22. The experts from GTB proposed to correct an editorial error in the markings for light source control gear and to provide clarification in case the tolerance limits are calculated (ECE/TRANS/WP.29/GRE/2025/11, ECE/TRANS/WP.29/GRE/2025/12). GRE adopted the proposals and requested the secretariat to submit them for consideration and adoption to the March 2026 sessions of WP.29 and AC.1 as draft Supplement 6 to the 01 series of amendments to UN Regulation No. 148. GRE also mandated the secretariat to merge these proposals with the ones in GRE-92-14 (see para. 9 above).
