28. The expert from the Special Interest Group (SIG) introduced a new draft series of amendments that defines the switching conditions of dipped-beam and Daytime Running Lamps (DRL) and the variable intensity of rear lamps in conjunction with traffic conditions (ECE/TRANS/WP.29/GRE/2019/20 and GRE-82-07). The experts from Japan and EC proposed to reduce the speed threshold in paragraph from 25 to 15 km/h (GRE-82-21). GRE supported this modification.

29. The expert of OICA proposed a new version of paragraph (GRE-82-35-Rev.1) on switching of the rear position lamps together with DRLs. Some experts were of the view that the rear position lamps “shall be on” (i.e. always on) when DRLs are on, while others expressed preference to “may be on”, for the sake of reducing the energy consumption. Having extensively discussed this issue, GRE agreed that the rear position lamps “shall” be on in case of adverse weather conditions, however, the list of such conditions would need to be improved. GRE also noted that the transitional provisions in ECE/TRANS/WP.29/GRE/2019/20 had to be clarified. GRE invited SIG to consider the comments received and to submit a revised document to the next session.
