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.
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 6.2.7.5.1. from 25 to 15 km/h (GRE-82-21). GRE supported this modification.
29. The expert of OICA proposed a new version of paragraph 6.19.7.4. (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.
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.

26. The expert from the Special Interest Group tabled a proposal for a new series of amendments that defines the switching conditions of various lamps and the variable intensity of rear lamps in conjunction with traffic conditions (ECE/TRANS/WP.29/GRE/2021/4 and GRE-84-22).
27. GRE agreed to remove the square brackets in the document and to keep the text inside. GRE adopted the proposal and requested the secretariat to submit it for consideration and vote at the November 2021 sessions of WP.29 and AC.1 as a new 08 series of amendments to UN Regulation No. 48. Following the adoption, the expert from OICA expressed the view that the adopted transitional provisions were too short for the industry.
