The expert from IMMA recalled the draft 03 series of amendments to UN Regulation No. 53 adopted at the previous session of GRE (ECE/TRANS/WP.29/GRE/2018/50 and ECE/TRANS/WP.29/GRE/80, para. 28) and proposed to restore the original automatic headlamp requirement for vehicles not equipped with daytime running lamps (DRL) (ECE/TRANS/WP.29/GRE/2019/12). GRE adopted the proposal and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2019 sessions as part of the draft 03 series of amendments to UN Regulation No. 53. The expert from EC was not in a position to support the proposal.

7. (b) | UN Regulation No. 53 (Installation of lighting and light-signalling devices for L3 vehicles)

28. On behalf of the Special Interest Group for DRL of L-category vehicles, the expert from Japan presented a revised proposal that introduced a new requirement for automatic switching from DRL to the headlamp for L3 category in UN Regulation No. 53 as well as a corresponding amendment to the new LSD UN Regulation (ECE/TRANS/WP.29/GRE/2018/50). The expert from India proposed to delete references to “passing beam” (GRE-80-25). The experts of Germany, Netherlands, UK and EC were not in favour of deleting “passing beam” and supported the original proposal. GRE adopted the proposal and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their June 2019 sessions as draft 03 series of amendments to UN Regulation No. 53 and draft Supplement 1 to the original LSD UN Regulation, subject to the following amendments:

Paragraphs 5.11.1.1., 5.11.1.2. and Annex 7 (twice), replace “headlamp [(passing beam)]” with “passing beam”.

Paragraphs 11.8. and 11.10., remove square brackets around 2023.
