11. The expert from GTB proposed to phase out a set of light source categories in Regulation No. 37 (ECE/TRANS/WP.29/GRE/2015/29). GRE agreed that this proposal should be incorporated into the revised draft Resolution on the common specification of light source categories (see paras. 9 and 10 above). GRE also discussed whether phasing out of light source categories could be done only by amending the Resolution or specific transitional provisions should also be introduced into Regulation No. 37. GRE decided to revert to this issue at a later stage.

12. The expert from GTB proposed to introduce new light source categories into Regulation No. 128 and to align some drawings (ECE/TRANS/WP.29/GRE/2015/30). GRE agreed that, bearing in mind its importance for the industry, this proposal should be treated separately from the draft Resolution on light sources. GRE adopted the proposal and requested the secretariat to submit them to WP.29 and the Administrative Committee of the 1958 Agreement (AC.1) for consideration and vote at their March 2016 sessions as draft Supplement 5 to the original series of Regulation No. 128.
