17. The expert from OICA proposed aligning the requirement for the visibility of red light towards the front and/or white light toward the rear of the vehicle in various series of amendments to UN Regulation No. 48 with the 01 series of amendments to UN Regulations Nos.148 and 149 (GRE-88-17 and GRE-88-18).

18. GRE adopted GRE-88-18 and decided to include it in a new 09 series of amendments to UN Regulation No. 48. GRE also adopted GRE-88-17 as a Supplement to the series of amendments from 03 to 08 of UN Regulation No. 48. GRE requested the secretariat to submit it for consideration and vote at the November 2023 sessions of WP.29 and AC.1 as part of draft Supplement 19 to the 06 series of amendments, draft Supplement 6 to the 07 series of amendments and draft Supplement 4 to the 08 series of amendments to UN Regulation No. 48. GRE decided to postpone the submission of these amendments for the 03, 04 and 05 series of amendments, in order to combine them with future amendment proposals to the same series of amendments.

21. The Chair summarized that the following draft amendments were adopted at this session and would become part of the draft 09 series of amendments to UN Regulation No. 48:

1. Headlamp levelling (paragraph 8 above);
2. Device transition (paragraph 11);
3. Park condition (paragraph 19);
4. Manoeuvring lamps on trailers (paragraph 16);
5. Visibility of red light towards the front and/or white light toward the rear (paragraph 18); and
6. Transitional provisions (paragraph 20).

22. GRE decided to submit the above proposals for consideration and vote at the March 2024 sessions of WP.29 and AC.1 as a new 09 series of amendments to UN Regulation No. 48. At its next session in October 2023, GRE agreed to editorially confirm these proposals without modifying their substantial content and requirements. To this end, GRE suggested that a consolidated text of the draft 09 series of amendments to UN Regulation No. 48 be prepared.

39. GRE recalled that, at its present and previous sessions, it had adopted GRE-88-17 and ECE/TRANS/WP.29/GRE/2023/13 as a Supplement to the 03, 04 and 05 series of amendments to UN Regulation No. 48 but had decided to postpone the submission of these amendments to WP.29, in order to combine them with future amendment proposals to the same series of amendments.

27. GRE recalled that, at its previous sessions, it had adopted several amendments but had decided to postpone their submission to WP.29, in order to combine them with future amendment proposals to the same UN Regulation and series of amendments. In view of amendment proposals adopted at this session, GRE agreed to proceed as follows:

• Submit GRE-88-17 and ECE/TRANS/WP.29/GRE/2023/13 for consideration and vote at the March 2025 sessions of WP.29 and AC.1 as draft Supplement 10 to the 03 series, draft Supplement 23 to the 04 series and draft Supplement 18 to the 05 series of amendments to UN Regulation No. 48,
• Submit ECE/TRANS/WP.29/GRE/2024/3 for consideration and vote at the March 2025 sessions of WP.29 and AC.1 as part of draft Supplement 21 to the 06 series, draft Supplement 8 to the 07 series, draft Supplement 6 to the 08 series and draft Supplement 1 to the 09 series of amendments to UN Regulation No. 48,
• Submit ECE/TRANS/WP.29/GRE/2024/4 for consideration and vote at the March 2025 sessions of WP.29 and AC.1 as part of draft Supplement 21 to the 06 series, draft Supplement 8 to the 07 series, draft Supplement 6 to the 08 series and draft Supplement 1 to the 09 series of amendments to UN Regulation No. 48,
• Submit GRE-90-10 for consideration and vote at the March 2025 sessions of WP.29 and AC.1 as part of draft Supplement 1 to the 09 series of amendments to UN Regulation No. 48, and
• At its next session in April 2025, decide on the submission of GRE-90-36 as a Supplement to the 06 series of amendments to UN Regulation No. 10.

12. The expert from Germany tabled a proposal to clarify that only light-signalling devices may incorporate an illuminated manufacturer logo (ECE/TRANS/WP.29/GRE/2024/13 and GRE-91-24), meaning that such logos would be prohibited for road illumination devices and retro-reflectors. GRE experts generally supported the proposal and suggested modifications to the text. The expert from OICA hold the view that the prohibition could lead to problems with existing lamps and, thus, should be introduced by a new series of amendments with transitional provisions.

13. Following an in-depth discussion, GRE realized that fine tuning of the text would require more time and agreed to continue consideration at the next session. Meanwhile, GRE urged type approval authorities to refrain from granting type approvals to road illumination devices and retro-reflectors with illuminated manufacturer logos.
