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 .

Presentation on visualisation of signals for help

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 to amends requirements for LED light source modules and non-replaceable light sources. Amendments specify headlamp and AFS technical specifications including light source module characteristics, electrical interfaces, and photometric values. Requirements for LED light source modules and non-replaceable light sources address design, manufacture, testing conditions, colour rendering, UV-radiation, and objective luminous flux measurement procedures.

The GRE-IWG SLR is simplifying UN Lighting and Light-signalling Regulations through a two-stage process. Baseline documents for UN Regulations 48, 53, 74, and 86 have been prepared as carriers of technical amendments. Stage 2 work addresses improved visibility of rear direction indicators against stop lamps, apparent surface definitions, and correction of errors in UN Regulation 150.

Proposal to amend to fit Automated Driving System (ADS) requirements. New provisions introduce vehicles of categories X and Y equipped with an ADS, extending application to vehicles without driver’s compartment and manual driving controls.

Proposal to editorially correct approved proposal GRE/2024/21/Rev.1 and WP.29/2025/112. Editorial corrections amend paragraph 1 to include reversing projectors and direction indicator projectors in scope. New paragraph 3.1.2.10 requires drawings showing relative position of direction indicator projector and lamp. Tables 1 and 2 are amended to add reversing projector and direction indicator projector entries.

IWG EMC prepared supplement 3 to the 07 series of amendments to UN R10, with terminological adjustments for ADS adoption, addition of categories X and Y, technical refinement of ADS including a new ADS table in Annex 6 paragraph 2.1.1.2, and modifications to artificial networks with discharge voltage below 50 V and maximum discharge time of 20 seconds. For the 08 series, approved proposals are prioritised on a roadmap.

The IWG-EMC 51st session (March 2026) addressed the roadmap for UN R10.08 amendments and proposals. Key discussion items included transitional provisions for UN R10.07, artificial network corrections for Supplement 3, harmonics and flicker requirements, radiated emissions aligned with CISPR standards, and extensive work on automated driving system (ADS) fitness requirements. The group extensively debated ADS test configurations, immunity and emissions testing, laboratory capabilities, and steering system requirements. Multiple proposals—including IWG-EMC-51-04, IWG-EMC-51-06, and IWG-EMC-51-07 on harmonics and flicker—were discussed. The session concluded with plans to submit ADS fitness proposals and artificial network corrections as Supplement 3 of UN R10.07 to GRE, with next meetings scheduled for May and July.

Proposal to:

• Update terms of reference for the Informal Working Group on Electromagnetic Compatibility with the objective to review current electromagnetic compatibility requirements and develop within UN R10 a proposal to ensure electromagnetic compatibility,
• Define essential requirements in performance terms,
• Limit measurement workload,
• Update references to standards and vehicle categories,
• Adapt requirements to technical progress,
• Reconsider limits and frequency ranges,
• Include provisions related to automated driving systems,
• Consider software updates,
• The IWG shall operate under consensus with Germany as Chair and OICA as Secretary,
• Circulate documents five working days in advance,
• Distribute minutes within fifteen working days,
• Present an informal document for consideration at GRE’s 97th session in October 2027 and a formal document for the 98th session in April 2028, with final submission by end of January 2028.

OICA opposes inclusion of four roadmap items in UN R10.08 amendments based on WP.29 principles for evidence-based rulemaking. Items 2 and 2bis (radiated emissions below 30 MHz) fail reproducibility standards, lack validated test methods for all vehicle categories, and rely on standards not applicable to internal combustion engine vehicles. Item 3 (16 GHz range) violates the requirement for specific standard versions as CISPR 12 lacks finalized methodology. Item 4 (variable driving conditions and 4-side antenna assessment) presents measurement reproducibility concerns. OICA recommends deferral pending publication of validated international standards.
