7. The experts of the Informal Working Group “Simplification of the Lighting and Light-Signalling Regulations” (IWG SLR) reported on their activities (GRE-93-05) and invited GRE to provide guidance whether the transitional provisions from the old series of amendments to UN Regulation No. 48 should be reproduced in the forthcoming new series of amendments, together with its own transitional provisions, or the old transitional provisions could be removed and published in a separate document for reference only. GRE experts expressed a general preference to remove the old transitional provisions. For the sake of following a consistent approach across other UN Regulations and WP.29 Working Parties (GRs), GRE requested its Chair to ask guidance from the Committee for Coordination of Work (AC.2) at its session in November 2026.

8. GRE resumed considering of the principle “prohibited if not allowed” for the lamp installation according to UN Regulation No. 48 and noted a draft paragraph 5.22. being discussed within IWG SLR: “The fitting of any lighting and light-signalling device or function, other than those mentioned in paragraph 6, is prohibited for the purposes of granting a type-approval according to this Regulation”. The expert from OICA proposed to add several exceptions to this draft paragraph (GRE-93-21). Following a short discussion, GRE requested IWG SLR to continue consideration and invited all GRE experts to provide their contributions.

9. GRE recalled the package of amendment proposals to UN Regulations Nos. 148, 149 and 150 that had been submitted by the expert from Netherlands (Kingdom of the) with the aim to take onboard the recent amendments to Schedule 5 of the 1958 Agreement on the Unique Identifier (UI) (GRE-92-13, GRE-92-14, GRE-92-15, GRE-92-16, GRE-92-17, GRE-92-18). GRE adopted these proposals and decided to merge them with other possible amendment proposals to the same series of amendments before submitting to WP.29.
