16. The expert from OICA introduced a proposal that aimed to delete the current 2 m width requirement for parking lamps (ECE/TRANS/WP.29/GRE/2025/4 and GRE-92-31). GRE adopted the proposal and requested the secretariat to submit it for consideration and adoption to the November 2025 sessions of WP.29 and the Administrative Committee (AC.1) as draft Supplement 22 to the 06 series, draft Supplement 9 to the 07 series, draft Supplement 7 to the 08 series and draft Supplement 2 to the 09 series of amendments to UN Regulation No. 48. GRE noted that the Vienna Convention (1968) would need to be aligned with the adopted proposal. GRE agreed to contact the Global Forum for Road Traffic Safety (WP.1) ant its secretariat with the aim to identify the proper procedure for amending the Vienna Convention.
17. The expert from OICA introduced draft amendments that permitted the installation of an optional rear mounted manoeuvring lamp (ECE/TRANS/WP.29/GRE/2025/5). GRE adopted the proposal, as amended by GRE-92-10-Rev.1 and requested the secretariat to submit it for consideration and adoption to the November 2025 sessions of WP.29 and AC.1 as part of draft Supplement 2 to the 09 series of amendments to UN Regulation No. 48.
18. The experts from GTB proposed allowing the installation of side-marker lamps combined with retro-reflectors on the lateral foremost position on semi-trailers (ECE/TRANS/WP.29/GRE/2025/6). GRE adopted the proposal and requested the secretariat to submit it for consideration and adoption to the November 2025 sessions of WP.29 and AC.1 as part of draft Supplement 22 to the 06 series, draft Supplement 9 to the 07 series, draft Supplement 7 to the 08 series and draft Supplement 2 to the 09 series of amendments to UN Regulation No. 48.
19. The experts from GTB proposed clarifying the duration of the optical indication of the answer-back signal (ECE/TRANS/WP.29/GRE/2025/7). GRE adopted the proposal and requested the secretariat to submit it for consideration and adoption to the November 2025 sessions of WP.29 and AC.1 as part of draft Supplement 2 to the 09 series of amendments to UN Regulation No. 48.
23. The expert from GTB presented revised amendment proposals that introduced reversing projections in UN Regulations No. 148 and 48 (ECE/TRANS/WP.29/GRE/2024/20/Rev.1), as well as supporting statistical data (GRE-92-04). One expert believed that the accompanying statistical data did not provide sufficient evidence for road safety benefits of reversing projections. GRE suggested an improvement to the provision that the reversing projection should not negatively affect rear camera system performance as defined in UN Regulation No. 158. Finally, GRE adopted the proposals, as amended by GRE-92-32, and requested the secretariat to submit it for consideration and adoption to the November 2025 sessions of WP.29 and AC.1 as part of draft Supplement 22 to the 06 series, draft Supplement 9 to the 07 series, draft Supplement 7 to the 08 series and draft Supplement 2 to the 09 series of amendments to UN Regulation No. 48, as well as draft Supplement 5 to the 01 series of amendments to UN Regulation No. 148. GRE also agreed to inform the Working Party on General Safety Provisions (GRSG) about these amendment proposals, as they mention UN Regulation No. 158 which is within the scope of GRSG.
