25. The expert from IMMA proposed to introduce sequential activation of light sources of direction indicators (ECE/TRANS/WP.29/GRE/2015/37). GRE adopted this proposal and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their March 2016 sessions as draft Supplement 18 to the original series of amendments to Regulation No. 50.

22. On behalf of the Task Force on Sequential Activation (TF-SA), the expert from Finland reported on its activities and proposed to clarify the requirements for direction indicators with sequential activation in Regulations Nos. 6 and 50 (ECE/TRANS/WP.29/GRE/2016/20 and GRE-76-10). The proposals received written comments from the experts of France, India and OICA (GRE-76-05, GRE-76-09 and GRE-76-16). Following an extensive discussion, GRE adopted the amended proposals, as laid down in Annex IV. At the same time, GRE was not in a position to reach consensus on whether or not the proposals would require a new series of amendments and/or transitional provisions. GRE decided to come back to this issue at the next session in April 2017. Meanwhile, the secretariat was requested to issue the adopted text (Annex IV) as a document for the June 2017 session of WP.29, upon the understanding that any possible amendments, to be decided by GRE in April 2017, could exceptionally be submitted to WP.29 as a corrigendum or addendum to this document.
