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

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.

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.

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 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.

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.

Identifies challenges with headlamp aiming across approval and inspection processes. Issues include determining vehicle actual load and cut-off line definition for up-down aiming, defining vehicle references and kink point location for left-right aiming, and separating aiming control from beam pattern assessment. Inspection data show rejection rates of 4.8 per cent for light duty vehicles and 2.8 per cent for heavy duty vehicles in France, with front fog lamp misalignment at 46 per cent. The document recommends reviewing approval criteria for passing-beam orientation and defining inspection procedures, equipment, and multibeam headlamp considerations.

The Task Force on Glare Prevention, Homework teams examined literature (TFGP-06-02), Periodical Technical Inspections (TFGP-07-02), ADB/AFS Regulation 48 (TFGP-07-03), and contributions from GTB (TFGP-07-04, TFGP-07-05) and CITA (TFGP-05-02, TFGP-07-07). The Task Force is preparing draft recommendations on the first step regarding retroreflective identification devices and draft countermeasures, with further recommendations on second-step glare from light signalling devices and DRL planned for October 2026.

TF GP gives a list of items for consideration by GRE

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 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.

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.

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.

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.

The Task Force on Substitutes/Retrofits reports progress on LED substitutes and retrofits. Actions completed include Step 1 on LED Substitutes and Step 2 on LED Replacements covering administrative and technical items. The Front Fog cluster H8, H16, HB4 was approved by WP29 in March 2026 and entered into force. Current focus is the High Beam cluster HB3, HIR2, H9 and H10, with technical discussions ongoing in GTB WGLS and H10 LEDr draft category sheet submitted. Market surveillance requires improvement across control points from manufacturer to road-side enforcement.

Category H10 sheet defines LED light source H10_LEDr dimensions, electrical and photometric characteristics, and measurement requirements. The LED light source shall not exceed the envelope indicated in Figure 2 and shall function in either voltage polarity. Essential characteristics include rated 12 volts, 21 watts, luminous flux 850 lm ± 15%, cap temperature maximum 100°C, and electrical current 1500 mA minimum at 12–14 V DC. The document specifies screen projection requirements using box systems, contrast requirements, and normalized luminous intensity distribution measurements in C-planes per CIE Publication 70-1987.

The document introduces a supplemental light-signaling devices concept for multiple lamp systems. A master lamp meeting all requirements may be accompanied by one or more supplemental devices without photometric requirements for the supplemental devices. An IM reference number limits the sum of all devices mounted on a vehicle to below 100. Supplemental devices require separate marking. Color, switching, failure, and installation requirements apply to all devices of a function together. The approach permits combining devices from different manufacturers with individual type approvals.

Proposal to amend the text to enable its application to ADS vehicles.

Proposal to introduce a new “call for help” signal.

Proposal to correct errors and omissions in the 01 series of amendments. Further details can be found in informal document GRE-94-02.

Proposal to clarify manufacturer logo requirements across several paragraphs: confirming that non-illuminated graphic marks are not considered logos (para. 2.1.7.); permitting vehicle manufacturers to keep the inner portion of a front position lamp active when an AFS headlamp substitutes the outer portion (para. 5.12.1.4.); improving logo language for Light Signalling Devices approved to UN R148 (para. 5.30.1.); and clarifying that Road Illumination Devices approved to UN R149 shall not include a manufacturer logo (para. 5.30.2.).

roposal to expand the application of glare-free Adaptive Driving Beam (ADB) for category L₃ motorcycles under UN R149, by introducing additional driving beam classes aligned with UN R53 motorcycle requirements and adding symmetrical passing beam-based photometric requirements below the H-H line (Table 13, Part C). Recent technological advances have made ADB electronics more practical for a broader range of motorcycles, and these amendments aim to enhance traffic safety by reducing glare while maintaining adequate rider visibility.

Proposal to introduce new LED light source categories L2 and L3 in R.E.5. Further details can be found in informal document GRE-94-12.

Proposal to amend UN R150-01 addressing three main issues. First, since the GRE-adopted proposal to delete the unique identifier (GRE-92-18) was not part of the March 2026 WP.29 submission, the regulation text requires amendment in the interim, though this may become unnecessary if merged with GRE-92-18. Second, the approval marking approach is aligned with UN R148 by including one example in the body text and referencing other arrangements in Annex 10, allowing deletion of the Table 1 reference and redundant ratio explanations from Figure A10-I. Third, the outdated requirement for function symbols to be placed diametrically opposite the approval number — inherited from UN R3 and R7 but already removed in UN R148 — is deleted from Annex 10, along with a clarifying amendment to the note below Figure A10-I to prevent inconsistent interpretations among technical services. Further details can be found in informal document GRE-94-11.

Proposal to introduce a clarification of grouped markings and labels. Further details can be found in informal document GRE-94-07.

In UN R149-01, corrections include: updating the Class W Bend Light CoP maximum at point BR to align with the type-approval table; correcting miscalculated Class R Bend Lighting CoP values; and fixing table note references in Annex 4 following the introduction of scientific notation in the 01 series.

Further details can be found in informal document GRE-94-10.

Proposal to clarify and modernize lamp installation and component requirements in UN R48 and UN R148:

• Remove the “band/strip” terminology and expand the definition of a pair of lamps to cover full-width designs
• Remove the three-device maximum for Y-lamps to ensure technology neutrality
• Add a new paragraph §5.5.5 defining a pair as a two-lamp system
• Relocate light source requirements from UN R48 to UN R148 §4.7.3 to ensure at least one light source per side
• Remove the 0.8-metre minimum length requirement
• Clarify that definitions in §2.4.10 apply only to the relevant vehicle categories
• Update provisions for light source positioning in UN R148
• Clarify §4.8.1.3 in UN R148
• Add new sampling provisions in §4.8.11 for testing band/strip lamps

Proposal to clarify the 80% failure criterion for Conformity of Production (CoP) checks by confirming that CoP tables represent a simplified subset of the full Class C type-approval measurement points, and to exclude overhead requirements (items S50 and S100 in Tables 6 and 7) from the passing beam failure detection criterion, as these may be fulfilled by position lamps. Further details can be found in informal document GRE-94-08.

Proposal to introduce selective yellow as an permitted alternative to white for front position lamps and daytime running lamps in UN R48 and UN R148. Studies confirm that selective yellow performs equally to white for oncoming vehicle recognition and speed estimation. Unlike historical filament lamp applications where a yellow filter reduced luminous intensity, modern LEDs achieve the same intensity levels without reduction. Specific amendments include: updating §5.15 to reflect selective yellow options and removing a duplicated front fog lamp requirement; amending §§6.9.7 and 6.19.7 to deactivate selective yellow position and daytime running lamps on the relevant side during direction indicator activation; and aligning UN R148 (01 series) by amending §§5.1.7, 5.4.7 and Annex 1 accordingly. The colour boundaries for selective yellow are already defined in §2.11.1.2 and require no amendment. Further details can be found in informal document GRE-94-05.

Proposal to improve the clarity and structure of Conformity of Production (CoP) requirements for driving beams in UN R149 by following the approach used in UN R123.

Proposal to exclude retro-reflective devices and markings from the requirement of “Red light to the front” and “White light to the rear”.
