7. The Secretary of the Informal Working Group “Simplification of the Lighting and Light-Signalling UN Regulations” (IWG SLR) presented their progress report (GRE-80-30) and proposed revising its Terms of Reference (GRE-80-14). Following an in-depth discussion, GRE agreed that stage 2 of IWG SLR should take over the outcome of the Informal Working Group on Visibility, Glare and Levelling (IWG VGL), and so, adopted the revised Terms of Reference and Rules of Procedure of IWG SLR, as laid down in Annex II. GRE mandated its Chair to seek the consent of WP.29, at its November 2018 session, to extend the mandate of IWG SLR until the end of 2022. At the same time, GRE agreed not to extend the mandate of IWG VGL beyond 2018.
