7. GRE noted the progress of the Informal Working Group “Simplification of the Lighting and Light-Signalling Regulations” (IWG SLR) (GRE-89-07).

8. The expert of IWG SLR proposed to correct a reference to UN Regulation No. 148 in UN Regulation No. 48 (ECE/TRANS/WP.29/GRE/2023/13). GRE adopted the proposal and requested the secretariat to submit it for consideration and vote at the March 2024 sessions of WP.29 and the Administrative Committee (AC.1) as draft Supplement 20 to the 06 series of amendments, draft Supplement 7 to the 07 series of amendments, draft Supplement 5 to the 08 series of amendments and part of the draft new 09 series of amendments to UN Regulation No. 48. GRE also adopted this proposal as draft Supplements to the 03, 04 and 05 series of amendments to UN Regulation No. 48 but decided to keep them as pending for the time being, in order to combine them with other amendment proposals to the same series of amendments.

9. The expert of IWG SLR tabled proposals that clarified and corrected the text of various series of amendments to UN Regulation Nos. 148 and 150 (ECE/TRANS/WP.29/GRE/2023/14 and ECE/TRANS/WP.29/GRE/2023/16, respectively). GRE adopted these proposals and requested the secretariat to submit them for consideration and vote at the March 2024 sessions of WP.29 and AC.1 as draft Supplement 2 to the 01 series of amendments to UN Regulation No. 148, draft Supplement 6 to the 00 series of amendments and draft Supplement 2 to the 01 series of amendments to UN Regulation No. 150.

10. The expert of IWG SLR also introduced proposals that clarified and corrected the text of the 00 and 01 series of amendments to UN Regulation No. 149 (ECE/TRANS/WP.29/GRE/2023/15). GRE agreed that the amended paragraph 3.2.2. from the 00 series amendments (part A of the document) should also be included in the 01 series of amendments (part B). Subject to this modification, GRE adopted the proposals and requested the secretariat to submit them for consideration and vote at the March 2024 sessions of WP.29 and AC.1 as draft Supplement 8 to the 00 series of amendments and draft Supplement 3 to the 01 series of amendments to UN Regulation No. 149.

11. The expert of IWG SLR proposed to amend paragraph 6.2.8.2. of UN Regulation No. 48 with technology neutral failure provisions (GRE-89-04). GRE adopted the proposal and agreed to merge it with the draft 09 series of amendments to UN Regulation No. 48.

12. GRE recalled its previous discussions on use of the Unique Identifier (UI) in the UN Regulations under GRE purview. The expert of IWG SLR presented their conclusion that UI would be needed for UN Regulations Nos. 65, 148, 149 and 150, while consensus was not found for UN Regulation No. 45 (GRE-89-03). The expert from CITA shared his thoughts on how the concept of UI could function in practice (GRE-89-11). In his view, UI would be required for UN Regulation No. 65 and possibly for UN Regulations Nos. 148, 149 and 150, if the space available on the products would not be sufficient for engraving traditional approval markings. GRE also took note that other WP.29 Working Parties (GRs) were not in favour of using UI in their UN Regulations.
