Proposal to introduce the following changes into the draft new Regulation on light-signalling devices:

1. Use of LED substitute light source(s) is allowed and does not constitute a change of the lamp type. However, lamp performances shall be tested during type approval also with the LED substitute light source. Approval of the lamp using filament light source(s) is a prerequisite for approval of the lamp using LED substitute light source(s).
2. COP testing of the lamp is required with an (etalon) filament light source only, because the LED substitute is the counterpart light source of the filament light source, resulting in equivalent photometrical lamp performance. The quality i.e. the equivalence to the filament light source, is controlled in R128.
3. Use of LED substitute light sources is at the discretion of the applicant, who shall declare this use, if any, to the Approval Authorities at the time of application for the first lamp approval or subsequent extension of approval issued for the version using the LED substitute light source.
4. The use of LED substitute light source(s) in a certain lamp type shall be indicated on the lamp by marking of the LED substitute light source category, in addition to the marking of the filament light source of which the LED substitute light source is the counterpart.
   
   This marking on the lamp will be used for checking the allowance for use of lamps with LED substitute light sources in application of the Regulation on lamps installation on vehicle.
5. In case a lamp with colour filter(s) is approved for using LED substitute light source(s), this lamp shall be marked “G” to indicate that this lamp shall be equipped with LED substitute light source(s) marked “G” for colour and luminous intensity quality reasons.
6. The indication of both the filament light source and of its LED counterpart light source, if any, shall be explicitly provided in the communication form.

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 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”.

This document replaces the official document ECE/TRANS/WP.29/GRE/2024/6

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

Proposal to introduce provisions enabling the approval of reversing light 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.

Proposal to correct and clarify the communication form.

Proposal aims to correct a wrong reference for the determination of the approval marking size.

Proposal aims to introduce reversing projections. This proposal intends to introduce the possibility of light-signalling, in form of projection of patterns on the road, for other road users through new light-signalling function
“Reversing projection”.
Proposal also applies for a Supplement to the 06, 07, 08 and 09 series of amendments to UN Regulation No. 48

Proposal aims to introduce Direction Indicator Projections. This proposal intends to introduce the possibility of light-signalling, in form of projection of patterns on the road, for other road users through new light-signalling function “Direction indicator projection”.

Proposal to correct an editorial error regarding the markings for light source control gear.

Proposal to clarify the calculation method (i.e., rounding down to three digits) for the acceptance criteria in cases where tolerance limits are calculated.

Proposal to clarify and modernize lamp installation and component requirements in UN R48 and UN R148:

• Remove the “band/strip” terminology and expand the definition of a pair of lamps to cover full-width designs
• Remove the three-device maximum for Y-lamps to ensure technology neutrality
• Add a new paragraph §5.5.5 defining a pair as a two-lamp system
• Relocate light source requirements from UN R48 to UN R148 §4.7.3 to ensure at least one light source per side
• Remove the 0.8-metre minimum length requirement
• Clarify that definitions in §2.4.10 apply only to the relevant vehicle categories
• Update provisions for light source positioning in UN R148
• Clarify §4.8.1.3 in UN R148
• Add new sampling provisions in §4.8.11 for testing band/strip lamps

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.
