26. The expert from the Special Interest Group tabled a proposal for a new series of amendments that defines the switching conditions of various lamps and the variable intensity of rear lamps in conjunction with traffic conditions (ECE/TRANS/WP.29/GRE/2021/4 and GRE-84-22).

27. GRE agreed to remove the square brackets in the document and to keep the text inside. GRE adopted the proposal and requested the secretariat to submit it for consideration and vote at the November 2021 sessions of WP.29 and AC.1 as a new 08 series of amendments to UN Regulation No. 48. Following the adoption, the expert from OICA expressed the view that the adopted transitional provisions were too short for the industry.

28. The expert from Japan presented a draft new series of amendments that introduces park conditions and an answer-back signal in the scope of UN Regulation No. 48 (ECE/TRANS/WP.29/GRE/2021/2, GRE-84-29 and GRE-84-30). The expert from OICA posed questions on the proposal (GRE-84-33) and the experts from Japan provided their replies (GRE-84-34). Several experts made further remarks on the functionalities of answer-back signals and the proposed selection of lamps for such signals.

29. The Chair concluded that the proposal would need fine-tuning. To make progress and prepare a revised proposal for the next session, GRE agreed to establish a Special Interest Group (SIG) on these topics, which would be co-chaired by the experts from Finland and the Netherlands while OICA would act as Secretary. GRE noted that the first meeting of SIG was planned to take place on 7 June 2021.
