25 Apr GRSP Informal Working Group on Children Left In Vehicles () GRE-94-15/Rev.1 2026-04-25 This paper is to inform relevant GRs of the ongoing activities within the CLIV informal group and the potential influence on the work under the responsibilities of the GRs. CLIV is in Phase 2 developing a new UN Regulation on Children Left in Vehicles for vehicle categories M<sub>1</sub>, M<sub>2</sub>, M<sub>3</sub> and N<sub>1</sub>. The draft regulation includes requirements for visual and audible external warnings upon detecting a CLIV event. The IWG prioritises development for buses first, then light vehicles. The draft regulation aims to mitigate risk of serious or fatal injuries to children left in vehicles. Upon detecting a CLIV event, visual and audible external warnings will be generated using an SOS morse code pattern to distinguish from existing warnings.
24 Apr UN R86: Highlights of the baseline amendments to 04 series of amendments GRE-94-39 2026-04-24 UN R86 baseline amendments add agricultural non-road mobile machinery to scope. Definitions are simplified by removing common vehicle definitions and aligning structure with UN R48. Headlamps symmetrical classes are reviewed following CLEPA comment. Side retro-reflector requirements align with EU requirements on location. Direction-indicator lamps alignment with EU scope for tractors remains an open point.
24 Apr UN R48: Revision 6 of 04 series of amendments GRE-94-40 2026-04-24 Proposal applies to vehicles of categories T, R, and S and agricultural NRMM regarding lighting and light-signalling device installation. The regulation establishes approval procedures, general specifications for lamp fitting and adjustment, electrical connections, and individual specifications for various lighting functions including driving-beam and passing-beam headlamps, direction-indicator lamps, stop lamps, position lamps, retro-reflectors, and other light-signalling devices. It specifies position requirements (height, width, length), geometric visibility angles, colour requirements, and electrical interconnection rules. Transitional provisions address implementation across different amendment series, with staggered acceptance periods for type-approvals granted under preceding series of amendments.
24 Apr UN R48: Highlights of the baseline amendments for 10 series of amendments GRE-94-41 2026-04-24 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.
24 Apr UN R48: Proposal for a Supplement to the 08 to 09 Series of amendments (China) GRE-94-42 2026-04-24 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 China
24 Apr UN R48: Proposal for a Supplement to the 08 to 09 Series of amendments (OICA) GRE-94-43/Rev.2 2026-04-24 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 OICA
24 Apr UN R48: Position paper on ADS marker lamps / external identification of ADS Status with using lighting functions - Safety, security and implementation concerns (OICA) GRE-94-44 2026-04-24 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. OICA
24 Apr UN R48: Proposal for a new series of amendments (OICA) GRE-94-45 2026-04-24 Proposal provides an alternative proposal to GRE/2024/12 Revision 2 as amended by GRE-93-28 Revision 1 . OICA
24 Apr UN R10: Proposal for Supplement 3 to the 07 Series of amendments GRE-94-46 2026-04-24 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.

24 Apr UN R48: Proposal for a Supplement to the 06, 07, 08 and 09 series of amendments (Czech Republic) GRE-94-48 2026-04-24 Presentation on visualisation of signals for help Czech Republic
24 Apr UN R48: Proposal for editorial corrections GRE/2024/21/Rev.1 (GTB) GRE-94-49 2026-04-24 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 GTB
24 Apr UN R148: Proposal for corrections of text (GTB) GRE-94-50 2026-04-24 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. GTB
24 Apr Survey Outcome among VRUs on Direction Indicator Projection (GTB) GRE-94-51 2026-04-24 Survey of Vulnerable Road Users associations on Direction Indicator Projection, Independent third-party research from six countries confirms safety benefits and lack of confusion and analysis shows most VRU collisions occur in urban areas near junctions during vehicle turning.

28 Apr UN R10 : IWG EMC Status report GRE-94-53 2026-04-28 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.
28 Apr Energy Saving Opportunities in Automotive Lighting: GTB Activities Status Report (GTB) GRE-94-54 2026-04-28 A 2025 study by TU Darmstadt concluded that a daylight running light passing-beam switching threshold of 500lx is preferable at sunset, and that adaptive DRL values lower than 400cd seem sufficient. The GTB is developing amendment proposals for DRL/low beam switching thresholds, adaptive DRL, and Class V ECO mode. Annual energy saving potentials range from 55 GWh to 141 GWh across evaluated use cases, with highest savings from DRL intensity adaptation and reduced low beam in city nighttime driving. GTB
