The agenda includes corrections to UN R150-01, baseline documents for UN R53, R74, R86, and R48, simplification of paragraphs 6.×.4 and 6.×.5, transitional provisions, harmonisation of requirements, apparent surface considerations, and direction indicator visibility improvements. The next meetings are scheduled for June and December 2026, with a potential September 2026 session in Tokyo.

Proposal to insert new definitions for “direction indicator projector,” “basic element,” and “direction indicator projection” in paragraph 2.5.22., 2.7.12., and 2.7.13.; amend paragraph 5.9.1. to include direction indicator projections as flashing lamps; amend paragraph 5.15. to specify amber colour for direction indicator projection; insert new paragraph 5.37. with general provisions for direction indicator projections; insert new paragraph 6.28. with detailed requirements for direction indicator projection presence, number, arrangement, position, projection area, orientation, electrical connections, and other requirements for vehicles of categories M, N, O₃, and O₄; insert new item 9.32. in Annex 1 with communication form entries; amend Annex 14 title; and insert new Annex 18 (Basic element to be used for direction indicator projection patterns).

GTB proposes simplifying UN R48 by developing a single CAD-based method to determine apparent surface at early design stages. The proposal deletes the “light-emitting surface” definition and establishes “apparent surface” as the orthogonal projection of visible light-emitting surfaces in a specified observation direction. Amendments include revised definitions for lens, textured outer lens, illuminating surface, and apparent surface, with modified requirements for single lamps with multiple distinct parts. Distance requirements between adjacent parts are adjusted to 75mm or 200mm depending on lamp type.

UN R48 baseline text for a 10 series of amendments proposes uniform provisions for vehicle lighting and light-signalling device installation approval. The document consolidates modifications agreed at working group session through dated amendment documents and resolutions. Pending issues include determining “[any] subsequent series” terminology for frozen regulations, renumbering and cross-checking paragraphs, addressing apparent surface visibility, improving daytime running lamp visibility against stop lamps, resolving “prohibited if not allowed” language, and numbering all figures with titles. Editorial polishing includes standardizing hyphenated terminology (“driving-beam,” “passing-beam,” “retro-reflector,” “direction-indicator lamp”), applying consistent UN Regulation references, replacing “communication sheet” with “communication form,” assigning table and figure numbers consistent with similar regulations, and correcting percentage notation to “per cent.”

The European Cyclists Federation and International Federation of Pedestrians withhold support for Direction Indicator Projection (DIP) technology regulation. They contend available studies lack evidence of reduced conflicts or crashes in real-world conditions, raise concerns about behavioral adaptations that may redistribute rather than reduce risk, and note the technology does not address responsibility allocation where cyclists and pedestrians already have legal priority. Additional concerns include reliance on uncontrolled road surfaces affecting signal visibility and clarity, and risks of shifting safety burden onto vulnerable road users contrary to Safe System principles. They urge contracting parties to refrain from regulation pending robust research confirming the technology neither undermines priority rules nor introduces unintended behavioral risks.

FIA proposes that vehicles in automated mode in mixed traffic should be marked with one light visible from all sides. Marker lights should have uniform colour and shape clearly distinguished from other signal lights, be positioned at sufficient distance from signal lights and headlamps to avoid impairing visibility, and be designed to not glare other road users.

Proposal to amend paragraph 5.2.3.3 to clarify that samples shall be subjected to the heat resistance test described in Part 1 of Annex 6, prior to the tests described in Parts 1 and 2 of Annex 6 paragraphs 5.2.5 and 5.2.6. Proposal to amend paragraph 5.1.7 to correct the reference in Tables 4 and 5 from Part 4 to Part 5 of Annex 6 for the Rear face test. Proposal to amend Annex 5, paragraph 8.1.4 to correct the cross-reference from paragraph 5.9.4.2.1 to paragraph 5.3.4.2.1.

This status report from GRE TF AVSR discusses development of a Hybrid Regulation on ADS Marker Lamps for power-driven vehicles. The TF addresses colour specifications aligned with SAE J3134 and ECE R65 standards. Key open questions for GRE guidance include: whether pulsating luminous intensity patterns should be permitted; potential conflict with the 1968 Vienna Convention on Road Traffic; application to platooning trucks and agricultural vehicles; inclusion of L₆ and L₇ categories; mandatory versus optional rear installation; variable luminous intensity based on environmental conditions; side marker lamp integration possibilities; and reciprocal incorporation with other lamps.

Proposal to insert new paragraph 5.3. into UN R178 (Emergency Lane Keeping Systems). The new paragraph requires that the effectiveness of ELKS shall not be adversely affected by magnetic or electrical fields, demonstrated by fulfilling technical requirements and respecting transitional provisions of the 06 or any subsequent series of amendments to UN R10. This proposal aims to ensure Electromagnetic Compatibility and make the reference future proof for potential ELKS requirements in future series of amendments to UN R10, based on GRVA-24-05/Rev.2.

Proposal to amend UN Regulation No. 10 (Electromagnetic Compatibility) through a Supplement to the 07 series of amendments to fit Automated Driving System requirements. The proposal introduces new paragraphs defining ADS and ADS test configuration; amends paragraph 1.3 to include ADS control; expands paragraph 2.12 on immunity-related functions to cover ADS sensor performance; deletes paragraphs 2.26 and 2.27; adds paragraph 6.11.3 on special ADS requirements; and introduces an “Active ADS Mode” test table in Annex 6 paragraph 2.1.1.2, establishing test conditions for vehicles with active ADS features performing the Dynamic Driving Task.

The document discusses transitional provisions for UN R10.07 series amendments, which entered into force June 2025. Contracting Parties shall not refuse type approvals under the 07 series amendments. As from 1 September 2029, Contracting Parties need not accept type approvals under preceding series first issued after that date, but shall continue accepting those first issued before that date for vehicles, vehicle systems, equipment, and parts not affected by changes introduced by the 07 series amendments. The document references ECE/TRANS/WP.29/1044 rev3 for general transitional provision guidance. Nearly all vehicles and ESAs will not be granted extensions for UN R10.06 after 1 September 2029, except those complying only with broadband emissions.

Proposal to add work lamp definitions and requirements to UN R48, minimum height of 250 mm above ground, downward orientation, and automatic deactivation within 1 second if vehicle speed exceeds 15 km/h. Work lamps require independent manual controls and a mandatory visual operating tell-tale. Annex 1 adds item 9.32. for work lamp approval documentation.

Proposal to correct mistakes found in the current 04 series of amendments and align with UN R48, with appropriate adaptation of L category vehicles.

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.
