Status report on the Task Force on Lamp Under Parked Conditions (TF-LUPC). The group held two meetings since the 94th GRE session and continued developing a proposal on energy status indicators and lamp test modes. Open issues require advice from GRE experts on the number and switching conditions of energy status indicators, their size and colour, and on lamp test mode categories, AFS modes and classes, test duration, and inclusion of warning lamps. The group plans to submit a final proposal to the 96th GRE session in April 2027 for integration into the 10 Series of amendments to UN R48.
