Proposal to renumber and amend para. 13.3. and related subparagraphs to correct the transitional provisions of the 07 series of amendments. The existing para. 13.3.4. is renumbered to 13.3.3., the original para. 13.3.3. is renumbered to 13.3.4., and para. 13.3.4. is amended to explicitly reference vehicles and parts not equipped with or not part of an Automated Driving System (ADS). Contracting Parties shall continue to accept type approvals issued according to the 06 series of amendments for vehicles not equipped with an ADS or for vehicle systems, equipment and parts not part of an ADS which are not affected by the changes introduced by the 07 series of amendments, and for approvals first issued before 1 September 2029.

Proposal to:

• Amend para. 3.1.2.1. to renumber sub-paragraphs (a) through (e) as (b) through (f),
• Amend para. 3.1.2.2.(e) and (f) to renumber (e) as (f) and clarify requirements for adjustable reflectors and compliance with para. 4.13.1.,
• Amend para. 3.1.2.2.1.(d)(ii) to clarify that objective luminous flux shall be provided only for passing beam and to add information on electrical interface for electronic light source control gear,
• Amend para. 3.1.2.2.2.(b), (i) and (k)(ii) to remove reference to footnote 2 in para. (b), relocate mounting position requirements from para. 3.1.2.1.(a) to para. 3.1.2.2.2.(i), and add provisions for light source modules and electronic light source control gear,
• 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).

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.

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. 6.27.9.1. 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 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.

Proposal to amend para. 2.4.10. to expand the definition of a pair to include vehicles of categories M, N and O with one or more lamps extending from left to right; amend para. 2.4.11. and its sub-paragraphs to redefine single and multiple lamps to refer to interdependent lamps marked “Y”; amend para. 2.4.12. to redefine interdependent lamp system and add definition of interdependent lamp marked “Y”; amend para. 5.5. and its sub-paragraphs to add that a pair shall be considered as two lamps and to establish requirements for manufacturer logos; amend para. 5.7.2.2.; amend para. 5.7.2.3.; delete para. 5.7.2.4.; amend para. 5.18.2.; add new para. 4.7.3. to UN Regulation No. 148 to require that a pair containing one or more light emitting surfaces extending from left to right shall contain at least one light source on each side; and amend para. 4.8.1.3. to clarify photometric measurement procedures.

Proposal to amend para. 5.10.3. to exclude retro-reflective devices, retro-reflective markings, lighting devices fitted for interior lighting, and reversing projections from the requirements for “red light to the front” and “white light to the rear”. The proposal aims to eliminate unnecessary testing burdens on functions that never emit light by themselves and would always meet the emission requirement of less than 0.25 cd by definition. The exemption aligns with Vienna Convention provisions and reflects an original intent from over twenty years prior.

Proposal to amend para. 4.5.5.(d) to clarify that stop lamps, direction indicator lamps, reversing lamps and side-marker lamps shall not incorporate a manufacturer logo. The amendment addresses an unintended gap in the regulations whereby side-marker lamps could theoretically be approved with a manufacturer logo, whereas it had never been the intention of GRE to allow side-marker lamps with a manufacturer logo. Contracting Parties agreed during the April 2026 session that an amendment to clarify this would be appropriate.

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.

Document describes the current answer-back signal requirement in UN R48-09, which limits maximum luminous intensity to 700 cd on or above the HH line. The regulation practically prohibits use of direction indicators with filament bulb light sources as answer-back signals, despite conventional widespread use without safety issues. Japan proposes excluding direction indicators from the 700 cd limitation to allow conventional answer-back signals using direction indicators with filament light sources, while maintaining other restrictions including the 700 cd limitation for other functions and prohibition of front fog lamps, rear fog lamps and stop lamps as answer-back signals. Revision is needed before UN R48-09 mandate for new vehicles in September 2027.

This paper provides additional information and justification regarding document GRE/2026/19, introducing four new LED replacement light source categories: H9_LEDr, HIR2_LEDr, HB3_LEDr, and H10_LEDr. All proposals were developed considering equivalence criteria including photometric, thermal, and electrical performance. H9_LEDr, HIR2_LEDr, and HB3_LEDr address high beam applications, while H10_LEDr completes the front fog applications set. The H9_LEDr proposal specifies a single luminous flux of 1875 lm at 13.2V to accommodate both high-beam-only and bi-functional applications.

Proposal to add a footnote to the Scope stating that nothing in the regulation prevents a Party from prohibiting the application of these lamps, renumber para. 10.5. as 10.6., and amend para. 10.6.1. to require all ADS Marker Lamps installed on the vehicle to be automatically switched ON by the ADS when performing the DDT, to be switched OFF when conditions no longer exist, to always allow independent switching ON and OFF from all other lighting functions, and to not be switched ON when an ADS performs the DDT in a country that does not allow the use of ADS Marker Lamps.

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.

The 76th SLR session (4–6 February 2026) reviewed and improved baseline documents for Regulations 48, 53, 74, and 86 for Stage 2/Step 2 submission to GRE-94 as informal documents. SLR approved simplification of paragraphs 6.×.4. and 6.×.5. in Reg. 48 and agreed on technological neutrality amendments to Reg. 48 and a compromise text for Reg. 149. SLR approved a compromise text on “Prohibited if not allowed” for final check at SLR-77. Discussions on apparent surface and direction indicator visibility will resume at SLR-77. Transitional Provisions for the 10 series will be reviewed at SLR-77. The 77th, 78th, and 79th meetings are scheduled for April, June, and September 2026.

At the 77th SLR meeting (Brussels, April 2026), participants reviewed and improved baseline documents for UN Regulations 48, 53, 74, and 86, reflected in SLR-77-08/Rev.1, SLR-77-09, SLR-77-10, and SLR-77-07 respectively. SLR approved a revised proposal to correct errors in Reg. 150-01 (SLR-77-06/Rev.1, superseding GRE-94-02) and a compromise text prohibiting additional lamps unless complying with national requirements. SLR agreed to postpone official document submission to GRE-96 (April 2027) and will submit 11 informal documents to GRE-94, including status report, four baseline documents, four highlights slides, a proposal on technological neutrality, and the revised correction proposal. Discussions on apparent surface, direction indicator visibility, and direction indicator lamp height will resume at SLR-78 (June 2026).

Task Force on Lamps Under Parked Conditions held its 11th session on 8–10 June 2026 in Paris. The agenda and previous report were adopted without changes. Experts reviewed proposals for modifications to UN R48, discussing energy status indicator colour conventions, apparent surface requirements, numbers of indicators for multiple charging connectors, and lamp test modes. Key decisions included restricting indicator illumination to connectors in use, maintaining 1–25 cm² apparent surface for most indicators with 1–150 cm² for connector-surrounding indicators, and performing one mode test per class in neutral state. The next meeting is scheduled for 11 September 2026 in Tokyo, with a final proposal targeted for April 2027 GRE session.
