1. The Working Party on Lighting and Light-Signalling (GRE) held its eightieth session from 23 to 26 October 2018 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, ECE/TRANS/WP.29/690/Amends. 1 and 2): Belgium, China, Czechia, Finland, France, Germany, Hungary, India, Italy, Japan, Latvia, Luxembourg, Netherlands, Norway, Poland, Republic of Korea, Serbia, Spain, Switzerland, 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 Automobile Federation (FIA), 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), Society of Automotive Engineers (SAE).

2. GRE considered and adopted the agenda (ECE/TRANS/WP.29/GRE/2018/31), as reproduced in GRE-80-01 together with the informal documents distributed during the session. GRE also noted the running order proposed by the Chair (GRE-80-11).

3. The list of informal documents is contained in Annex I to the report. The list of GRE informal groups is reproduced in Annex V to the session report.

4. GRE took note of the highlights of the June 2018 session of WP.29 and the official document submission deadline of 18 January 2019 for the April 2019 session of GRE (GRE-80-15).

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.

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.

30. The expert from IMMA proposed to clarify the use of direction indicators to show the status of the device for protection of a vehicle against unauthorised use (ECE/TRANS/WP.29/GRE/2018/45). GRE adopted the proposal and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their March 2019 sessions as draft Supplement 3 to the 02 series and draft Supplement 21 to the 01 series of amendments to UN Regulation No. 53.

31. The expert from IMMA presented a revised proposal on exterior courtesy lamps (ECE/TRANS/WP.29/GRE/2018/46). GRE adopted the proposal and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their March 2019 sessions as draft Supplement 3 to the 02 series and draft Supplement 21 to the 01 series of amendments to UN Regulation No. 53, subject to the following modification:

New paragraph 6.15.19.3., second indent, delete “…one or more of…”.

27. The expert from OICA, on behalf of the Task Force on Electromagnetic Compatibility (TF EMC), presented their progress report (GRE-80-12-Rev.1) and revised proposals for the 06 series of amendments to UN Regulation No. 10 (ECE/TRANS/WP.29/GRE/2018/43 and GRE-80-13). For L-category vehicles, the expert of IMMA proposed to limit the scope of this UN Regulation to categories L6 and L7 only (GRE-80-31). GRE supported the IMMA proposal. The expert of Japan proposed to exclude agricultural vehicles (categories T, R and S) from the scope (GRE-80-24). Following a discussion, the expert from Japan was in a position to accept categories T, R and S in the scope. Finally, GRE adopted the amendment proposals, as amended by Annex IV, and requested the secretariat to submit them to WP.29 and AC.1 for consideration at their March 2019 sessions as a new 06 series of amendments to UN Regulation No. 10.

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.

5. GRE noted that, in the future, a new UN Global Technical Regulation (UN GTR) could be developed under stage 2 of the simplification of the lighting and light-signalling UN Regulations (SLR) (see para. 7 below) or as a result of consideration of light-signalling functions of automated/autonomous vehicles (see para. 40 below).

6. No information was reported under this agenda item.

7. The Secretary of the Informal Working Group “Simplification of the Lighting and Light-Signalling UN Regulations” (IWG SLR) presented their progress report (GRE-80-30) and proposed revising its Terms of Reference (GRE-80-14). Following an in-depth discussion, GRE agreed that stage 2 of IWG SLR should take over the outcome of the Informal Working Group on Visibility, Glare and Levelling (IWG VGL), and so, adopted the revised Terms of Reference and Rules of Procedure of IWG SLR, as laid down in Annex II. GRE mandated its Chair to seek the consent of WP.29, at its November 2018 session, to extend the mandate of IWG SLR until the end of 2022. At the same time, GRE agreed not to extend the mandate of IWG VGL beyond 2018.

8. GRE was informed that the full package of amendment proposals drafted by IWG SLR under stage 1 of SLR, including the three new simplified UN Regulations on Light-Signalling Devices (LSD), Road Illumination Devices (RID) and Retro-Reflective Devices (RRD), in August 2018 had been submitted to WP.29 and to the Administrative Committee of the 1958 Agreement (AC.1) for consideration at their November 2018 sessions. GRE noted that the SLR package, if adopted, would be scheduled to enter into force at the end of May – beginning of June 2019. Therefore, under the above assumption, the June 2019 sessions of WP.29 and AC.1 would provide for the very first opportunity to introduce amendments to the new LSD, RID and RRD UN Regulations.

9. GRE recalled that, at its previous session, it had provisionally adopted transitional provisions to “freeze” UN Regulations Nos. 3, 4, 6, 7, 19, 23, 27, 38, 50, 69, 70, 77, 87, 91, 98, 104, 112, 113, 119 and 123 (ECE/TRANS/WP.29/GRE/2018/11), with square brackets around the third transitional provision on the validity of existing type approvals, and had agreed to take a final decision at this session (ECE/TRANS/WP.29/GRE/79, paras. 11 and 17). The Secretary of IWG SLR presented the revised transitional provisions (ECE/TRANS/WP.29/GRE/2018/34) which propose the deletion of the third transitional provision for all concerned UN Regulations. The expert from OICA expressed concerns that this deletion might lead to different interpretation among type approval authorities and that some of them might question the validity of existing type approvals (GRE-80-21). GRE confirmed that the revised transitional provisions, as proposed in ECE/TRANS/WP.29/GRE/2018/34, do not affect the validity of type approvals already granted pursuant to the UN Regulations concerned.

10. Upon this understanding, GRE adopted ECE/TRANS/WP.29/GRE/2018/34 and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2018 sessions as corrigenda to the original SLR package. GRE also expressed a hope that, in spite of the late submission of these modifications, contracting parties would be in a position to take them into consideration and to vote for the complete updated SLR package in November 2018.

11. The Secretary of IWG SLR introduced the first proposals for amendments to the original versions of the LSD, RID and RRD UN Regulations (ECE/TRANS/WP.29/GRE/2018/36, ECE/TRANS/WP.29/GRE/2018/37 and ECE/TRANS/WP.29/GRE/2018/38). GRE adopted these proposals and noted that some of these amendments were essentially corrections of errors in the original SLR package while others were improvements. GRE stressed the need to rectify the discovered errors, such as the correction of Table 9 in the RID UN Regulation (as proposed in ECE/TRANS/WP.29/GRE/2018/37) and the correction of Annex 7 of the RRD UN Regulation (as proposed in ECE/TRANS/WP.29/GRE/2018/38) and requested the secretariat to submit these corrections to WP.29 and AC.1 for consideration at their November 2018 sessions as corrigenda to the original SLR package. The “improvement” amendments would be submitted to WP.29 and AC.1 for consideration at their June 2019 sessions, as explained in para. 8 above.

12. The experts from IWG SLR and IMMA proposed to amend the inboard visibility angle for rear position lamps in pairs in the new LSD UN Regulation (ECE/TRANS/WP.29/GRE/2018/33 and GRE-80-32). GRE adopted the proposal and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their June 2018 sessions as draft Supplement 1 to the original LSD UN Regulation. GRE also recalled that this modification should be submitted together with the corresponding proposal to amend UN Regulation No. 53 (ECE/TRANS/WP.29/GRE/2018/28), which had been agreed upon at the previous session, and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their June 2019 sessions as draft Supplement 4 to the 02 series and draft Supplement 22 to the 01 series of amendments to UN Regulation No. 53.

13. The expert from IMMA proposed a modification to the presentation on change index (GRE-79-12-Rev.1). GRE adopted the modification and requested the secretariat to publish the revised presentation as a reference document on the GRE website.

14. The expert of SAE presented collective amendments to UN Regulations Nos. 98, 112, 113 and 123 for the purposes of the recently updated Canadian Federal Motor Vehicle Safety Standard (CMVSS) No. 108 (ECE/TRANS/WP.29/GRE/2018/32). GRE adopted the proposals and requested the secretariat to submit them to WP.29 and AC.1 for consideration at their June 2019 sessions as draft Supplement 1 to the new 02 series of amendments of UN Regulation No. 98, draft Supplement 1 to the 02 series of amendments of UN Regulation No. 112, draft Supplement 1 to the 03 series of amendments of UN Regulation No. 113 and draft Supplement 1 to the 02 series of amendments of UN Regulation No. 123.

15. The expert from IMMA proposed amended definitions for UN Regulation No. 53 (ECE/TRANS/WP.29/GRE/2018/35 and GRE-80-05). GRE adopted the proposals and requested the secretariat to submit them to WP.29 and AC.1 for consideration at their June 2019 sessions as draft Supplement 4 to the 02 series of amendments to UN Regulation No. 53.

16. GRE was informed about the progress of the Task Force on Substitutes and Retrofits (TF SR) (GRE-80-23). GRE noted that TF SR had prepared proposals on the use of light emitting diode (LED) substitute light sources for light-signalling applications (see below) and would continue with LED substitutes for front-lighting applications.

17. On behalf of TF SR, the expert from Germany introduced amendment proposals to UN Regulation No. 128 for the use of LED substitute light sources (ECE/TRANS/WP.29/GRE/2018/39) as well as corresponding amendments to the Consolidated Resolution on the common specification of light source categories (R.E.5) (ECE/TRANS/WP.29/GRE/2018/40). GRE adopted the proposals and requested the secretariat to submit them to WP.29 and AC.1 for consideration at their March 2019 sessions as draft Supplement 9 to the original version of UN Regulation No. 128 and as draft amendment 3 to R.E.5. GRE noted that both amendments are part of the same package and should enter into force on the same date.

18. To introduce requirements for LED substitute light sources in the installation UN Regulations, the expert from Germany presented collective amendments to UN Regulations Nos. 48, 53, 74 and 86 (ECE/TRANS/WP.29/GRE/2018/41). The expert from OICA submitted comments (GRE-80-19). GRE adopted the proposals unamended and requested the secretariat to submit them to WP.29 and AC.1 for consideration at their June 2019 sessions as draft Supplement 12 to the 06 series of amendments to UN Regulation No. 48, draft Supplement 4 to the 02 series of amendments to UN Regulation No. 53, draft Supplement 11 to the 01 series of amendments to UN Regulation No. 74 and draft Supplement 2 to the 01 series of amendments of UN Regulation No. 86.

19. The expert from Germany also introduced equivalence criteria for LED substitute light source categories which substitute the corresponding filament light source categories (GRE-80-02), as well as the interlock solution, for the BA15-cap system developed by IEC (GRE-80-03). GRE decided to keep GRE-80-02 as a reference document and took note of GRE-80-03.

20. GRE also considered a parallel proposal by TF SR which introduced requirements for the use of LED substitute light sources in the new LSD UN Regulation (ECE/TRANS/WP.29/GRE/2018/42). GRE adopted the proposal, as amended by Annex III, and requested the secretariat to submit them to WP.29 and AC.1 for consideration at their June 2019 sessions.

21. The expert of SAE delivered a presentation on standardization of technical requirements for forward lighting LED replacement light sources (GRE-80-34) and offered to organize a live demonstration at the next session of GRE. The expert from FIA highlighted the advantages of using LED retrofits for front lighting application of vehicles in use and argued in favour of developing regulations in this area (GRE-80-33). He suggested that TF SR should prepare proposals. In this regard, some GRE experts expressed doubts whether this issue could be solved by UN Regulations and felt that it should be treated within national law. Those experts were also of the view that TF SR should finalize LED substitutes for front-lighting applications and then stop its activities without addressing LED retrofits. GRE decided to revert to this discussion at the next session and requested TF SR to continue its work in the interim.

22. The expert of GTB introduced amendment proposals that modified light source category LR4 in UN Regulation No. 128 and in the Consolidated Resolution R.E.5 (ECE/TRANS/WP.29/GRE/2018/48, ECE/TRANS/WP.29/GRE/2018/49 and Add.1). GRE adopted the proposals and requested the secretariat to submit them to WP.29 and AC.1 for consideration at their March 2019 sessions as draft Supplement 9 to the original version of UN Regulation No. 128 and draft amendment 3 to R.E.5. GRE noted that both amendments are part of the same package and should enter into force on the same date.

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.

26. The expert of GTB reported on the outcome of the Forum on Glare and Visibility that had been organized by GTB on 22 October 2018. GRE noted that all presentations from the Forum would be published on the GRE website and requested IWG SLR to take them into account when considering stage 2 of the SLR process.

33. GRE noted that the Global Forum for Road Traffic Safety (WP.1), at its recent session in September 2018, continued considering the amendment proposals to Article 32 and Chapter II of Annex 5 on lighting and light-signalling (ECE/TRANS/WP.1/2017/1/Rev.1) and is expected to finalize this activity in March 2019. At its next session, GRE may expect an oral report from the WP.1 Secretary.

34. GRE was briefed on the recent developments in field of road safety at the ECE level.

35. GRE noted a request by IWG on the International Whole Vehicle Type Approval (IWVTA) to amend approval numbering in UN Regulations Nos. 37, 99 and 128 to align it with Schedule 4 of the revised 1958 Agreement (ECE/TRANS/WP.29/1139, para. 67). GRE recalled that, at its previous session, it had already adopted the necessary amendments which were subsequently submitted to the November 2018 session of WP.29 as documents ECE/TRANS/WP.29/2018/83, ECE/TRANS/WP.29/2018/89 and ECE/TRANS/WP.29/2018/90.

36. The expert from Germany briefly mentioned draft amendments to the LSD Regulation on the sun load impact (phantom effect) (GRE-80-27) and stated that a formal proposal would be submitted to the next session of GRE.

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.

38. Due to lack of time, GRE decided to consider GRE-80-06 at the next session.

39. GRE noted that Mr. V. Genone (Italy), who had participated in GRE activities since 1984, would no longer attend its sessions, due to his imminent retirement. GRE gave him a standing ovation for his dedication and extensive contributions to the work of GRE and wished him success in the future.

40. The expert from GTB introduced a brainstorming paper on signalling requirements for automated/autonomous vehicles (AVs) (GRE-80-16-Rev.1). The secretariat also informed GRE about the establishment, at the June 2018 session of WP.29, of a new Working Party “Groupe de Rapporteurs pour les Véhicules Autonomes” (GRVA) and that coordination between GRVA and other WP.29 Working Parties (GRs) would be done at the WP.29 level. GRE discussed at length how to pursue considering the signalling requirements for AVs, and came to a conclusion that a task force (TF) would be most appropriate for this purpose. The expert from Germany, who was leading TF SR, also agreed to take the lead in the new TF. The experts from UK, GTB and OICA expressed their support to TF. GRE agreed that TF should evaluate and report on the safety needs for AVs to signal their status and communicate their next intended actions using visual or audible signals or a combination of both.

41. GRE agreed to delete the agenda item on IWVTA and to include a new agenda item on international events in the field of automotive lighting of interest to GRE.

42. In compliance with Rule 37 of the Rules of Procedure (TRANS/WP.29/690 and ECE/TRANS/WP.29/690/Amend.1), GRE called for the election of officers. The representatives of the contracting parties, present and voting, elected unanimously Mr. M. Loccufier (Belgium) as Chair and Mr. D. Rovers (Netherlands) as Vice-Chair for the sessions of GRE scheduled in the year 2019.

1. The Working Party on Lighting and Light-Signalling (GRE) held its eighty-second session from 22 to 25 October 2019 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, ECE/TRANS/WP.29/690/Amends. 1 and 2): Belgium, China, Czechia, Cyprus, Finland, France, Germany, Hungary, India, Italy, Japan, Netherlands, Poland, Republic of Korea, South Africa, Spain, Switzerland, United Kingdom of Great Britain and Northern Ireland. 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), Society of Automotive Engineers (SAE).

2. GRE considered and adopted the agenda (ECE/TRANS/WP.29/GRE/2019/1), as reproduced in GRE-82-01 together with the informal documents distributed during the session. GRE also noted the running order proposed by the Chair (GRE-82-14).

2. GRE considered and adopted the agenda (ECE/TRANS/WP.29/GRE/2019/1), as reproduced in GRE-82-01 together with the informal documents distributed during the session. GRE also noted the running order proposed by the Chair (GRE-82-14).

3. The list of informal documents is contained in Annex I to the session report. The list of GRE informal groups is reproduced in Annex IV to the session report.

4. GRE took note of the highlights of the June 2019 session of WP.29 and the official document submission deadline of 24 January 2020 for the April 2020 session of GRE (GRE-82-19).

5. The Chair recalled that GRE was awaiting further progress of automated/autonomous vehicles to see if their light-signalling functions could become a subject for a new UN Global Technical Regulation (UN GTR).

6. No issues were discussed under this agenda item.

7. The expert from the Informal Working Group Simplification of the Lighting and Light-Signalling Regulations" (IWG SLR) reported on their progress (GRE-82-39). He requested GRE to provide guidance on the future development of UN Regulation No. [149] concerning the light sources and reduction in the number of beams. GRE agreed with the approach envisaged by IWG SLR.

8. GRE was informed that the three new simplified UN Regulations Nos. [148] on Light-Signalling Devices (LSD), [149] on Road Illumination Devices (RID) and [150] on Retro-Reflective Devices (RRD) were expected to enter into force on 15 November 2019. GRE noted that IWG SLR had identified errors inadvertently introduced in the text of the new UN Regulation No. [149] and that a correction had been submitted to the WP.29 session in November 2019 (ECE/TRANS/WP.29/2019/125, GRE-82-02). GRE supported the correction.

9. The expert from IWG SLR introduced corrections of mistakes and omissions in the text of the new UN Regulations Nos. [148], [149] and [150] (ECE/TRANS/WP.29/GRE/2019/24, ECE/TRANS/WP.29/GRE/2019/25 and ECE/TRANS/WP.29/GRE/2019/26). GRE adopted the corrections and mandated the secretariat to submit them to WP.29 and the Administrative Committee (AC.1) for consideration at their March 2020 sessions. GRE also requested the secretariat to verify with the United Nations Office for Legal Affairs (OLA) whether the adopted corrections could be introduced in the form of corrigenda to the original versions of the three new UN Regulations.

11. At the proposal to IWG SLR, GRE adopted further corrections to UN Regulation No. [148] (GRE-82-27, GRE-82-28, GRE-82-29 and Annex II) and requested the secretariat to submit them to WP.29 and AC.1 for consideration at their March 2020 sessions.

12. GRE also noted draft consolidated proposals for amendments to UN Regulation Nos. [148] and [150] (GRE-82-30 and GRE-82-26). The Chair invited GRE experts to review these documents and send their comments to IWG SLR.

13. The expert from Italy proposed to correct a wrong reference in UN Regulation No. [149] (GRE-82-33). GRE adopted the correction (Annex III) and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their March 2020 sessions.

14. GRE recalled that, according to the mandate of IWG SLR, the requirements in the original series of the three new UN Regulations should be totally identical to the requirements in the device UN Regulations which had been frozen in the course of the simplification process. Therefore, GRE was of the view that eventual discrepancies should be corrected by means of supplements or corrigenda to the original series of the new UN Regulations, while substantial changes should only be introduced by the 01 series of amendments and supplements therein.

15. The expert of IWG SLR recalled that, in the course of the SLR process, the device UN Regulation had been “frozen” by introducing new series of amendments which did not require changes in the approval number (TRANS/WP.29/815, para. 82). He requested the secretariat to include a corresponding footnote in the final consolidated versions of the device UN Regulations.

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.

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.

19. The expert from IWG SLR reported on the challenges of implementing the Unique Identifier (UI) in the new simplified UN Regulations (GRE-82-31) in the light of the progress of IWG on Database for the Exchange of Type Approval Documentation (DETA). GRE reiterated its view that for lighting and light-signalling devices, approval markings should be replaced by UI. At the same time, GRE noted that the access rights currently proposed by IWG DETA would not be sufficient for the efficient use of UI for the lighting and light-signalling UN Regulations. GRE mandated IWG SLR and the Chair to bring the specific GRE needs for the DETA access rights to the attention of IWG DETA and WP.29 at their forthcoming sessions in November 2019.

20. The expert from GTB proposed amendments to light source categories L1A/6 and L1B/6 in the Consolidated Resolution on the common specification of light source categories (R.E.5), together with an associated amendment to UN Regulation No. 128 (ECE/TRANS/WP.29/GRE/2019/15, ECE/TRANS/WP.29/GRE/2019/16). GRE adopted both proposals and requested the secretariat to submit them, as appropriate, to WP.29 and AC.1 for consideration at their March 2020 sessions as draft amendment 5 to R.E.5. and Supplement 10 to the original version of UN Regulation No. 128.

21. The expert of the Task Force on Substitutes and Retrofits (TF SR) presented their progress report (GRE-82-17-Rev.2) and sought the consent of GRE for the following activities of TF SR:

• Not include Light Emitting Diode (LED) retrofits in UN Regulation No. 128.
• Make UN Regulation No. 37 performance based and technology neutral by amending its scope to also include other light generating technologies, e.g. LED.
• Allow interchange of light sources in the same category, as approved according to UN Regulation No. 37, independent of the technology used for light generation.

23. The expert of TF SR proposed introducing requirements for LED substitute light sources into the new UN Regulation No. [149] on Road Illumination Devices (RID) (ECE/TRANS/WP.29/GRE/2019/19). GRE adopted the proposal and recalled its general view on amending the three new simplified UN Regulations with substantially new provisions (see para. 14 above). Therefore, GRE decided to postpone the submission of ECE/TRANS/WP.29/GRE/2019/19 to WP.29 and AC.1 and to include it the future 01 series of amendments to UN Regulation No. [149] .

24. GRE recalled that, for UN Regulation No. [148], the new provisions on substitute light sources had already been submitted to the November 2019 sessions of WP.29 and AC.1 as part of draft Supplement 1 to the original series (ECE/TRANS/WP.29/2019/81). Following the same approach, GRE agreed that these provisions should be removed from the original series of UN Regulation No. [148], once the 01 series of amendments is established.

25. GRE addressed a proposal by the expert of TF SR that introduced a new LED substitute light source category H11/LED in R.E.5 (ECE/TRANS/WP.29/GRE/2019/21, GRE-82-03 and GRE-82-12). The experts from France and the United Kingdom expressed concerns about the thermal behaviour of this category. The expert from IEC provided additional explanations (GRE-82-45). Nevertheless, GRE requested TF SR to address the raised issues at its next session on 10 December 2019 and invited all concerned experts to take part in the meeting.

28. The expert from the Special Interest Group (SIG) introduced a new draft series of amendments that defines the switching conditions of dipped-beam and Daytime Running Lamps (DRL) and the variable intensity of rear lamps in conjunction with traffic conditions (ECE/TRANS/WP.29/GRE/2019/20 and GRE-82-07). The experts from Japan and EC proposed to reduce the speed threshold in paragraph 6.2.7.5.1. from 25 to 15 km/h (GRE-82-21). GRE supported this modification.

29. The expert of OICA proposed a new version of paragraph 6.19.7.4. (GRE-82-35-Rev.1) on switching of the rear position lamps together with DRLs. Some experts were of the view that the rear position lamps “shall be on” (i.e. always on) when DRLs are on, while others expressed preference to “may be on”, for the sake of reducing the energy consumption. Having extensively discussed this issue, GRE agreed that the rear position lamps “shall” be on in case of adverse weather conditions, however, the list of such conditions would need to be improved. GRE also noted that the transitional provisions in ECE/TRANS/WP.29/GRE/2019/20 had to be clarified. GRE invited SIG to consider the comments received and to submit a revised document to the next session.

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.

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.

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.

27. The expert from Poland proposed modifications to provisions on the rear registration plate lamps (GRE-82-08). Following a brief exchange of views, GRE invited the expert to submit a formal document for consideration at the next session.

32. On behalf of the Task Force on Electromagnetic Compatibility (TF EMC), the expert for OICA presented their status report (GRE-82-24).

33. The expert from the Netherlands proposed improving the text of paragraph of 3.1.8. (ECE/TRANS/WP.29/GRE/2019/27). GRE adopted this proposal and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their March 2020 sessions as draft Supplement 1 to the 06 series of amendments to UN Regulation No. 10.

34. The expert from India proposed making optional the fitment of front position lamps (ECE/TRANS/WP.29/GRE/2019/18). The experts from France, Germany and the Netherlands were not in a position to support the proposal. The expert from India invited GRE to consider only the modification to paragraph 5.10. in ECE/TRANS/WP.29/GRE/2019/18. Following a brief exchange of views, GRE invited the expert from India to submit a separate document on the issue.

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).

36. The expert from IMMA recalled the requirements on Adaptive Driving Beam (ADB) in UN Regulation No. 48 and proposed similar provisions for amending UN Regulation No. 53 (GRE-82-13, GRE-82-18, GRE-82-46-Rev.1). Following a brief exchange of views, the Chair invited GRE experts to send their comments to IMMA with a view to preparing an official document for consideration at the next session.

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.

38. The expert from Poland proposed to clarify the definition of the “on” time for the case of a group of flashes (GRE-82-09). The expert from GTB pointed out that the GTB Working Group Photometry had recently considered an alternative wording for the same purpose. GRE invited both experts to submit a new proposal to the next session.

39. The expert from GTB proposed corrections (ECE/TRANS/WP.29/GRE/2019/17). GRE supported the amendments but decided to postpone their submission to WP.29 and AC.1, in order to combine them with the results of the discussion reflected in the previous paragraph.

40. GRE was briefed on the activities of IWG on the International Whole Vehicle Type Approval (IWVTA).

41. The Secretary of the Global Forum for Road Traffic Safety (WP.1) reported on the outcome of its session in September 2019. WP.1 had extensively discussed the amendments and decided to resume at the next session with the points (i), (j), (r), (t), 34, 35 and 36 in ECE/TRANS/WP.1/2017/1/Rev.1, and take into account Informal document No. 8 (March 2019), ECE/TRANS/WP.1/2019/10 (submitted by Slovakia) and ECE/TRANS/WP.1/2019/11 (submitted by Laser Europe).

42. He suggested that GRE should appoint a resource person who could participate in WP.1 sessions and would reply to technical questions from WP.1 participants. He also briefed GRE on the WP.1 activity on highly and fully automated vehicles. The Chair recalled the GRE and WP.29 discussions on the signalling requirements for automated/autonomous vehicles (see para. 53 below) and sought the opinion of WP.1 on this matter. To this end, the WP.1 Secretary invited an expert from a contracting party to the Convention on Road Traffic (Vienna, 1968) to submit to the next session of WP.1 in March 2020, a short informal document on the pros and cons of different positions. The expert from Germany volunteered to prepare the paper.

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

44. The secretariat reported that ITC, at its eighty-first session in 2019, had adopted the ITC Strategy until 2030, invited its subsidiary bodies to follow-up by aligning their work with the strategy and requested the secretariat to take the necessary actions to promote the implementation of the strategy (ECE/TRANS/288, paras. 15 (a), (c) and (g)). Furthermore, the Committee had expressed its concern for the limited progress in meeting the Sustainable Development Goal targets on road safety and those of the United Nations Decade of Action for Road Safety (ibid, para. 64) (GRE-82-42).

45. GRE noted that, in order to help countries, particularly new contracting parties, to further implement legal instruments in the area of road safety, the secretariat had prepared the draft ITC Recommendations for Enhancing National Road Safety Systems for comments by the Working Parties. GRE stressed the importance of this document and invited GRE experts to transmit their comments to the secretariat by 5 November 2019 at the latest.

46. Due to lack of time, GRE decided to postpone this issue to the next session.

47. The expert from GTB presented driver assistance projections as a new feature of the adaptive driving beam with the aim to increase driver’s comfort and road safety (GRE-82-40). The presentation was accompanied by a live demonstration of three vehicles equipped with the new feature. To allow for the driver assistance projections, the expert proposed amendments to UN Regulations Nos. 48 and [149] (GRE-82-04, GRE-82-40).

48. GRE welcomed both GTB presentation and demonstration. Several experts were of the view that the new system could bring safety benefits provided that:

• Road projections symbols are standardized (e.g. according to UN Regulation No. 121).
• Road projections symbols do not distract other drivers.

49. The expert from Japan informed GRE about his intention to commission a study on the reaction time when symbols are used. The expert of Finland recalled an ongoing discussion on the field view assistant within the Working Party on General Safety Provisions (GRSG) and called for cooperation between GRE and GRSG. GRE invited GTB to consider the comments made and decided to revert to the issue at the next session.

50. The expert from Poland proposed to add a reference to DRL in paragraph 4.4.1. of UN Regulations No. [148] (GRE-82-10-Rev.1). The expert from IWG SLR stated that this proposal would be included into the consolidated package of amendments to the above UN Regulation.

51. The expert from India proposed deleting the prohibition to use lighting and light-signalling devices other than those prescribed in UN Regulations Nos. 53 and 74 (GRE-82-15). Several experts disagreed with this proposal and therefore GRE did not support it.

52. The secretariat drew the attention of GRE to the fact that the new definition of “External status indicator”, which had been introduced by Supplement 11 to the 06 series of amendments to UN Regulation No. 48 (paragraphs 2.7. and 2.37 of ECE/TRANS/WP.29/2018/84), was left out of Supplement 12 (ECE/TRANS/WP.29/2018/99/Rev.2). GRE requested the secretariat to submit a rectifying document to the March 2020 sessions of WP.29 and AC.1.

53. The secretariat reported on the WP.29 considerations, at its June 2019 session, of the signalling requirements for automated/autonomous vehicles (ECE/TRANS/WP.29/1147, paras. 47–50). GRE noted that WP.29 had not been in a position to reach a common position and had referred this issue to WP.1. GRE noted that the Committee for Coordination of Work (WP.29/AC.2) had invited the WP.29 Working Parties (GRs) to identify their priorities with a view to including them into the Programme of Work of WP.29 (ECE/TRANS/WP.29/2019/1/Rev.1). GRE requested IWG SLR to prepare a draft list of GRE priorities.

55. GRE agreed to keep the same structure of the provisional agenda with the new UN Regulations Nos. [148], [149] and [150] becoming sub-items of item 4.

56. In compliance with Rule 37 of the Rules of Procedure (TRANS/WP.29/690 and ECE/TRANS/WP.29/690/Amend.1), GRE called for the election of officers. The representatives of the contracting parties, present and voting, elected unanimously Mr. M. Loccufier (Belgium) as Chair and Mr. D. Rovers (Netherlands) as Vice-Chair for the sessions of GRE scheduled in the year 2020.
