Documentation Discussion/Report

7. On behalf of the Informal Working Group ‘Simplification of the Lighting and Light-Signalling Regulations’ (IWG SLR), the expert from GTB reported on the progress and schedule of IWG SLR (GRE-77-32). GRE noted that the three new draft Regulations on Light-Signalling Devices (LSD), Road Illumination Devices (RID) and Retro-Reflective Devices (RRD) would be officially submitted to the next session of GRE. The expert of EC urged GRE experts to study these comprehensive documents and to provide their comments and contributions to IWG SLR without delay, so as to have a smooth adoption of the draft Regulations at the next session.

8. GRE took note of a first draft LSD Regulation prepared by IWG SLR (GRE-77-05). GRE commended IWG SLR on the quality of this document and delivered some preliminary remarks on its content. In particular, GRE requested additional explanations on how the amendment process, including new series of amendments and approval markings, would work for the new LSD Regulation which covers many different devices.

9. GTB invited GRE to provide guidance on how to treat the GTB proposals submitted to the previous session of GRE and deferred to the present session for final decision, in the context of drafting the three new Regulations (GRE-77-07). These proposals included the introduction of light emitting diode (LED) substitute light sources in the LSD Regulation (see para. 13 below), introduction of LED light sources in the RID Regulation (para. 15 below) and simplification of the conformity of production (CoP) requirements for adaptive front-lighting systems (AFS) (para. 28 below). GRE agreed to introduce the proposals, if adopted, into the drafts of the new RID and LSD Regulations so that the whole package would be formally submitted to the next session of GRE.

10. The expert from GTB briefly presented his views on Stage 2 of the SLR process and pointed out that it would provide a unique opportunity for China to harmonize their ongoing national simplification process with the SLR requirements.

15. The expert from GTB presented proposals for amendments to Regulation No. 128 and to the Consolidated Resolution (R.E.5) that introduce a new LED light source category for forward lighting applications (ECE/TRANS/WP.29/GRE/2017/5, ECE/TRANS/WP.29/GRE/2017/6, GRE-77-04, GRE-77-12, GRE-77-13). He explained that GTB had abandoned the concept of “thermal grade” and instead proposed the introduction of a maximum test temperature to ensure interchangeability between approved light sources from different manufacturers. GRE also noted the proposal by GTB to incorporate LED light sources into the new RID Regulation (GRE-77-14).

16. The expert from UK requested more time to study the proposals. The expert of Germany proposed modifications to the notion of “maximum test temperature”. GRE decided to revert to this issue at the next session and invited GRE experts to study the proposals and to send their comments to GTB and IWG SLR.

28. GRE reverted to a proposal by the expert from GTB which aligns the conformity of production procedures with the other headlamp Regulations and which simplifies the test methods and requirements relating to conformity of production (ECE/TRANS/WP.29/GRE/2016/28, GRE-77-07). GRE agreed with the proposal and decided to forward it to IWG SLR for inclusion into the new RID Regulation (see paras. 7 and 9 above).

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.
