Proposal to insert a new definition of functional test configuration, amend para. 2.1.1.2. to clarify that test conditions are agreed between manufacturer and technical service and that tables provide guidance which may be extended or amended depending on vehicle characteristics, add tables specifying basic vehicle test conditions for “50 km/h mode,” “Brake mode,” and “Active ADS Mode,” add an alternative “Brake mode” with active ADS for vehicles where braking mode cannot be applied with ADS operational without ADS feature(s) activated, add AECS and AVAS test condition tables, and insert a new table cross-referencing UN Regulations with specific provisions and test configurations to demonstrate compliance with UN R10.

Document raises question on the use of a combination of Level I/II immunity tests based on ISO 7637-2:2011 in the 07 series given that the 06 series prescribed Level III.

International reference standards for harmonics and flicker testing define differing applicable supply voltage levels and operating frequencies. CLEPA proposes maintaining baseline requirements for UN R10.08 unchanged, testing according to standardized parameters of reference IEC standards. Contracting Parties with diverging local grid configurations should define tailored national requirements or propose harmonized evaluation methods directly within relevant IEC standard committees, as direct application or mathematical conversion of limits for diverging grids lacks standardized metrological foundation in IEC publications.

The session reviewed and adopted the draft agenda and prior meeting minutes. Substantive discussions addressed proposals including harmonics observation time for vehicles and energy storage assemblies (EMC-54-02), conducting automated driving system active tests (EMC-54-03), quality guidance for technical service test reports (EMC-54-04), amending UN R10 based on related regulations (EMC-54-05-Rev.1), minimum dwell time guidance (EMC-54-06), non-durable protection shields clarification (EMC-54-07), and transient immunity (EMC-54-10-Rev.1). The group concluded that further investigation and revised proposals are needed for several items by the December 2026 session. Next meeting: 2–3 December 2026 online.

Proposal to amend UN R74:

• Simplify definitions by referring to UN Regulation No. 48,
• Replace vehicle type references with vehicles of category L₁,
• Use hyphens in “type-approved” and “direction-indicator lamp”,
• Add provisions for electric vehicle inclusion,
• Consolidate general and individual lamp specifications,
• Reorganize geometric visibility requirements into paragraphs 5.5 and 5.6,
• Add para. 5.22 regarding lamp operation requirements,
• Create summary tables in Annexes 6 and 7 for lamp positioning and geometric visibility angles,
• Revise approval marks in Annex 2,
• Reserve Annex 3,
• Establish transitional provisions for the 04 series with dates to be determined (1 September [20xx]).

Simplification work on UN Regulation No. 86 addresses five pending points: the number of additional direction-indicator lamps allowed, geometric visibility of category 6 direction-indicator lamps, height for slow-moving vehicles marking plates set as low as possible above the ground but not less than 250 mm at the lower edge, position for slow-moving vehicles marking plates with regard to the vehicle median longitudinal plane, and speed for automatic activation of manoeuvring lamps proposed at 15 km/h as a compromise.

SLR will deliver Stage 2/Step 2 to GRE-96 by end of January 2027 for submission to WP.29 in November 2027. SLR’s mandate ends December 2027. A new informal working group on Supporting technical experts on Lighting Regulation (SteLR) will be established, chaired by EC and vice-chaired by Germany, to address remaining open points from SLR and TF-GP. Main topics include visibility of signalling functions, glare prevention, apparent surface, energy saving, replaceability and sustainability, and V2X communication.

This document is a baseline for UN Regulation 48 (Stage 2/Step 2) concerning vehicle lighting and light-signalling devices. It incorporates all amendments from multiple series and includes provisions for adaptive front-lighting systems (AFS), driver assistance projections, reversing projections, direction-indicator projections, and automated driving system (ADS) features. The regulation establishes requirements for the design, installation, and operation of lighting devices on vehicles of categories M, N, and O, with comprehensive specifications for individual lamp types, geometric visibility angles, electrical connections, and tell-tale requirements. It includes transitional provisions allowing approvals under preceding series while establishing phased implementation timelines for new requirements.

The agenda includes adoption of previous session reports, correction of errors in Regulation 150-01, improvement of direction indicator visibility, rearrangement of lamp provisions in Regulation 48, consistency checks for geometric visibility angles, baseline documents for Regulations 48, 53, 74, and 86, review of transitional provisions, discussion of apparent surface definitions, and submission preparation for GRE-95.

Based on AVSR-31-03/Rev.2 and GTBWGSL 7201, this work-in-progress draft proposes a new UN Regulation for ADS Marker Lamps. The proposal applies to vehicles of categories M, N, L₆, L₇, and O. It establishes approval procedures for ADS Marker Lamp components and vehicle installation requirements if fitted on a vehicle (the draft includes a tentative statement that nothing prevents prohibiting the use of ADS marker lamps). Key provisions include luminous intensity requirements with day-time and night-time levels for front (AMF), rear (AMR), and side (AMS) lamps; blue-green colour specifications; approval marking and labelling requirements; geometric visibility angles; electrical connections ensuring automatic activation when automated driving systems perform the dynamic driving task; and conformity of production procedures. Outstanding discussion items requiring guidance include vehicle category applicability, day-time and night-time condition definitions, reciprocal incorporation with direction indicators, alternative roof-mounted lamp options, and specification details for side marker lamp categories. Testing procedures for light sources and automatic switching conditions between day-time and night-time modes are included in annexes.

Draft agenda for the 34th meeting of the GRE Taskforce on Autonomous Vehicle Signalling Requirements, to be held via WebEx on 22 September 2026. The meeting will discussion of ADS marker lamps including a draft proposal hybrid regulation after an editorial meeting, miscellaneous items, and next steps including a working plan for future activities.

Terms of reference and rules of procedure for the Task Force on Lamps Under Parked Conditions (TF-LUPC). TF-LUPC shall review the requirements of the current suite of lamps under parked conditions and develop proposals within the framework of UN R48 pertaining to Energy Indicator and Lamp test mode. The task force is open to all GRE participants. Two Co-Chairs (Japan/Netherlands) and a Secretary (OICA) shall manage it. Decisions shall be reached by consensus. STEP 2 aims to present an informal document at GRE’s ninety-fifth session in October 2026 and a formal document at the ninety-sixth session in April 2027 for submission to WP.29 as part of the 10 series of amendments.

Draft amendments concerning lamps under parked conditions presented in a consolidated revision of UN R48.

Proposal to introduce a Front Zero-Speed Indicator (FZSI) system on motor vehicles to signal complete vehicle stops to vulnerable road users. The system activates exclusively when vehicle speed equals 0 km/h and deactivates when speed exceeds 0 km/h. A horizontal light strip of minimum 30 cm width positioned at the upper windshield edge or front roofline provides the signal. Primary color is red (wavelength 620–750 nm); secondary option is high-luminance turquoise or green if required by applicable legislation. Brightness adjusts automatically via ambient light sensors. The system integrates with existing vehicle CAN-bus networks and serves as direct communication for autonomous vehicles.

The Czech Republic requests guidance from GRSG on whether automatic activation of a dedicated “Call for Help” signal with higher flashing frequency, instead of the standard hazard warning signal following severe vehicle impact linked to UN Regulation No. 144 trigger criteria, conflicts with existing post-crash safety requirements under GRSG competence. A formal proposal to introduce this new signal within UN Regulation No. 48 has been submitted to GRE under document ECE/TRANS/WP.29/GRE/2026/2.

Progress report of the Task Force on Glare Prevention to the 95th session of GRE in October 2026. The Task Force comprises 11 Contracting Parties and 40+ participants from 11 NGOs. Nine meetings have been held since the kick-off meeting in January 2025. Homework teams have been established on literature examination, Periodical Technical Inspections, and UN Regulation No. 48. Contributions from NGOs address identifying issues with headlamp aiming, classification of glare and rating, and regulatory gaps between UNECE and PTI. Draft recommendations on the first step addressing reflected image distance are presented for GRE decision.

Proposal to amend para. 6.7.4.1. to require minimum distance of not less than 400 mm between inner edges of two apparent surfaces for M₁ and N₁ category vehicles and not less than 600 mm for all other categories, amend para. 6.9.4.1. to require no special requirement for M₁ and N₁ category vehicles and not less than 600 mm for all other categories, and amend para. 6.10.4.1. to require not less than 400 mm for M₁ and N₁ category vehicles and not less than 600 mm for all other categories, addressing concerns about continuous LED light bars affecting hazard perception and traffic safety.
