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.

32. The expert from Poland did not agree to that conclusion.

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