Proposal to introduce requirements for replaceable light-emitting diode (LED) light sources for forward lighting in the new Regulation on Road Illumination Devices (RID). As the Informal Working Group “Simplification of the Lighting and Light-Signalling Regulations” (IWG SLR) continues working on the new RID Regulation, it is not possible to indicate all detailed modifications that will be required to incorporate the replaceable LED light sources for forward lighting. However, in general, only simple editorial changes will be required. Further work is required to identify the changes that will be required in the annexes.
