GRE held its ninety-fourth session from 27 to 30 April 2026 in Geneva. The Working Party adopted proposals for amendments to UN Regulations on lighting and light-signalling devices, including proposals to UN Regulation No. 148 and No. 149 as draft Supplement 8 to the 01 series, and to UN Regulation No. 10 as draft Supplement 3 to the 07 series, mandating the secretariat to submit these to the June 2026 and November 2026 sessions of WP.29 and AC.1 as appropriate. GRE agreed to continue consideration of several proposals at its next session, including those on call for help signals, manufacturer logos in lighting devices, pair of lamps clarification, retro-reflective device colour requirements, selective yellow for front lamps, supplemental light-signalling devices, and direction indicator projections, noting concerns from vulnerable road users representatives. GRE extended the mandate of the Informal Working Group on Electromagnetic Compatibility until December 2028 and decided to continue technical discussions on automated driving system marker lamps. The next session is scheduled for 20 to 23 October 2026, with a working document submission deadline of 27 July 2026.
