20. The expert from GTB proposed to correct a reference for determining the size of the approval mark (ECE/TRANS/WP.29/GRE/2024/17). GRE adopted the proposal and requested the secretariat to submit it for consideration and vote at the March 2025 sessions of WP.29 and AC.1 as draft Supplement 4 to the 01 series of amendments to UN Regulation No. 148.

21. The expert from GTB tabled proposals which introduced reversing projections. These proposals were submitted in a package with the corresponding amendments to UN Regulation No. 48 (ECE/TRANS/WP.29/GRE/2024/20, GRE-91-05). During an in-depth discussion, experts made numerous comments on the proposals. The expert from the United Kingdom did not see the need for reversing projections in the presence of reversing lamps. Based on the GRE feedback, the expert from GTB issued GRE-91-25 in which he summarized the comments received and previewed revised proposals that would be submitted to the next session. GRE invited all experts to check GRE-91-25 and provide any additional comments to GTB before 15 November 2024, with the aim to prepare a new working document for the next session.

22. The expert from GTB proposed introducing direction indicator projections (DIP). The proposals were accompanied by draft amendments to UN Regulation No. 48 (ECE/TRANS/WP.29/GRE/2024/21, GRE-91-06). A number of GRE experts were not in a position to support the proposals and questioned the safety benefits of DIP, except in particular use cases. Some experts raised concerns about possible light pollution from DIP. The expert from Japan reported that his country had conducted tests of DIP in September 2024 the results of which would be shared with GRE in due course. The Chair concluded that the DIP proposals were not ready for GRE adoption at this time.
