14. The expert from IWG SLR tabled a revised proposal for a new series of amendments to UN Regulation No. 48 that introduces new requirements for headlamp levelling and allows manual levelling only for off-road vehicles (ECE/TRANS/WP.29/GRE/2020/8/Rev.2). The expert from Poland suggested amendments for the initial downward inclination (GRE-84-37). The experts from France and the United Kingdom of Great Britain and Northern Ireland made further comments.

15. GRE noted diverging positions on the proposed aiming diagram and manual levelling for off-road vehicles. GRE remained optimistic that a consensus could be reached and requested IWG SLR to convene 1-2 additional separate meetings with the aim to reconcile the different positions and to prepare a revised proposal for the next session.

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.

28. GRE noted that so far IWG SLR had not been able to reconcile different positions on the proposal for headlamp levelling (ECE/TRANS/WP.29/GRE/2020/8/Rev.2, GRE-85-19, GRE-85-29) and decided to revert to this issue at the next session.
