For a more efficient discussion during the 83rd session of GRE the experts from the International Organization of Motor Vehicle Manufacturers merged documents GRE/2020/08-Rev.1 (SLR) and GRE/2020/23 into one document.

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.

Proposal to minimize hazards to other traffic users such as glare and distraction by expanding the scope of the vehicle’s conditions subject to technical requirements under “normal conditions of use” (para. 5.1.), including use of lighting when parked or engine stopped.

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.

Proposal to introduce new requirements for headlamp levelling, in particular on the vertical inclination in relation to the dipped-beam headlamp mounting height.

Proposal to define the switching conditions of dipped beam and daytime running lamps (DRL) and the variable intensity of rear lamps in conjunction with traffic conditions.

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).

25. The expert from IWG SLR proposed several corrections (ECE/TRANS/WP.29/GRE/2020/24 and GRE-83-06). GRE adopted these proposals and requested the secretariat to submit them for consideration and vote at the March 2021 sessions of WP.29 and AC.1 as draft Supplement 14 to the 06 series of amendments and draft Supplement 1 to the 07 series of amendments to UN Regulation No. 48.
