At its October 2018 session, the Working Party on Lighting and Light-Signalling considered proposal concerning safeguards against the possible misuse of LED substitutes as retrofits in lamps and/or vehicles that were not type approved for using such light sources. GRE noted that the discussion addressed two different, but interrelated issues: (a) allowing LED substitutes for new type approvals, as part of Original Equipment Manufacturer (OEM) and Original Equipment Supplier (OES), and (b) using LED as retrofits on old vehicle types. Some experts were of the view that the two cannot be separated from one another. Given the complexity of the issues, GRE mandated this task force to develop proposals addressing the misuse concerns.
