Proposal concerning the conditions under which the vehicles may circulate with the dipped beam headlamps switched OFF from the SLR informal group to based on document ECE/TRANS/WP.29/GRE/2019/03 taking into account the agreed modifications to the diagram introduced with GRE-81-21 (see ECE/TRANS/WP.29/GRE/81, Annex II).
31. The expert from IWG SLR recalled the previous discussions on the aiming diagram in paragraph 188.8.131.52.2. (ECE/TRANS/WP.29/GRE/81, para. 10 and Annex II) and presented GRE-82-25, which had been prepared in line with the GRE request. The expert from Poland proposed a revised diagram (GRE-82-43). For the diagram in GRE-82-25, the experts from Japan, Poland and the United Kingdom expressed their preference to maintain the 2000 lm criteria for automatic levelling and headlamp cleaning. The experts from Germany and the United Kingdom pointed out the need to consider the aiming tolerance for the purposes of, respectively, Periodic Technical Inspections (PTI) and Conformity of Production (CoP). GRE requested IWG SLR to consider the above elements and to prepare a revised document for the next session of GRE.
