Proposal to clarify manufacturer logo requirements across several paragraphs: confirming that non-illuminated graphic marks are not considered logos (para. 2.1.7.); permitting vehicle manufacturers to keep the inner portion of a front position lamp active when an AFS headlamp substitutes the outer portion (para. 5.12.1.4.); improving logo language for Light Signalling Devices approved to UN R148 (para. 5.30.1.); and clarifying that Road Illumination Devices approved to UN R149 shall not include a manufacturer logo (para. 5.30.2.).

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 exclude retro-reflective devices and markings from the requirement of “Red light to the front” and “White light to the rear”.

Proposal to introduce a new “call for help” signal.

Proposal to align the Exterior Courtesy Lamps provisions of the 08 series amendments with those of the 09 series.
