kingdom of Great Britain and Northern Ireland, CLEPA, OICA and SAE. The expert from IMMA made a study reservation. The Chair invited the expert from Germany to update the proposal, based on the comments received, for consideration at the next session.

18. The expert from Germany presented an updated proposal which introduces requirements for testing the sun load impact into UN Regulation No. [148] (ECE/TRANS/WP.29/GRE/2019/22). He further indicated that these amendments should be introduced by a new 01 series of amendments to UN Regulation No. [148], together with transitional provisions. The proposal received comments from Japan (GRE-82-38). The experts from the United Kingdom, CLEPA and OICA requested justification for additional testing in ECE/TRANS/WP.29/GRE/2019/22. Finally, GRE invited the expert from Germany, in cooperation with Japan, CLEPA and OICA, to complement the document with transitional provisions and research justification.

20. The expert from India requested a postponement of consideration of his proposal to make the fitment of front position lamps optional, due to the introduction of automatic headlamp switching and DRL provisions (GRE-81-18).

29. The expert from India proposed making optional the fitment of front position lamps, due to the introduction of auto headlamp switching, and alternatively DRL provisions in UN Regulation No. 53 (ECE/TRANS/WP.29/GRE/2018/47 and GRE-80-26). The experts of Finland, Germany and UK expressed doubts. The Chair concluded that there was not enough support for the proposal and proposed to revert to this issue at the next session. He also invited the expert from India to try to convince the experts in doubt before the next session.

8. The expert from the Informal Working Group “Simplification of the Lighting and Light-Signalling Regulations” (IWG SLR) reported on their progress and requested guidance from GRE (GRE-81-19). The expert from Poland commented on the IWG SLR request (GRE-81-22). GRE agreed that:

• The headlamp provisions should continue to be expressed in terms of the luminous intensities equivalent to the illuminance measured on a screen at a distance of 25 m.
• All technologies should be allowed for all SLR functions. Requirements should be common for all technologies; test requirements could be technology-specific.
• Combination of different light source technologies should be possible for all SLR functions.

9. The expert from IWG SLR requested advice on various options of how to use the Unique Identifier (UI) for the new simplified UN Regulations (GRE-81-20). GRE mandated the secretariat to send GRE-81-20 to IWG on Database for the Exchange of Type Approval documentation (DETA) for comments, and requested IWG SLR to consider delegating one of its experts to participate in IWG DETA sessions. Finally, GRE decided to revert to this issue at the next session.

30. The expert from GTB presented their activity report and mentioned several ongoing studies which were scheduled to be completed by July 2019 (GRE-81-23). GRE looked forward to receiving the results of the studies.

18. The expert from the GRE special interest group introduced a consolidated proposal for a new 07 series of amendments (ECE/TRANS/WP.29/GRE/2019/11, GRE-81-09 and GRE-81-10). The expert from France proposed an additional modification (ECE/TRANS/WP.29/GRE/2019/4). Following in-depth discussion, GRE agreed that, given the complexity of the proposal, further work should be pursued by means of a task force. The experts from the Netherlands and Finland volunteered to act as Chair and Co-Chair, respectively, while the expert from OICA agreed to become secretary. GRE noted that the next session of the special interest group/task force would be convened on 16 and 17 May 2019 at the OICA office in Paris (GRE-81-24). The expert from SAE invited the task force to also address the earlier proposal of SAE on side retro-reflectors (GRE-80-17). Finally, GRE agreed to continue consideration of proposals for a new 07 series of amendments at the next session.

2. GRE considered and adopted the agenda (ECE/TRANS/WP.29/GRE/2019/1), as reproduced in GRE-81-01 together with the informal documents distributed during the session and subject to the addition of a new agenda item 8 (d) “Other business: International events in automotive lighting”. GRE also noted the running order proposed by the Chair (GRE-81-11).

22. The expert from the Netherlands tabled a revised proposal that requires mandatory installation of direction indicators on mopeds (ECE/TRANS/WP.29/GRE/2019/2 and GRE-81-02-Rev.1). GRE adopted the proposal, as laid down in Annex IV, and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2019 sessions as draft 02 series of amendments to UN Regulation No. 74.

32. The expert from the Netherlands presented an updated proposal that required the mandatory installation of direction indicators on mopeds. (ECE/TRANS/WP.29/GRE/2018/52). Following a brief discussion, GRE invited the proponent to redraft the transitional provisions and to submit a revised document for consideration to the next session.

10. The expert from IWG SLR presented a proposal for a new 07 series of amendments to UN Regulation No. 48 (ECE/TRANS/WP.29/GRE/2019/3). The expert from Poland commented on the proposal (GRE-81-13 and GRE-81-16). GRE focused its discussion on the aiming diagram in paragraph 6.2.6.1.2. Following an in-depth consideration, GRE agreed on a modified diagram (GRE-81-21 and Annex II) and requested IWG SLR to prepare, on the basis of the new diagram, a revised proposal for consideration at the next session. The experts from Germany and Poland made study reservations. The expert from Germany also pointed out that, at the next session, he would present the outcome of a research project on the issue.

25. The expert from Poland, in his capacity of Chair of the Informal Working Group on Visibility, Glare and Levelling (IWG VGL), briefed GRE on the IWG activities (GRE-78-36). He introduced a proposal and justification for a new diagram that defines the limits of a new aiming range for the dipped-beam headlamp (GRE-78-23-Rev.1) by lines. He also proposed to delete the 2,000 lm criterion (GRE-78-32).

26. For line 1, GRE generally agreed to a move to the right to the 0.2 per cent mark. Several experts also agreed that this shift should correspond with a shift of line 4 to retain the 1.6 per cent tolerance. The experts from Poland and UK pointed out the need for additional justification of tolerances for moving line 4, and invited OICA to provide the necessary details. Based on the GRE considerations, the experts from Italy, Netherlands, UK and OICA offered to prepare an amendment proposal for consideration at the next session.

29. The expert from Poland provided a summary of initial aiming and levelling tolerance issue (GRE-79-23, GRE-79-24). The experts from Italy and the Netherlands briefly introduced GRE-79-29 as a discussion paper for the possible introduction of new requirements for headlamp levelling, in particular on the vertical inclination in relation to the dipped-beam headlamp mounting height. GRE agreed to keep GRE-79-29 as a reference document for the next session.

31. The expert from IWG SLR recalled the previous discussions on the aiming diagram in paragraph 6.2.6.1.2. (ECE/TRANS/WP.29/GRE/81, para. 10 and Annex II) and presented GRE-82-25, which had been prepared in line with the GRE request. The expert from Poland proposed a revised diagram (GRE-82-43). For the diagram in GRE-82-25, the experts from Japan, Poland and the United Kingdom expressed their preference to maintain the 2000 lm criteria for automatic levelling and headlamp cleaning. The experts from Germany and the United Kingdom pointed out the need to consider the aiming tolerance for the purposes of, respectively, Periodic Technical Inspections (PTI) and Conformity of Production (CoP). GRE requested IWG SLR to consider the above elements and to prepare a revised document for the next session of GRE.

18. The expert from the GRE special interest group introduced a consolidated proposal for a new 07 series of amendments (ECE/TRANS/WP.29/GRE/2019/11, GRE-81-09 and GRE-81-10). The expert from France proposed an additional modification (ECE/TRANS/WP.29/GRE/2019/4). Following in-depth discussion, GRE agreed that, given the complexity of the proposal, further work should be pursued by means of a task force. The experts from the Netherlands and Finland volunteered to act as Chair and Co-Chair, respectively, while the expert from OICA agreed to become secretary. GRE noted that the next session of the special interest group/task force would be convened on 16 and 17 May 2019 at the OICA office in Paris (GRE-81-24). The expert from SAE invited the task force to also address the earlier proposal of SAE on side retro-reflectors (GRE-80-17). Finally, GRE agreed to continue consideration of proposals for a new 07 series of amendments at the next session.

16. The expert from Czechia proposed to clarify the requirements for headlamps and DRL (ECE/TRANS/WP.29/GRE/2019/5). GRE adopted the proposals and requested the secretariat to submit them to WP.29 and AC.1 for consideration at their November 2019 sessions as draft Supplement 13 to the 06 series of amendments to UN Regulation No. 48.

19. The experts from the Czech Republic, Italy and Japan proposed amendments to the provisions on automatic switching between daytime running lamps (DRL) and headlamps in the 06 series of amendments to Regulation No. 48 (GRE-77-06-Rev.1 and GRE-77-10-Rev.1). The proposals received comments from the expert of the Russian Federation (GRE-77-23 and GRE-77-24). GRE realized that the proposed amendments addressed two different issues: (i) deletion of several subparagraphs that were transitional provisions only for the 05 series of amendments, but were kept by mistake in the 06 series of amendments as well, and (ii) clarification of the requirements for automatic switching from DRL to headlamps. With regard to (i), GRE adopted the proposals for amendments, as contained in Annex II, and requested the secretariat to submit them to WP.29 and AC.1 for consideration and vote at their November 2017 sessions. Concerning (ii), GRE agreed to establish a task force to consider this issue in detail. The experts from the Netherlands and OICA volunteered to act as, respectively, Chair and Secretary of the task force.

11. The experts from France and Germany proposed introducing conditions for the use of logos inside the illuminating surface of a signalling lamp in the UN LSD Regulation and UN Regulation No. 48 (ECE/TRANS/WP.29/GRE/2019/6). Various experts commented and posed questions on the proposal. GRE noted that a clear definition of “logo” would be needed and that technological neutrality should be ensured. The expert from EC was of the view that the underlying issue did not have bearing on road safety and, thus, should not be discussed by GRE. The proponents agreed to revise the proposal in accordance with the comments received. The expert of OICA offered its assistance.

39. Due to a lack of time, GRE was not in a position to consider GRE-78-03.

37. The experts of France and Germany presented the preliminary results of their questionnaire on national treatment of evocative, suggestive or figurative apparent surfaces (GRE-80-28). GRE noted that the reported results seemed to indicate the need to harmonize national regulations on the issue. GRE decided to continue this discussion at the next session, based on a more detailed document to be prepared by the experts from France and Germany.

16. The experts from France and Germany presented an updated proposal for amendments to UN Regulations Nos. 48 and 148, which introduce conditions for the use of logos of the vehicle or body manufacturer inside the illuminating surface of a signalling lamp (ECE/TRANS/WP.29/GRE/2019/28 and GRE-82-32). The expert from CLEPA proposed adding the logo of the lamp manufacturer (GRE-82-20). The expert from OICA suggested a modified definition of “manufacturer logo” (GRE-82-36).

17. Several experts expressed their preference to completely prohibit the use of logos inside the lamps on safety concerns, while some others pointed out that road safety would not be compromised, as the lamps should meet all requirements in the respective UN Regulations. Some experts wondered whether the use of letters inside the logos was allowed. Following an in-depth discussion, GRE agreed that the “manufacturer logo” definition would need further clarification and invited the experts from France and Germany to submit a revised proposal for consideration at the next session. Pending the outcome of this discussion, GRE invited type approval authorities to refrain from granting type approvals to signalling lamps with logos inside the illuminating surface.

24. The experts from France and Germany introduced a revised proposal for amendments to UN Regulations Nos. 48 and 148 that regulates the use of manufacturer logos inside the illuminant surface of a lamp (ECE/TRANS/WP.29/GRE/2020/5 and GRE-83-50). The experts from the Russian Federation and OICA commented on the proposal (GRE-83-36 and GRE-83-46). Taking into account concerns expressed by the experts from EC and the Russian Federation, GRE invited the authors to liaise with those experts and to prepare an updated text for the next session. In the interim, GRE reiterated its request to type approval authorities to refrain from granting type approvals to lamps with such logos.

12. The expert from Germany presented a draft Supplement to the UN LSD Regulation which introduced requirements for testing the sun load impact (ECE/TRANS/WP.29/GRE/2019/7). The proposal received comments from the experts of France, Japan (GRE-81-17), Netherlands, United Kingdom of Great Britain and Northern Ireland, CLEPA, OICA and SAE. The expert from IMMA made a study reservation. The Chair invited the expert from Germany to update the proposal, based on the comments received, for consideration at the next session.

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).

17. The expert from Germany proposed to allow (a) the manual switch-off of all lighting devices in vehicles used by special forces and (b) the activation of hazard warning lights when opening a door in vehicles not equipped with a door assistance and warning system (ECE/TRANS/WP.29/GRE/2019/8). The experts from France, Japan and United Kingdom of Great Britain and Northern Ireland were not in a position to support the derogation (a) and indicated that such exceptions should be done in the national or regional legislation, rather than in a UN Regulation. For proposal (b), the expert from EC pointed out that it constitutes a new requirement and, thus, should be introduced by a new series of amendments. The experts from Czechia, Netherlands, United Kingdom of Great Britain and Northern Ireland and OICA were of the view that proposal (b) goes beyond the scope of GRE and should be addressed by the Working Party on General Safety Provisions (GRSG). The Chair requested the secretariat to bring the issue to the attention of GRSG.

26. The expert from Germany tabled a proposal that allows the manual switch-off of all lighting devices in vehicles used by authorities responsible for maintaining public order (ECE/TRANS/WP.29/GRE/2019/14 and GRE-82-41-Rev.1). Some experts were of the view that such a derogation should be addressed in the framework of national or regional rather than international law. Several experts indicated practical difficulties in identifying those vehicles when at the stage of type approval and manufacturing. GRE agreed to revert to the issue at the next session.

13. The expert of GTB presented an amendment proposal to the Consolidated Resolution on the common specification of light source categories (R.E.5) that introduced new light emitting diode (LED) substitute light source categories C5W/LEDK and R5W/LED (ECE/TRANS/WP.29/GRE/2019/9 and GRE-81-03). The expert of GTB also tabled another proposal that introduced new LED substitute light source categories W5W/LEDK and WY5W/LED (ECE/TRANS/WP.29/GRE/2019/10 and GRE-81-04). The expert from IEC highlighted the interlock solutions for the new categories (GRE-81-07). GRE adopted both proposals and requested the secretariat to submit them to WP.29 and the Administrative Committee (AC.1) for consideration at their November 2019 sessions as draft amendment 4 to R.E.5.

79. The World Forum approved the amendments to the Consolidated Resolution on the common specification of light source categories (R.E.5).

79. The World Forum approved the amendments to the Consolidated Resolution on the common specification of light source categories (R.E.5).

18. The expert from the GRE special interest group introduced a consolidated proposal for a new 07 series of amendments (ECE/TRANS/WP.29/GRE/2019/11, GRE-81-09 and GRE-81-10). The expert from France proposed an additional modification (ECE/TRANS/WP.29/GRE/2019/4). Following in-depth discussion, GRE agreed that, given the complexity of the proposal, further work should be pursued by means of a task force. The experts from the Netherlands and Finland volunteered to act as Chair and Co-Chair, respectively, while the expert from OICA agreed to become secretary. GRE noted that the next session of the special interest group/task force would be convened on 16 and 17 May 2019 at the OICA office in Paris (GRE-81-24). The expert from SAE invited the task force to also address the earlier proposal of SAE on side retro-reflectors (GRE-80-17). Finally, GRE agreed to continue consideration of proposals for a new 07 series of amendments at the next session.

24. Due to lack of time, GRE could not consider ECE/TRANS/WP.29/GRE/2017/23, ECE/TRANS/WP.29/GRE/2017/24, GRE-77-25 and GRE-78-05.

23. The expert from GTB introduced amendment proposals with the aim to reduce discomfort glare from rear signalling lamps when viewed at close proximity in slow moving traffic (ECE/TRANS/WP.29/GRE/2018/51). The expert from OICA suggested further improvements (GRE-80-20). Following an exchange of comments, GRE invited GTB, OICA and other interested parties to produce a revised document for consideration at the next session.

24. GRE considered a proposal for a new 07 series of amendments prepared by the former Co-Chairs of the Task Force on Headlamp Switching (TF HS), which updated the requirements for headlamps and daytime running lamps (DRL) (ECE/TRANS/WP.29/GRE/2018/44, GRE-80-09 and GRE-80-10). The experts from EC and Japan, Russian Federation, OICA and SAE commented on the proposal (respectively, GRE-80-22, GRE-80-29, GRE-80-18 and GRE-80-07). Separately, the expert from EC proposed a new requirement of mandatory presence of emergency stop signal (ESS) on all categories of motor vehicles and trailers (GRE-80-08) and the expert from SAE submitted an amendment proposal on side retro-reflectors (GRE-80-17).

25. Following a brief exchange of views on the above proposals, GRE noted that each of them would require a new series of amendments to UN Regulation No. 48 with its own transitional provisions. To avoid amending this UN Regulation too many times and practical complications, GRE was of the view that all proposals should be consolidated into a single new 07 series of amendments. The expert from OICA offered to host in December 2018, at their premises in Paris, a special meeting of interested parties with a view to drafting a consolidated proposal for the next session of GRE.

30. On behalf of SIG, the expert from OICA introduced a proposal for a new series of amendments which clarifies the definitions of “switching” and “activation” and introduces the mandatory use of Emergency Stop Signal (ESS) (ECE/TRANS/WP.29/GRE/2019/29, GRE-82-06 and GRE-82-11). The experts from EC and OICA suggested modified transitional provisions (GRE-82-23, GRE-82-34 and GRE-82-44-Rev.1). Finally, GRE adopted the proposal, as amended by Annex IV, and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their March 2020 sessions as draft 07 series of amendments to UN Regulation No. 48.

19. The expert from IMMA recalled the draft 03 series of amendments to UN Regulation No. 53 adopted at the previous session of GRE (ECE/TRANS/WP.29/GRE/2018/50 and ECE/TRANS/WP.29/GRE/80, para. 28) and proposed to restore the original automatic headlamp requirement for vehicles not equipped with daytime running lamps (DRL) (ECE/TRANS/WP.29/GRE/2019/12). GRE adopted the proposal and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2019 sessions as part of the draft 03 series of amendments to UN Regulation No. 53. The expert from EC was not in a position to support the proposal.

28. On behalf of the Special Interest Group for DRL of L-category vehicles, the expert from Japan presented a revised proposal that introduced a new requirement for automatic switching from DRL to the headlamp for L3 category in UN Regulation No. 53 as well as a corresponding amendment to the new LSD UN Regulation (ECE/TRANS/WP.29/GRE/2018/50). The expert from India proposed to delete references to “passing beam” (GRE-80-25). The experts of Germany, Netherlands, UK and EC were not in favour of deleting “passing beam” and supported the original proposal. GRE adopted the proposal and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their June 2019 sessions as draft 03 series of amendments to UN Regulation No. 53 and draft Supplement 1 to the original LSD UN Regulation, subject to the following amendments:

Paragraphs 5.11.1.1., 5.11.1.2. and Annex 7 (twice), replace “headlamp [(passing beam)]” with “passing beam”.

Paragraphs 11.8. and 11.10., remove square brackets around 2023.

35. The expert from IMMA presented a consolidated text of the draft 03 series of amendments to UN Regulation No. 53 which had incorporated the latest modifications to the 01 and 02 series (ECE/TRANS/WP.29/GRE/2019/23 and GRE-82-16). GRE noted that these modifications had been also included in the draft 03 series of amendments to UN Regulation No. 53 submitted for consideration of WP.29 and AC.1 in November 2019 (ECE/TRANS/WP.29/2019/80).

37. The expert from EC recalled the draft 03 series of amendments to UN Regulation No. 53, which were submitted for consideration of WP.29 and AC.1 in November 2019 (ECE/TRANS/WP.29/2019/80) and proposed to shorten its transitional period from 1 September 2023 to 1 September 2021 (GRE-82-22). The expert from IMMA pointed out the technical challenges of implementing the 03 series of amendments and suggested that the original transitional provisions should be maintained (GRE-82-37). Following an in-depth discussion, GRE decided to keep the transitional period unchanged. At the same time, GRE agreed to scrutinize all future requests for long transitional provisions by the industry.
