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.
