45. The GRE Chair reported on the results of the seventy-eighth session of GRE (ECE/TRANS/WP.29/GRE/78).

46. The GRE chair briefed WP.29 on the progress in preparing a new UN Regulation on Light-Signalling Devices (LSD) and on a new approach of streamlining the traditional approval markings in the new LSD Regulation which covers many devices and where the most stringent requirements for various devices may correspond to different series of amendments. Given the fact that DETA and the Unique Identifier (UI) might not be available upon the entry into force of the new UN Regulations, the new UN Regulations will include a fall-back solution for approval markings, in addition to the UI, until the availability of the UI. He also mentioned that GRE had adopted amendments to UN Regulation No. 128 (LED light sources) and to the Consolidated Resolution on the common specification of light source categories (R.E.5) with the aim to introduce LED light sources for forward lighting applications.

47. WP.29 gave its consent for extending the mandate of the Informal Working Group on Visibility, Glare and Levelling (IWG VGL) until the end of 2018 and noted that GRE had re-elected Mr. M. Loccufier (Belgium) as Chair and Mr. D. Rovers (Netherlands) as Vice-Chair for the year 2018.
