Proposal to clarify the markings. Some countries and regions refer to the requirements of the 00 series of amendments to UN R149, or to older regulations. In order to avoid the redundant burden to mark the symbols of both the 00 and 01 series on the lamp (e.g., “HCR” or “HR and C”), the proposal would allow for consistency of the symbols between the 00 and the 01 series of amendments. UN R149 also includes passing-beam requirements designed to provide symmetrical “cut-off” line: the proposal introduces examples in Annex 13.
24. The expert of GTB proposed to clarify the markings and measuring of the quality of the “cut-off” (ECE/TRANS/WP.29/GRE/2024/7 and ECE/TRANS/WP.29/GRE/2024/8). GRE adopted the proposal and requested the secretariat to submit it for consideration and vote at the November 2024 sessions of WP.29 and AC.1 as draft Supplement 4 to the 01 series of amendments to UN Regulation No. 149 (also see the next paragraph).
25. The expert from China pointed out possible inconsistencies in various tables for the conformity of production (GRE-90-29). GRE requested GTB to study the issue and prepare corrections for consideration at the next session. For Table 22 (GRE-90-29, page 2), GRE agreed to include, without delay, the proposed correction in draft Supplement 4 to the 01 series of amendments to UN Regulation No. 149 (see the previous paragraph).
