Proposal to exempt external status indicator lights (e.g., in mirror lamps for blind spot sensor, status of refrigerated trailer cooling systems, trailer REESS status indicators, tyre pressure indicators, ABS status indicator) from UN R48 while specifying permissible colors and behaviors to avoid confusion with police, emergency, and other priority-vehicle lighting.

This paper has been submitted by the expert from Australia to clarify with the GRE if/where lamps other than those defined/specified in UN Regulation No. 48, including external optical signals to indicate the operating status of a trailer system, can be fitted to vehicles in conformity with this Regulation.
