Proposal to simplify definitions in para. 2, consolidate general specifications in para. 5 and individual specifications in para. 6, revise failure provisions and EV inclusion criteria, clarify wording where no front position lamp exists, and correct references in regulation 53-04. Changes include updating terminology for consistency with UN R48 baseline document (type-approved, retro-reflector, power-driven, direction-indicator lamp with hyphens), replacing visual failure tell-tale with tell-tale indicating failure, using RECAS instead of rear-end collision alert signal, standardizing vehicle category designations, applying scientific notation aligned with prior amendments, consolidating communication forms, reducing transitional provisions to latest only, and modifying paragraph 6.×.4 and 6.×.5 simplifications.

GRE-IWG SLR presents baseline amendments to UN R74 series 04. The document highlights main improvements including simplification of definitions in para. 2 by deleting common definitions shared with UN R48, deletion of six definitions resulting in six remaining, terminology and format alignment with UN R48 and UN R53, addition of a summary table of lamp positioning and geometric visibility angles, amendments to align with other installation regulations including failure provisions and electric vehicle inclusion, simplification of para. 6.×.4. and 6.×.5., retention of only the latest transitional provisions with previous ones moved to a reference document, and provision of editable pictures.

The Task Force on Glare Prevention presents recommendations to address glare from headlamps. Regulatory considerations include introducing adaptive cut-off lines, mandatory dynamic auto-levelling, Motorway Adaptive Driving Beam mode requirements, beam dimming for wet roads or urban areas, lowered maximum headlamp installation heights, improved automatic high-beam switching and ADB requirements, and maximum low-beam intensity limits. Additional recommendations address headlamp cleaning devices under UN R45, driver reminders, and user manual instructions. PTI-related considerations cover vehicle weight influence, floor evenness, cut-off line definitions, and coordination between type approval and inspection requirements. General considerations include driver instructions for ADB manual override and investigation of aiming differences. Actions beyond GRE mandate address illegal products, driver awareness, and infrastructure improvements.

SLR will deliver Stage 2 / Step 2 to GRE-96 as official package by the end of January 2027. If adopted, it will be submitted to WP.29 in November 2027. SLR’s mandate will end in December 2027. Open points and subjects requiring further discussion will be addressed in a new IWG with new ToR, merging remaining open points from SLR with TF-GP and other important subjects. A new IWG on Lighting Performance will be established with EC as Chair, Germany and S. Korea as Vice-chairs, and GTB as Secretariat.

Proposal for uniform provisions concerning approval of ADS marker lamps for power-driven vehicles and their trailers, and approval of vehicles with regard to installation of ADS marker lamps. Covers component approval requirements including luminous intensity, colour, and light distribution for front, rear, and side ADS marker lamps, and vehicle installation requirements including position, geometric visibility, electrical connections, and conformity of production procedures.

Report of the 34th meeting of the GRE Taskforce on Autonomous Vehicle Signalling Requirements held on 22 September 2026. The group reviewed a draft proposal hybrid regulation for ADS marker lamp after an editorial meeting, going through the entire document and deleting unnecessary comments. Para. 9.26 regarding substitution will be placed in square brackets for further discussion at GRE, as Japan opposes it due to lack of scientific evidence. Paragraphs 10.6.2. to 10.6.5. regarding reciprocal incorporation with direction indicators were reworked, and justification text requires further development for the formal proposal. Document AVSR-34-02 will be sent to GRE-95 as an informal document.

The Task Force on LED Substitutes and Retrofits reports on establishing a type-approval framework for LED replacements to enable safe technology transition from incandescent to LED lighting for cars-in-use. Step 1 completion has resulted in growing LED replacement category sheets in RE5, with national and UN approvals enabled. Step 2 requires improved market surveillance, as unsafe non-approved products reach roads and some R37-approved products show non-compliance. The task force proposes waiting for front fog cycle completion and applying lessons learnt before enforcing the high beam package, addressing keying deficiencies and inadequate warnings on unapproved products. Market surveillance control points span approval, import, point of sales, PTI, and roadside enforcement.

Input provided by experts from the GRE TF S/R concerning market surveillance needs for LED replacement light sources. LED replacement light sources enable technology transition from incandescent to LED for vehicles in operation, offering longer lifetime, higher vibration resistance, and lower power consumption. Type-approval framework for LEDr has been established through national approvals and UN R37 approvals. Market surveillance must be improved to ensure only safe, compliant LEDr with type approval are used on public roads. Products without type approval should be offered with correct consumer information and clear restriction for off-road use only. Authorities should remove non-compliant products without type approval if used on public roads.

Status report of the Task Force on Substitutes/Retrofits covering LED replacement light sources. The task force recommends deferring submission of high beam category sheets to WP29 pending completion of the front fog cluster PDCA cycle. Two guidance documents will be developed over the next six months to clarify UN R37 requirements for LED replacements and their relationship to IEC 60061. Market surveillance improvements are being pursued through coordination with authorities and PTI organisations.
