Proposal from the Simplification of Lighting Regulations informal group to combine provisions of UN Regulations Nos. 4, 6, 7, 23, 38, 50, 77, 87 and 91 into a single regulation. This consolidation aims to streamline the administration and implementation of these lighting regulations while setting the foundation for a future shift towards performance-based approval requirements. This proposal restructures the existing body of lighting regulations without changing their content (e.g., technical requirements).

Proposal from the Simplification of Lighting Regulations informal group to consolidate common definitions of terms concerning lighting, light signalling, retro-reflective devices and device installation into Regulation No. 48. (Definitions specific to particular devices would be maintained in the respective device regulations.)

Proposal from the Simplification of Lighting Regulations informal group to introduce references to the three new simplified Regulations (Light-Signalling Devices (LSD), Road Illumination Devices (RID) and Retro-Reflective Devices (RRD)) into Regulation No. 48.

Proposal from the Simplification of Lighting Regulations informal group to introduce transitional provisions for the phasing out of the existing Regulations on lighting and light-signalling in conjunction with the introduction of three new simplified Regulations on Light-Signalling Devices (LSD), Road Illumination Devices (RID) and Retro-Reflective Devices (RRD).

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.
5. 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.
6. 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.
7. 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.

Proposal to introduce requirements for replaceable light-emitting diode (LED) light sources for forward lighting in the new Regulation on Road Illumination Devices (RID). As the Informal Working Group “Simplification of the Lighting and Light-Signalling Regulations” (IWG SLR) continues working on the new RID Regulation, it is not possible to indicate all detailed modifications that will be required to incorporate the replaceable LED light sources for forward lighting. However, in general, only simple editorial changes will be required. Further work is required to identify the changes that will be required in the annexes.

Request to delete the amendment to paragraph 3.3.4.1.1. in the proposal to introduce requirements for the use of light-emitting diode substitute light sources in the new Regulation on Light-Signalling Devices. The proposed amendment was included in the submission by mistake.

Proposal to reinsert text in paragraph 1.3 concerning differentiation of types according to trade name or mark that was inadvertently omitted from Supplements 27 and 28 to the 01 series of amendments.

Revised proposal, superseding document GRE/2017/11, from the Simplification of Lighting Regulations informal group to introduce references to the three new simplified Regulations (Light-Signalling Devices (LSD), Road Illumination Devices (RID) and Retro-Reflective Devices (RRD)) into Regulation No. 48.

Proposal from the special interest group of experts for DRL-L to introduce requirements for automatic switching from daytime running lamps (“DRL”) to headlamp(s) if maximum luminous intensity of DRL is above 700 cd.
