28. The experts from Germany briefed GRE on the outcome of a study on dynamic levelling devices to prevent headlamp glare (GRE-83-03 and Add.1).

29. Based on a proposal of IWG SLR, GRE continued its deliberations for preparing a new series of amendments to UN Regulation No. 48 with new requirements for headlamp aiming and automatic levelling (ECE/TRANS/WP.29/GRE/2020/8/Rev.1). The expert from Poland held the view that the justification part contained mistakes and inconsistencies and recalled his earlier proposals on the subject (GRE-83-41). Several experts expressed their support to the IWG SLR proposal.

30. The expert from OICA proposed to keep an option of manual levelling (ECE/TRANS/WP.29/GRE/2020/23 and GRE-83-31). Some experts supported this option, while others were not in favour.

31. In the absence of a consensus, GRE stressed the need to finalize the issue as soon as possible and requested IWG SLR to take into account the comments made and to prepare a revised working document for the next session, based on the following principles:

• the aiming diagram agreed at the eighty-first session of GRE (Annex II to ECE/TRANS/ WP.29/GRE/81);
• automatic levelling;
• manual levelling, only if a consensus is reached within IWG SLR.

33. GRE instructed IWG SLR to organize a separate meeting on this issue and encouraged all experts of Contracting Parties to participate.

34. The expert from the Special Interest Group (SIG) presented a proposal for another new draft series of amendments to UN Regulation No. 48 concerning switching conditions of various lamps and the variable intensity of rear lamps in conjunction with traffic conditions (ECE/TRANS/WP.29/GRE/2020/14). The expert from OICA proposed further modifications (GRE-83-32). Following an in-depth discussion, GRE invited SIG to take into account various comments and to submit a revised document to the next session.

35. GRE noted GRE-83-45 submitted by the experts from Japan and invited them to submit an official document to the next session. In the interim, the Chair suggested that IWG SLR should also consider this proposal.
