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 Task Force on Vehicular Communications held its thirteenth session on 23rd January 2026 in Geneva. Presentations on Vulnerable Road Users protection were delivered by Japan, China, and Car2Car, addressing VRU accident analysis, pilot projects, national standardization frameworks, and collective perception approaches. Common themes included sensor limitations, functional safety needs, and harmonized communication standards. The Task Force agreed to continue discussions at its next session.
SAE J3224 supports vehicle-based V2X sensor sharing via SDSM. SAE J3224/1 describes infrastructure-based detection and sharing of VRU information, with final approval in Motor Vehicle Council balloting and publication planned for August 2026. SAE J3251 specifies OBU device requirements for CDA-equipped vehicles and wheeled VRU types, with publication targeted for Q3 2027. SAE J5001 on PSM communications is on hold due to spectrum limitations and market adoption issues.
The agenda includes discussions on protecting vulnerable road users.
The agenda includes coordination of work referencing GRPE-92-14, GRPE-93-22/Rev.1, GRSP-78-17, and GRPE-94-06, electrical safety review, cyber security, braking, EMC, power determination and battery range, and draft text for the proposed UN Regulation. Additional meetings are scheduled for 2nd July (Hybrid, Brussels) and 9th September (Online).
