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.

The session discussions addressed the Energy Status Indicator, including modifications to paragraph 2.5.22. defining illumination to assist socket connection, revisions to paragraph 6.29.9. establishing maximum flashing frequency of 5 Hz, and paragraph 6.29.9.5. setting surface size limits up to 150 cm² around sockets. Colour convention for charging status indicators was debated, with proposals for blue (charging), green (charged), orange (failure), and red (danger), to be discussed at the April GRE session. The Lamp Test Mode section addressed concerns regarding testing scope and removed requirements for AFS testing and driving beam testing.

OICA proposes amendments to LUPC-09-04: amend para. 2.5.22. to expand the definition of energy status indicator to include information on the operational status of energy transfer and illumination to assist in locating electrical connection; delete existing para. 3.2.10. and its subparagraphs; add new paras. 3.2.10. and 3.2.11. requiring statements on energy status indicator lamps and lamp test mode; and amend para. 6.29.9. to clarify that multiple energy status indicators may be installed, change the flashing frequency limit from 2.0 Hz to 5.0 Hz, and enlarge the maximum apparent surface area to accommodate various plug sizes and surrounding illumination designs.

The Task Force on Lamps Under Parked Conditions examined proposed modifications to UN R48 regarding vehicle lamp test modes, focusing on energy status indicators for charging vehicles. Key discussions included: color specifications for indicators, multiple energy status indicator placement on vehicles, frequency requirements for flashing indicators, and apparent surface area values. The group debated whether to include Adaptive Front-lighting System modes in lamp test procedures. Multiple paragraphs were revised, deleted, or approved for further consideration at the next session scheduled for March 2026.
