Task Force on Lamps Under Parked Conditions held its 11th session on 8–10 June 2026 in Paris. The agenda and previous report were adopted without changes. Experts reviewed proposals for modifications to UN R48, discussing energy status indicator colour conventions, apparent surface requirements, numbers of indicators for multiple charging connectors, and lamp test modes. Key decisions included restricting indicator illumination to connectors in use, maintaining 1–25 cm² apparent surface for most indicators with 1–150 cm² for connector-surrounding indicators, and performing one mode test per class in neutral state. The next meeting is scheduled for 11 September 2026 in Tokyo, with a final proposal targeted for April 2027 GRE session.

Based on SLR-73-07/Rev.1 including LUPC-01-03, this consolidated and amended text of UN R48 defines uniform provisions for vehicle lighting and light-signalling device installation. The regulation establishes requirements for vehicles of categories M₁–M₃, N₁–N₃, and O₁–O₄ regarding lamp presence, positioning, geometric visibility, orientation, electrical connections, and tell-tales. Key additions include energy status indicators providing charge status information via white, amber, red, selective-yellow, indicator blue, or indicator green light; lamp test mode enabling user-performed visual function checks of lighting systems; and enhanced driver assistance projections. Transitional provisions establish type-approval acceptance deadlines with mandatory application dates from September 2027 for M and N₁–O₂ vehicles and September 2028 for N₂–O₄ vehicles.

The agenda includes review of Terms of Reference and Rules of Procedure, a recap of the GRE 94th session, discussion of questionnaires, a proposal for modification of UN R48, follow-up on action items, review of existing Regulations and Standards, and announcement of the next meeting.
