Document Title	LSD: Proposal to introduce requirements for the use of LED substitute light sources
Reference Number	GRE/2018/42
Date	13 Aug 2018
Summary	Proposal to introduce the following changes into the draft new Regulation on light-signalling devices: Use of LED substitute light source(s) is allowed and does not constitute a change of the lamp type. However, lamp performances shall be tested during type approval also with the LED substitute light source. Approval of the lamp using filament light source(s) is a prerequisite for approval of the lamp using LED substitute light source(s). Testing with LED substitute light sources is exempted from conformity of production control. The technical description shall include notice that the lamp also has to be approved with the LED substitute light source(s) according to UN R128 if the applicant has so determined. The approval marking or the Unique Identifier as well as the category or categories of LED substitute light source(s) prescribed, if any, shall be visible. The indication of both the holder of the filament light source and of its LED counterpart light source, if any, shall be explicitly provided.

Excerpts from session reports related to this document
GRE \| Session 80 \| 23-26 Oct 2018			20. GRE also considered a parallel proposal by TF SR which introduced requirements for the use of LED substitute light sources in the new LSD UN Regulation (ECE/TRANS/WP.29/GRE/2018/42). GRE adopted the proposal, as amended by Annex III, and requested the secretariat to submit them to WP.29 and AC.1 for consideration at their June 2019 sessions. 21. The expert of SAE delivered a presentation on standardization of technical requirements for forward lighting LED replacement light sources (GRE-80-34) and offered to organize a live demonstration at the next session of GRE. The expert from FIA highlighted the advantages of using LED retrofits for front lighting application of vehicles in use and argued in favour of developing regulations in this area (GRE-80-33). He suggested that TF SR should prepare proposals. In this regard, some GRE experts expressed doubts whether this issue could be solved by UN Regulations and felt that it should be treated within national law. Those experts were also of the view that TF SR should finalize LED substitutes for front-lighting applications and then stop its activities without addressing LED retrofits. GRE decided to revert to this discussion at the next session and requested TF SR to continue its work in the interim.
