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.

8. On behalf of the Informal Working Group on Simplification of the Lighting and Light-Signalling Regulations (IWG SLR), the expert from GTB reported on the finalization of stage 1 of SLR (GRE-79-28). He further provided a draft schedule for stage 2 which would include two steps. Step 1 would cover objectives which could be achieved by the end of 2019, such as introducing technology neutral and performance based requirements, as well as objectively testable provisions. Step 2 would start in 2020 with the aim to simplify the installation Regulations Nos. 48, 53, 74 and 86. As an additional task, he suggested harmonization with the applicable standards in China. GRE experts also proposed other issues for stage 2 of SLR.

9. The expert from GTB presented the full package of amendment proposals drafted by IWG SLR under stage 1 of SLR:

a) The three new simplified UN Regulations on Light-Signalling Devices (LSD), Road Illumination Devices (RID) and Retro-Reflective Devices (RRD) (ECE/TRANS/WP.29/GRE/2018/2, ECE/TRANS/WP.29/GRE/2018/3, ECE/TRANS/WP.29/GRE/2018/4, GRE-79-10 and GRE-79-14);

b) Draft amendments to Regulations Nos. 48, 53, 74 and 86 that group the definitions and introduce references to the new simplified Regulations (ECE/TRANS/WP.29/GRE/2018/6, ECE/TRANS/WP.29/GRE/2018/7, ECE/TRANS/WP.29/GRE/2018/8, ECE/TRANS/WP.29/GRE/2018/9, ECE/TRANS/WP.29/GRE/2018/10, ECE/TRANS/WP.29/GRE/2018/12, ECE/TRANS/WP.29/GRE/2018/13, ECE/TRANS/WP.29/GRE/2018/14, ECE/TRANS/WP.29/GRE/2018/15, ECE/TRANS/WP.29/GRE/2018/17, ECE/TRANS/WP.29/GRE/2018/30, GRE-79-08, GRE-79-09 and GRE-79-13);

c) Transitional provisions to “freeze” 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).

10. The expert from EC was not in a position to support the indefinite validity of type approvals granted under the frozen Regulations, as proposed in ECE/TRANS/WP.29/GRE/2018/11, because of the General Safety Regulation of the European Union. He proposed revised transitional provisions for these Regulations (GRE-79-31, part I), together with new transitional provisions for the installation Regulations Nos. 48, 53, 74 and 86 (GRE-79-31, part II). While several experts agreed in principle with part I, they were not in a position to support part II. The experts from Finland and UK made study reservations. The expert from OICA expressed the concern that the revised transitional provisions might be rejected by WP.29.

11. To not delay the submission of the whole package of amendment proposals that had been developed in stage 1 of SLR, GRE decided to provisionally adopt the transitional provisions in ECE/TRANS/WP.29/GRE/2018/11, but to put in square brackets the third transitional provision for each Regulation mentioned in the document. At the same time, GRE recognized the urgency of the issue raised by the expert from EC and requested all GRE experts, as well as IWG SLR, to carefully consider the EC proposals with a view to taking a final position at the next session.

12. The expert from IWG SLR proposed correcting minor errors and inconsistencies identified in the documents mentioned under para. 9 (a) above (GRE-79-14). GRE adopted these corrections, as laid down in Annex II.

13. The expert from IWG SLR also suggested rectifying minor errors and inconsistencies in the documents listed in para. 9 (b) above (GRE-79-13). GRE adopted these corrections, as laid down in Annex III, and decided to opt for the alternative wording (in square brackets) of paragraph 6.3.9. of different series of amendments to Regulation No. 48.

14. The expert from India suggested corrections to ECE/TRANS/WP.29/GRE/2018/2 and ECE/TRANS/WP.29/GRE/2018/3 (GRE-79-17-Rev.1 and GRE-79-18-Rev.1 new text). GRE adopted the corrections, as laid down in Annexes IV and V. The expert from India withdrew GRE-79-19, in order to first present it at the next session of IWG SLR.

15. The expert from IWG SLR recalled that all identical definitions should only be kept in Regulation No. 48. Thus, he proposed to review the definitions in Regulations Nos. 53 and 74 (GRE-79-08 and GRE-79-09, respectively). GRE adopted these modifications, as contained in Annex VI.

16. The expert from IWG SLR presented the concept of “change index” developed for the LSD, RID and RRD Regulations (GRE-79-12-Rev.1). He further introduced amendment proposals on the change index to Regulations Nos. 48, 53, 74 and 86 (ECE/TRANS/WP.29/GRE/2018/16, ECE/TRANS/WP.29/GRE/2018/18 and GRE-79-11). GRE adopted these proposals, as amended by Annex VII). In addition, GRE agreed to include transitional provisions on the change index in the text of the LSD, RID and RRD Regulations (GRE-79-10 and Annex VIII). The expert from India pointed out that he would refer GRE-79-22 to IWG SLR.

17. Subject to the modifications mentioned in paras. 10–16 above, GRE adopted the package of amendment proposals drafted by IWG SLR and listed in para. 9 a) – c). The secretariat was requested to submit the amendments proposals to WP.29 and to the Administrative Committee of the 1958 Agreement (AC.1) for consideration and vote at their November 2018 sessions. GRE noted that any modification of the transitional provisions, mentioned in para. 11 above, that GRE might agree upon at the next GRE session in October 2018, would be submitted to the November 2018 session of WP.29 as corrigenda to the basic SLR package which otherwise would be issued in August 2018.

18. The expert of SAE proposed to keep Regulations Nos. 98, 112, 113 and 123 “alive” for the purpose of the recently updated Canadian Federal Motor Vehicle Safety Standard (CMVSS) No. 108 (GRE-79-32-Rev.1). GRE referred this document to IWG SLR for consideration.

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.

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.

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.

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.

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.

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.

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.

69. The World Forum considered the draft amendments under agenda items 4.6.1 to 4.6.15 and recommended their submission to AC.1 for voting, subject to the following modifications:

• Item 4.6.3, document ECE/TRANS/WP.29/2019/81, last page, Table A2-1, line “Rear position pair (MR)”, replace “15°/15°” with “15°/10°”.
• Item 4.6.5, document ECE/TRANS/WP.29/2019/125, amend the title to read “Supplement 1 to the original series of UN Regulation No. [149] on Road Illumination Devices (RID)”.

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.

69. The World Forum considered the draft amendments under agenda items 4.6.1 to 4.6.15 and recommended their submission to AC.1 for voting, subject to the following modifications:

• Item 4.6.3, document ECE/TRANS/WP.29/2019/81, last page, Table A2-1, line “Rear position pair (MR)”, replace “15°/15°” with “15°/10°”.
• Item 4.6.5, document ECE/TRANS/WP.29/2019/125, amend the title to read “Supplement 1 to the original series of UN Regulation No. [149] on Road Illumination Devices (RID)”.

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.

12. The expert from GTB presented proposals for amendments to Regulation No. 128 and to the Consolidated Resolution (R.E.5) which introduce requirements and test specifications for light emitting diode (LED) substitute light sources as well as several new LED substitute light source categories (ECE/TRANS/WP.29/GRE/2017/2, ECE/TRANS/WP.29/GRE/2017/3, GRE-77-02, GRE-77-03, GRE-77-15, GRE-77-22). These proposals were accompanied by collective amendments to Regulations Nos. 48, 53, 74, 86 with the requirements for LED substitute light sources (ECE/TRANS/WP.29/GRE/2017/4). The expert from GTB explained that the proposed approach was based on the following principles:

• Lamps may be approved with a filament light source and its corresponding LED substitute light source, when fitting in the same holder, and providing an equivalent photometric performance;
• Lamps equipped with LED substitute light sources should be tested with both the filament lamp and the LED substitute light source.

13. GRE also noted the proposal by GTB to introduce requirements for the use of LED substitute light sources in the new LSD Regulation (GRE-77-15).

14. Pending the outcome of the discussion on light emitting diode (LED) substitute light sources (see agenda item 5, paras. 17-19), GRE agreed to postpone consideration of ECE/TRANS/WP.29/GRE/2017/14, ECE/TRANS/WP.29/GRE/2017/15 and GRE-78-04.

8. On behalf of the Informal Working Group on Simplification of the Lighting and Light-Signalling Regulations (IWG SLR), the expert from GTB reported on the finalization of stage 1 of SLR (GRE-79-28). He further provided a draft schedule for stage 2 which would include two steps. Step 1 would cover objectives which could be achieved by the end of 2019, such as introducing technology neutral and performance based requirements, as well as objectively testable provisions. Step 2 would start in 2020 with the aim to simplify the installation Regulations Nos. 48, 53, 74 and 86. As an additional task, he suggested harmonization with the applicable standards in China. GRE experts also proposed other issues for stage 2 of SLR.

9. The expert from GTB presented the full package of amendment proposals drafted by IWG SLR under stage 1 of SLR:

a) The three new simplified UN Regulations on Light-Signalling Devices (LSD), Road Illumination Devices (RID) and Retro-Reflective Devices (RRD) (ECE/TRANS/WP.29/GRE/2018/2, ECE/TRANS/WP.29/GRE/2018/3, ECE/TRANS/WP.29/GRE/2018/4, GRE-79-10 and GRE-79-14);

b) Draft amendments to Regulations Nos. 48, 53, 74 and 86 that group the definitions and introduce references to the new simplified Regulations (ECE/TRANS/WP.29/GRE/2018/6, ECE/TRANS/WP.29/GRE/2018/7, ECE/TRANS/WP.29/GRE/2018/8, ECE/TRANS/WP.29/GRE/2018/9, ECE/TRANS/WP.29/GRE/2018/10, ECE/TRANS/WP.29/GRE/2018/12, ECE/TRANS/WP.29/GRE/2018/13, ECE/TRANS/WP.29/GRE/2018/14, ECE/TRANS/WP.29/GRE/2018/15, ECE/TRANS/WP.29/GRE/2018/17, ECE/TRANS/WP.29/GRE/2018/30, GRE-79-08, GRE-79-09 and GRE-79-13);

c) Transitional provisions to “freeze” 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).

10. The expert from EC was not in a position to support the indefinite validity of type approvals granted under the frozen Regulations, as proposed in ECE/TRANS/WP.29/GRE/2018/11, because of the General Safety Regulation of the European Union. He proposed revised transitional provisions for these Regulations (GRE-79-31, part I), together with new transitional provisions for the installation Regulations Nos. 48, 53, 74 and 86 (GRE-79-31, part II). While several experts agreed in principle with part I, they were not in a position to support part II. The experts from Finland and UK made study reservations. The expert from OICA expressed the concern that the revised transitional provisions might be rejected by WP.29.

11. To not delay the submission of the whole package of amendment proposals that had been developed in stage 1 of SLR, GRE decided to provisionally adopt the transitional provisions in ECE/TRANS/WP.29/GRE/2018/11, but to put in square brackets the third transitional provision for each Regulation mentioned in the document. At the same time, GRE recognized the urgency of the issue raised by the expert from EC and requested all GRE experts, as well as IWG SLR, to carefully consider the EC proposals with a view to taking a final position at the next session.

12. The expert from IWG SLR proposed correcting minor errors and inconsistencies identified in the documents mentioned under para. 9 (a) above (GRE-79-14). GRE adopted these corrections, as laid down in Annex II.

13. The expert from IWG SLR also suggested rectifying minor errors and inconsistencies in the documents listed in para. 9 (b) above (GRE-79-13). GRE adopted these corrections, as laid down in Annex III, and decided to opt for the alternative wording (in square brackets) of paragraph 6.3.9. of different series of amendments to Regulation No. 48.

14. The expert from India suggested corrections to ECE/TRANS/WP.29/GRE/2018/2 and ECE/TRANS/WP.29/GRE/2018/3 (GRE-79-17-Rev.1 and GRE-79-18-Rev.1 new text). GRE adopted the corrections, as laid down in Annexes IV and V. The expert from India withdrew GRE-79-19, in order to first present it at the next session of IWG SLR.

15. The expert from IWG SLR recalled that all identical definitions should only be kept in Regulation No. 48. Thus, he proposed to review the definitions in Regulations Nos. 53 and 74 (GRE-79-08 and GRE-79-09, respectively). GRE adopted these modifications, as contained in Annex VI.

16. The expert from IWG SLR presented the concept of “change index” developed for the LSD, RID and RRD Regulations (GRE-79-12-Rev.1). He further introduced amendment proposals on the change index to Regulations Nos. 48, 53, 74 and 86 (ECE/TRANS/WP.29/GRE/2018/16, ECE/TRANS/WP.29/GRE/2018/18 and GRE-79-11). GRE adopted these proposals, as amended by Annex VII). In addition, GRE agreed to include transitional provisions on the change index in the text of the LSD, RID and RRD Regulations (GRE-79-10 and Annex VIII). The expert from India pointed out that he would refer GRE-79-22 to IWG SLR.

17. Subject to the modifications mentioned in paras. 10–16 above, GRE adopted the package of amendment proposals drafted by IWG SLR and listed in para. 9 a) – c). The secretariat was requested to submit the amendments proposals to WP.29 and to the Administrative Committee of the 1958 Agreement (AC.1) for consideration and vote at their November 2018 sessions. GRE noted that any modification of the transitional provisions, mentioned in para. 11 above, that GRE might agree upon at the next GRE session in October 2018, would be submitted to the November 2018 session of WP.29 as corrigenda to the basic SLR package which otherwise would be issued in August 2018.

18. The expert of SAE proposed to keep Regulations Nos. 98, 112, 113 and 123 “alive” for the purpose of the recently updated Canadian Federal Motor Vehicle Safety Standard (CMVSS) No. 108 (GRE-79-32-Rev.1). GRE referred this document to IWG SLR for consideration.

20. On behalf of the Task Force on LED retrofits and substitutes (TF SR), the expert from Germany presented their status report (GRE-79-16). GRE supported the proposed two-step approach and mechanical interlock as a solution to avoid misuse of light emitting diode (LED) substitutes.

21. GRE recalled the earlier proposals by GTB to introduce LED substitutes and replaceable light sources into the new LSD and RID Regulations (ECE/TRANS/WP.29/GRE/2017/14, ECE/TRANS/WP.29/GRE/2017/15 and GRE-78-04) and noted that ECE/TRANS/WP.29/GRE/2017/15 had been incorporated in ECE/TRANS/WP.29/GRE/2018/3. GRE invited TF SR to update ECE/TRANS/WP.29/GRE/2017/14 and GRE-78-04.

22. The expert from GTB pointed out that the GTB guidelines for introducing and evaluating LED light source categories that were intended for forward lighting applications (GRE-77-04) should be published as a reference document on the GRE website. GRE agreed to this request.

69. The World Forum considered the draft amendments under agenda items 4.6.1 to 4.6.15 and recommended their submission to AC.1 for voting, subject to the following modifications:

• Item 4.6.3, document ECE/TRANS/WP.29/2019/81, last page, Table A2-1, line “Rear position pair (MR)”, replace “15°/15°” with “15°/10°”.
• Item 4.6.5, document ECE/TRANS/WP.29/2019/125, amend the title to read “Supplement 1 to the original series of UN Regulation No. [149] on Road Illumination Devices (RID)”.

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.

28. The expert from Japan introduced a proposal for the 03 series of amendments to Regulation No. 53 with a new requirement for automatic switching from the daytime running lamp (DRL) to the headlamp (ECE/TRANS/WP.29/GRE/2016/35, Informal document GRE-76-03). The experts of Finland, Germany and EC supported the proposal. The experts of France, Italy and UK identified technical issues which would need further attention. GRE agreed to revert to this issue at the next session. GRE also noted proposals by the expert from India (GRE-76-06). GRE invited experts to review these proposals and to send their comments to the author before the next session.

7. On behalf of the Informal Working Group ‘Simplification of the Lighting and Light-Signalling Regulations’ (IWG SLR), the expert from GTB reported on the progress and schedule of IWG SLR (GRE-78-34) in preparing the three new simplified UN Regulations on Light-Signalling Devices (LSD), Road Illumination Devices (RID) and Retro-Reflective Devices (RRD). He presented a draft LSD Regulation (ECE/TRANS/WP.29/GRE/2017/9), amendments to Regulations Nos. 48, 53, 74 and 86 that group the definitions and introduce references to the new simplified Regulations (ECE/TRANS/WP.29/GRE/2017/10, ECE/TRANS/WP.29/GRE/2017/11, GRE-78-11, GRE-78-12, GRE-78-13, GRE-78-14, GRE-78-15 and GRE-78-20), and the new transitional provisions to 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/2017/13). The expert from India commented on the IWG SLR proposals (GRE-78-26).

8. GRE agreed that the new UN Regulations and the necessary amendments to the existing Regulations should be adopted as a package, possibly at the next session. GRE was of the view that all definitions should be moved to one place and that Regulation No. 48 would be the best choice for that purpose, in spite of the fact that not all Contracting Parties to the 1958 Agreement applied this Regulation. GRE also agreed, in principle, that the transitional period to start the application of the new UN Regulations should be twenty-four months, as proposed by IWG SLR in the draft transitional provisions. GRE decided to revert to this issue once the timeline for the entry into force of the new UN Regulations was known, and which depends on IWG SLR progress.

9. The expert from Germany drew the attention of GRE to the non-availability of the electronic database for the exchange of type approval documentation (DETA) and the Unique Identifier (UI) at the time of the entry into force of the new UN Regulations (GRE-78-27). This might create difficulties for applying approval markings and would make the full benefits of SLR impossible to reap. GRE agreed that the new UN Regulations should include a substitute solution of quasi-traditional approval markings pending the availability of UI.

10. On behalf of IWG SLR, the expert of GTB presented a new concept of “change index” which aims to adapt and simplify the traditional approval markings in the context of the new LSD Regulation (GRE-78-35 and Rev.1). In particular, he proposed a table that lists all devices covered by the LSD Regulation and indicates the series of amendments with the most stringent requirements for each device. Following an in-depth discussion, GRE felt that having in the approval marking both series of amendments and a change index would be superfluous. A number of experts spoke in favour of indicating the series of amendments only, preceded by the Regulation number. The expert from UK pointed out the need to study how the proposed solution would work for extension of type approvals. The Chair requested IWG SLR to address this issue and invited the expert from UK to contribute.

11. GRE requested IWG SLR to consult the European Committee of Associations of Manufacturers of Agricultural Machinery (CEMA) about the draft amendments to Regulation No. 86. GRE also noted that IWG SLR would consult the IWG on the International Whole Vehicle Type Approval (IWVTA) about the approval markings for the new LSD Regulation.

34. On behalf of the Special Interest Group for DRL of L-category vehicles, the expert from Japan proposed a new requirement for automatic switching from DRL to the headlamp for L3 category (ECE/TRANS/WP.29/GRE/2018/19). The expert from India suggested deletion of the wording “passing beam” from the text (GRE-79-20). Some GRE experts supported in principal ECE/TRANS/WP.29/GRE/2018/19, but expressed concerns about the proposed introduction of a new category of daytime running lamps with the maximum luminous intensity of 700 cd. GRE invited experts to send their comments to the Special Interest Group and agreed to continue consideration of the proposal at the next session.

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.

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.

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.

69. The World Forum considered the draft amendments under agenda items 4.6.1 to 4.6.15 and recommended their submission to AC.1 for voting, subject to the following modifications:

• Item 4.6.3, document ECE/TRANS/WP.29/2019/81, last page, Table A2-1, line “Rear position pair (MR)”, replace “15°/15°” with “15°/10°”.
• Item 4.6.5, document ECE/TRANS/WP.29/2019/125, amend the title to read “Supplement 1 to the original series of UN Regulation No. [149] on Road Illumination Devices (RID)”.
