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.
