8. GRE noted the progress of the Informal Working Group “Simplification of the Lighting and Light-Signalling Regulations” (IWG SLR) (GRE-86-07). The expert of IWG SLR proposed amendments to the work plan and time schedule as contained in the Terms of Reference (GRE-86-06). GRE adopted these modifications, as contained in Annex III of the session report, and extended the IWG SLR mandate until December 2025.

15. The expert of IWG SLR reported on their work on a new series of amendments to UN Regulation No. 48 that introduces new requirements for headlamp levelling (GRE-86-07). GRE noted that IWG SLR was collecting anonymous vehicle levelling data for type approval and for conformity of production, with the aim to prepare an informal proposal for the GRE session in October 2022 and a formal document for the GRE session in April 2023. The expert from IWG SLR also invited those experts, who were not in a position to support the aiming diagram in ECE/TRANS/GRE/2020/8/Rev.2, to submit concrete alternative proposals for consideration.
