The proposal opens the opportunity to project driver assistance symbols on the road ahead the vehicle as part of the Adaptive Driving Beam by introducing angular limits for the placement of these projections as well as luminous intensity limits in order to guarantee a good perceptibility of the symbols for the driver at night time without distracting other road users.

Discussion on the benefits to VRU road safety provided by projections combined with turn indicators and/or reversing lamps and request for guidance implementing SRP provisions in existing UN Regulations.

Proposal to extend to AFS passing-beam headlamps the possibility to project driver assistance symbols and patterns.

Proposal to extend to AFS passing-beam headlamps the possibility to project driver assistance symbols and patterns if the pertinent requirements of UN R149 are fulfilled.

Revised proposal to avoid exceeding the aggregate maximum intensity of the main-beam headlamps (430,000 cd) by removing the double requirement for a sum of reference marks and a sum of maximum luminous intensities which risks generating large rounding errors when the maximum luminous intensities are summed up.

Proposal to introduce the provisions to enable the use of light-signalling in form of projection of patterns on the road for other road users through new light-signalling functions “Direction indicator projection” and “Reversing projection”.

Chinese questions submitted at the 90th GRE session (doc. GRE-90-29)

Reversing projection Supporting information to the proposal GRE/2024/20 Proposal for a Supplement to the 01 series of amendments to UN Regulation No. 148 and to the 06, 07, 08 and 09 series of amendments to UN Regulation No. 48

Supporting information to the proposal GRE/2024/21 Proposal for a Supplement to the 01 series of amendments to UN Regulation No. 148 and to the 06, 07, 08 and 09 series of amendments to UN Regulation No. 48

Proposal to introduce provisions to enable the approval of reversing light projections.

Proposal to introduce provisions enabling the approval of reversing light projections.

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 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 to editorially correct approved proposal GRE/2024/21/Rev.1 and WP.29/2025/112. Editorial corrections amend paragraph 1 to include reversing projectors and direction indicator projectors in scope. New paragraph 3.1.2.10 requires drawings showing relative position of direction indicator projector and lamp. Tables 1 and 2 are amended to add reversing projector and direction indicator projector entries.

Survey of Vulnerable Road Users associations on Direction Indicator Projection, Independent third-party research from six countries confirms safety benefits and lack of confusion and analysis shows most VRU collisions occur in urban areas near junctions during vehicle turning.

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.

Proposal to clarify the definitions of type with regard to manufacturer, trade names and marks.
