This baseline draft for UN R48 (10 series of amendments) establishes uniform provisions for vehicle lighting and light-signalling device installation. The document reflects all modifications agreed at GRE-94 and incorporates an updated proposal from IEC regarding technological neutrality for LS devices. Key additions include provisions for work lamps to be included after formal WP.29 adoption in June 2026, updated tables for positioning and geometric visibility angles (Annexes 18–19), and revised terminology replacing “dipped-beam/main-beam” with “passing-beam/driving-beam” throughout. Open points address apparent surface visibility against stop lamps and consistency with IWVTA transitional provisions, with transitional provisions for the 10 series specifying acceptance dates and phase-in periods to be finalized.

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 document addresses simplification of the definition of “apparent surface” and single lamp distance requirements in UN R48. It presents a new CAD-based concept defining apparent surface using light emitting surface with clear outer lens disregarded. The document notes that current regulation allows multiple ways to define apparent surface resulting in different distances, with existing approvals having distances significantly larger than 75mm between distinct parts without known safety issues. GTB agrees on simplifying the apparent surface definition to describe function contours as seen by road users, while acknowledging this should not restrict possible designs. The document references a 1999 INF Milano study concluding symmetric appearance is relevant for vehicle identification and larger distances are acceptable for symmetric compared to asymmetric constellations.

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.

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.

Annex 6 specifies methods for measuring variations in motor vehicle passing-beam inclination caused by changes in vehicle attitude due to loading. Para. 4 establishes vehicle preparation requirements: vehicles shall have travelled between 1,000 km and 10,000 km; tyres shall be inflated to full-load pressure with full fuel replenishment; parking brake released and gearbox in neutral; conditioning for at least 8 h at specified temperature; and headlamps with well-defined passing-beam cutoff should preferably be installed. Comments on para. 4 question compatibility with periodic technical inspection (PTI) requirements.

OICA opposes introducing a regulatory requirement for horizontal adjustment of passing-beam/driving-beam and for AFS/ADB to the current SLR agenda. The proposal does not contribute to simplification of lighting regulations, no identified safety concern or ambiguity justifies this requirement, and it lacks a formal proposal from a Contracting Party, NGO, or other stakeholder. The SLR group is managing several longstanding unresolved issues, and introducing this topic risks further delaying progress. Harmonized requirements require comprehensive understanding of Periodic Technical Inspection specifications across all Contracting Parties, which are currently unavailable.

This document presents the draft agenda for the 8th meeting of the GRE Task Force on Glare Prevention, scheduled for 9 June 2026 at CLEPA Headquarters in Brussels. The agenda includes welcome remarks, adoption of the agenda, approval of the previous meeting report, feedback from GRE-94, and status updates on HWT on PTI, ADB/AFS, and Regulation 48. Discussion topics cover horizontal adjustment of passing- and driving-beam and AFS-ADB, vehicle preparation for passing-beam measurement, and updates from the GTB Task Force Glare Control. Future meetings are scheduled for Tokyo in September 2026 and Brussels in December 2026.

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.

Baseline document for stage 2 of UN Regulation No. 48, based on R48-09 (R48-08 up to Supplement 04 and WP.29/2024/28, WP.29/2025/36, with modifications agreed at GRE-92 and GRE-93

Proposal for editorial work with thorough review and consistency improvements. New informative Annexes for lamp positioning and geometric visibility angles are added. Technical prescriptions now pertain only to the new series. Light source provisions are clarified regarding technological neutrality, usage of light source modules, and non-replaceable light sources.

Proposal to add VRU warning pattern requirements. Document presents data from accident databases showing pedestrian crossing conflicts represent the highest proportion of nighttime road accidents at approximately 32% with obstructions and 19% without. Limited visibility and restricted communication between drivers and VRUs necessitates an assistance function. A spotlight feature with a bright narrow beam pattern directed at hazardous VRUs, moving with the target and flashing to remind drivers while warning VRUs, received positive feedback from customer experience surveys

Proposal clarifies the “Manufacturer logo” means a light emitting graphic mark, emblem, word, or combination of those elements used to aid public identification of a vehicle manufacturer’s brand name when the function is switched ON. Improved justification for the proposal

Paper introduces an ADS marker lamp to identify vehicles operating with an Automated Driving System. Industry does not seek to mandate such a lamp. It identifies safety and security concerns including no demonstrated real-world net safety benefit, targeting and public violence risks, cargo robbery risks, child safeguarding concerns, cyber-physical attack surface expansion, and spoofing and misuse potential.

Proposal provides an alternative proposal to GRE/2024/12 Revision 2 as amended by GRE-93-28 Revision 1 .

Proposal to add editorial corrections to UN R48 series 06 to 09 based on GRE/2024/21/Rev.1 and WP.29/2025/114. Changes include inserting definitions for direction indicator projector, basic element, and direction indicator projection; adding requirements for direction indicator projections

Proposal for a supplement to the 06/07/08/09 series of amendments to UN Regulation No. 48 and the 02 series of amendments to UN Regulation No. 148 concerning manufacturer logos in side-marker lamps. The proposal amends paragraph 5.5.5. of UN R48 to clarify that no restrictions apply to logos in side-marker lamps, and amends paragraph 4.5.5. of UN R148 to add side-marker lamps to the list of lamps that shall not incorporate a logo. The justification references ECE/TRANS/WP.29/GRE/2020/5/Rev.2.
