Proposal to clarify and modernize lamp installation and component requirements in UN R48 and UN R148 to address the growing variety of vehicle and lamp designs, particularly band/strip lamps extending across the full width of the vehicle. Key changes include: removing the “band/strip” terminology and expanding the definition of a pair of lamps to cover full-width designs; removing the three-device maximum for Y-lamps to ensure technology neutrality; adding a new paragraph §5.5.5 defining a pair as a two-lamp system; relocating light source requirements from UN R48 to UN R148 §4.7.3 to ensure at least one light source per side; removing the 0.8-metre minimum length requirement; and clarifying that definitions in §2.4.10 apply only to the relevant vehicle categories. Minor amendments to UN R148 include updated provisions for light source positioning, clarification of §4.8.1.3, and new sampling provisions in §4.8.11 for testing band/strip lamps. Further details can be found in informal document GRE-94-03.

Proposal to introduce selective yellow as an permitted alternative to white for front position lamps and daytime running lamps in UN R48 and UN R148. Studies confirm that selective yellow performs equally to white for oncoming vehicle recognition and speed estimation. Unlike historical filament lamp applications where a yellow filter reduced luminous intensity, modern LEDs achieve the same intensity levels without reduction. Specific amendments include: updating §5.15 to reflect selective yellow options and removing a duplicated front fog lamp requirement; amending §§6.9.7 and 6.19.7 to deactivate selective yellow position and daytime running lamps on the relevant side during direction indicator activation; and aligning UN R148 (01 series) by amending §§5.1.7, 5.4.7 and Annex 1 accordingly. The colour boundaries for selective yellow are already defined in §2.11.1.2 and require no amendment. Further details can be found in informal document GRE-94-05.

Proposal to introduce a clarification of grouped markings and labels. Further details can be found in informal document GRE-94-07.

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.

Proposal to replace “multiple separate light sources” with “multiple light sources” in the provision governing rear position lamps reciprocally incorporated with stop lamps.
