42. [The GRE chair] informed WP.29 about the deliberations of GRE and its newly established IWG “Simplification of the Lighting and Light-Signalling Regulations” (IWG SLR) to streamline UN Regulations under GRE’s responsibility. GRE adopted the ToR and Rules of Procedure for SLR, which would be submitted to WP.29 for approval. WP.29 gave its consent to establish the IWG. For the purposes of simplification and in line with the ideas of SLR, the expert from IEC proposed to separate data sheets for various light sources from Annex 1 to UN Regulations Nos. 37, 99 and 128 and to place them in a repository document administered by WP.29 (WP.29-164-18). WP.29 endorsed the proposed approach.

20. The Chair introduced GRE-72-20 proposing the terms of reference and rules of procedure of the Informal Working Group “Simplification of the Lighting and Light-Signalling Regulations” (IWG SLR). Having introduced minor editorial corrections, GRE adopted the proposal as reproduced in Annex VIII to this report. GRE also agreed that IWG SLR superseded the Horizontal Reference Document Informal Group which ceased to exist.
