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.

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 M₁, M₂, M₃ and N₁. 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.

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:

• Amend Table 18 to delete maximum values at point 50L and correct minimum values at point 50L to 1,360 cd (20% CoP) and 1,190 cd (30% CoP) and delete the associated note,
• amend Table 21 to delete maximum values at point 50L and correct minimum values at point 50L to 1,360 cd (20% CoP) and 1,190 cd (30% CoP) and delete the associated note,
• amend Table 23 to correct maximum values at Segment 10 to 7,100 cd (0% CoP), 8,520 cd (20% CoP), and 9,230 cd (30% CoP),
• amend Tables 30 and 31 to correct minimum values at point HV to 25,920 cd (20% CoP) and 22,680 cd (30% CoP),
• amend Table 24 to delete the associated note regarding multiplication by 1.4,
• amend Table 28 to correct point BR maximum values to 2.65×10³ cd (0% CoP), 3.18×10³ cd (20% CoP), and 3.45×10³ cd (30% CoP),
• amend Table 29 to correct point BR maximum values to 2.65×10³ cd (0% CoP), 3.18×10³ cd (20% CoP), and 3.45×10³ cd (30% CoP),
• amend Table 35 to correct CoP minimum values at point 2U-V to 1.04×10⁴ cd (20% CoP) and 9.10×10² cd (30% CoP) and at points H-9L and H-9R to 2.16×10³ cd (20% CoP) and 1.89×10³ cd (30% CoP),
• amend Annex 4, para. 1.6.2.1. to correct references to table notes from notes 1 and 7 to notes a and f of Table 7.

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”

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 amend para. 6.27.9.1. to permit the direction indicator lamp to be operated with the luminous intensity of its original specification when used as an answer-back signal, notwithstanding the 700 cd limitation on or above the HH line that applies to other approved lighting and light-signalling devices and exterior courtesy lamps. The proposal removes restrictions on direction indicator lamps used for answer-back activation of already type-approved light-signalling functions, while maintaining prohibitions on front fog lamps, rear fog lamps, and stop lamps.

Proposal to introduce new LED replacement light source categories H9, H10, HB3 and HIR2. The specifications are derived from enforced LEDr category sheets and adapted to the specifications of corresponding filament light source categories using established bi-directional equivalence concept. The amendment inserts new sheets H9_LEDr/1 to 7, H10_LEDr/1 to 7, HB3_LEDr/1 to 7, and HIR2_LEDr/1 to 7 into Annex 3, updates the Status table, and amends Group 5 in para. 3.3. to include the new categories.

Proposal to amend para. 6.24.9.2. to clarify that approved lamps emitting white light, rear position lamps, parking lamps, side-marker lamps and end-outline marker lamps may be switched ON as exterior courtesy lamps, and that paragraphs 6.24.9.3., 6.24.9.4., and the conditions of paragraphs 5.11. and 5.12. are not applicable to these approved lamps. The clarification confirms that paragraph 6.24.9.2. allows the coexistence and simultaneous operation of approved lamps without re-classifying them as exterior courtesy lamps and without subjecting them to exterior courtesy lamp-specific concealment requirements.
