32. GRE was informed that WP.29, at its November 2016 session, had requested GRE, in cooperation with IWG on IWVTA, to clarify the individual Regulations on lighting and light-signalling devices with a requirement that light sources in these devices should be type approved pursuant to Regulations Nos. 37, 99 or 128 (ECE/TRANS/WP.29/1126, para. 62). In line with this request, the expert from EC proposed collective amendments to device Regulations and to Regulation No. 48 (ECE/TRANS/WP.29/GRE/2017/7, Informal document GRE-77-30-Rev.1). Following an in-depth discussion, GRE adopted the proposals for amendments, as laid down in Annex IV, and requested the secretariat to submit them to WP.29 and AC.1 for consideration and vote at their June 2017 sessions.
