UN R53 series ⁰⁵ baseline amendments simplify the definition in paragraph 2 by deleting common definitions to UN R48, reducing from 49 original definitions to 27. Amendments align failure provision and EV inclusion with UN R48. The communication sheet is amended to align with UN R48. Terminology and format alignment with UN R48 and UN R74 is applied. Previous technical prescriptions are moved to a reference document, keeping only the latest. Paragraphs 6.×.4 and 6.×.5 are simplified, aligning with UN R48. An open point questions whether Annex 1 Communication form should refer to a specific Series of Amendments to R48 definitions.

This amendment modifies definitions in paragraph 2, consolidates general specifications in paragraphs 5 and 6, simplifies failure provisions, includes electric vehicles, aligns terminology with UN R48 baseline and standardizes vehicle category references to “vehicles of category(ies),” corrects AFS provision references, applies scientific notation with lumens, aligns approval number text with UN R48, corrects signal lamp category numbering, uses category symbols instead

Proposal to amend UN R74 series 04 by simplifying the definition in paragraph 2 through deletion of common definitions to UN R48, applying amendments for failure provision and EV inclusion, aligning terminology and format with UN R48 and UN R53, retaining only the latest transitional provisions, simplifying paragraphs 6.×.4 and 6.×.5, and providing editable pictures.

Proposal to amend the definitions ; add EV inclusion; clarify individual and general provisions, failure provisions, and transitional provisions; correct signal lamp category; use category symbol instead of lamp function name;

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.

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.

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 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 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 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.

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.

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.

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.

Proposal to replace “multiple separate light sources” with “multiple light sources” in the provision governing rear position lamps reciprocally incorporated with stop lamps.

Proposal to introduce Automated Driving System (ADS) requirements into the Regulation and correct figures in Appendix 8. The proposal inserts new introductory paragraphs addressing vehicles of categories X and Y equipped with an ADS; amends paragraph 1.3 to include ADS control requirements; inserts new paragraph 2.9.4 on ADS presence; extensively revises paragraph 2.12 on immunity related functions to include ADS-related functions; deletes paragraphs 2.26 and 2.27; inserts new paragraph 2.32 defining “ADS test configuration”

GRE held its ninety-fourth session from 27 to 30 April 2026 in Geneva. The Working Party adopted proposals for amendments to UN Regulations on lighting and light-signalling devices, including proposals to UN Regulation No. 148 and No. 149 as draft Supplement 8 to the 01 series, and to UN Regulation No. 10 as draft Supplement 3 to the 07 series, mandating the secretariat to submit these to the June 2026 and November 2026 sessions of WP.29 and AC.1 as appropriate. GRE agreed to continue consideration of several proposals at its next session, including those on call for help signals, manufacturer logos in lighting devices, pair of lamps clarification, retro-reflective device colour requirements, selective yellow for front lamps, supplemental light-signalling devices, and direction indicator projections, noting concerns from vulnerable road users representatives. GRE extended the mandate of the Informal Working Group on Electromagnetic Compatibility until December 2028 and decided to continue technical discussions on automated driving system marker lamps. The next session is scheduled for 20 to 23 October 2026, with a working document submission deadline of 27 July 2026.
