Proposal to add editorial corrections to UN R48 series 06 to 09 based on GRE/2024/21/Rev.1 and WP.29/2025/114. Changes include inserting definitions for direction indicator projector, basic element, and direction indicator projection; adding requirements for direction indicator projections

Proposal provides an alternative proposal to GRE/2024/12 Revision 2 as amended by GRE-93-28 Revision 1 .

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.

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

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 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.

Baseline document for stage 2 of UN Regulation No. 48, based on R48-09 (R48-08 up to Supplement 04 and WP.29/2024/28, WP.29/2025/36, with modifications agreed at GRE-92 and GRE-93

Proposal for a supplement to the 06/07/08/09 series of amendments to UN Regulation No. 48 and the 02 series of amendments to UN Regulation No. 148 concerning manufacturer logos in side-marker lamps. The proposal amends paragraph 5.5.5. of UN R48 to clarify that no restrictions apply to logos in side-marker lamps, and amends paragraph 4.5.5. of UN R148 to add side-marker lamps to the list of lamps that shall not incorporate a logo. The justification references ECE/TRANS/WP.29/GRE/2020/5/Rev.2.

TF LUPC proposal based on UN R48 consolidate version from SLR-73-07/Rev.1 including LUPC-01-03. Adds new annex for Technical Provisions for Energy Status Indicator

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.

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.

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.

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).

This document addresses rear direction-indicator lamps mounted at low positions on vehicles. Republic of Korea reports increased public petitions and media articles regarding visibility and recognition concerns, particularly in congested traffic and for vehicles with higher driver seating positions like SUVs. UN Regulation No. 48 specifies direction-indicator lamp height requirements: not less than 350 mm and not more than 1,500 mm, or up to 2,100 mm under certain structural conditions. The presentation seeks feedback on similar issues from other countries and manufacturers.

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.
