SLR will deliver Stage 2/Step 2 to GRE-96 by end of January 2027 for submission to WP.29 in November 2027. SLR’s mandate ends December 2027. A new informal working group on Supporting technical experts on Lighting Regulation (SteLR) will be established, chaired by EC and vice-chaired by Germany, to address remaining open points from SLR and TF-GP. Main topics include visibility of signalling functions, glare prevention, apparent surface, energy saving, replaceability and sustainability, and V2X communication.

• Amend Table 21 row 13,
• Delete Notes to Table 21,

The document discusses amendments to UN R149 regarding road illumination device requirements. Illuminance and light intensity requirements have been amended multiple times over 16 years. The basis for type approval was adapted to 13.2 volts, increasing required values by approximately 40 per cent. In the 01 series, maximum values at 50L increased by a factor of 4 to improve visibility and pedestrian recognition. On dual carriageways, headlamp illuminance should exceed 8 lx@25m in point E50R/L and 16 lx@25m in point E75R. On motorways, E75R should exceed 36 lx@25m with half those values in E50L. However, increased light intensity increases glare risk for oncoming vehicles, particularly with levelling changes due to load.

Annotated provisional agenda for GRE’s ninety-fifth session (20-23 October 2026). The session will address development of UN Global Technical Regulations and Rules; simplification of lighting and light-signalling UN Regulations; amendments to UN Regulations Nos. 48, 53, 74, 86, 148, 149, 150, 10 and 65; activities of informal working groups and task forces on simplification, light sources, electromagnetic compatibility, glare prevention, and autonomous vehicle signalling; International Whole Vehicle Type Approval and electronic database developments; and election of officers for 2027.

Proposal to prohibit to approval of a manufacturer logo: insert a new para. 5.12.1.4. permitting the remaining non-substituted part of a front position lamp to remain switched on when part of it is substituted with an adjacent adaptive front-lighting system lamp, provided the distance to the closest energized AFS lighting unit fulfils the requirements of para. 5.7.2.1., amend para. 5.30.1. to improve language on logos for light-signalling devices approved to UN R148, and insert a new para. 4.5.4. to clarify that the apparent surface of a lamp shall not include a manufacturer logo built by transparent or non-transparent components that influence the propagation of light emitted.

Proposal to amend para. 3.7.1.2.1. of Annex 8 to correct the introductory text of the paragraph, which mistakenly used the 00 series wording in the 01 series of amendments. The correction updates the introductory text to reflect that in the 01 series class D was removed and classes C and V were introduced, whereas the current text includes class D and does not mention classes C and V.

• Amend para. 3.1.2.2.3. to remove reference to footnote 2,
• Amend para. 4.17. to update referenced paragraphs,
• Amend Annex 5 para. 3.5.1. to delete incorrect citation,
• Revise Annex 14 to delete AFS description form No. 1 and simplify footnote 2 by removing items (a), (b), (c), (d) and (e).

The Homework Team on ADB/AFS status report to the GRE Taskforce “Glare prevention” documenting timeline activities from February to June 2026, including seven HWT meetings and three TFGP sessions. The team listed system descriptions, benefits, disadvantages, conducted literature review, identified elements causing glare, negative effects to ADB/AFS performance, and improvable requirements. The team drafted recommendations addressing enforcement of headlamp cleaning, reduction of 2000lm limit, manual override requirements, improved detection and camera specifications, motorway ADB usage, cleaning systems, beam pattern dimming, and adaptive beam patterns for various driving conditions.

• 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 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.

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.

The HWT analyzed literature and expert knowledge to identify glare causes, performance negative effects, and improvable requirements for ADB/AFS systems. Key issues include wet road conditions, external objects obstructing sensors, soiled headlamps, and insufficient dynamic masking accuracy. Recommendations include improving headlamp cleaning enforcement, enhancing vehicle detection requirements, introducing motorway ADB usage, implementing adaptive cut-off lines, and providing manual override instructions.

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 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 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.
