Proposal to introduce new requirements for headlamp levelling, in particular on the vertical inclination in relation to the dipped-beam headlamp mounting height, to permit manual levelling only for off-road vehicles, to clarify usage of daytime running lamps (DRL) with other lamps, to improve the definition of photometric stability and provisions for visibility of red light, to introduce provisions for lighting under parked condition and for manoeuvring lamps on trailers, to enable the phasing out of the installation of older lamps and devices following the measures undertaken pursuant to the simplification of lighting regulations under GRE, to introduce technology-neutral failure provisions, and to correct and otherwise clarify the text.

Proposal from the SLR informal group to align UN R48 with the 01series of amendments to UN R149 (road illumination devices). Para. 6.2.8.2. concerns the requirement for failure tell-tale of passing-beam headlamps (presence and activation) which only covers LED modules. The amendment proposes technology-neutral language. The proposal aims to complete the requirements to enable mandatory installation of headlamps approved to UN R149.01 per the request of the European Commission.

Proposal from the task force on Substitute and Replacement lamps (TFSR) to address two alternative configurations involving differences in the “screen projection requirements” and “normalized luminous intensity distribution” based on full photometric light source equivalence and on bi-directional light source design.

Proposal to add general provisions for installation.

Proposal by the Task Force on Automated Vehicle Signalling Requirements (TF AVSR) to introduce provisions for ADS vehicles and provide lighting requirements adapted to such vehicles and operating modes. This proposal is intended to supersede GRE/2023/9/Rev.1.

Proposal to update the reference to IEC Publication 60809.

Proposal of an informal document superseding the formal document GRE/2023/17 to correct numbering.

Proposal by the experts from Germany and the Task Force on Automated Vehicle Signalling Requirements (TF AVSR) to introduce provisions for vehicles with a driving system controlling its operation or operated by driver-support features, automated driving features, or an Automated Driving System and provide lighting requirements adapted to such vehicles and operating modes.

Proposal to address vehicles of categories R or T with a width more than 2.55 m and of category S with a width more than 3 m as well as to allow using reflective materials as an alternative to retro-reflectors.

Proposal to correct a reference to the 01 series of amendments to UN Regulation No. 148.

Proposal to clarify and to correct the text of the 01 series of amendments to UN Regulation No. 148.

Proposal to clarify and to correct the text of the 00 and 01 series of amendments to UN Regulation No. 149.

Proposal to clarify and to correct the text of the 00 and 01 series of amendments to UN Regulation No. 150.

Proposals to introduce provisions for adaptive front lighting systems (AFS) for motorcycles.

Proposal to remove the failure mode and light source failure detection requirements for the cornering lamp.

Proposal to clarify usage of daytime running lamps (DRL) with other lamps.

Proposal to improve the definition of photometric stability.

In paragraph 3.1. of Annex 4, Part 1 the position of the photometer head, the reference axis and the directions are clearly described. If the surface reflection is on the opposite side of the source from the photometer head, which is given at an angle of (β1 = -5°), the surface reflection has no influence on the measurement. This is true for the measurement of RI values as well as for colour measurement.
The proposed solution is based on an existing description in UN Regulation No. 27 (namely paragraph 2.6. of Annex 6) concerning the procedure to follow in case of a surface reflection for both colour measurement and CIL measurement.

This proposal aims to remove the list of classes and to refer, in general, only to passing-beams and driving-beams.

Proposes to amend paragraph 3.3.3.3. of UN Regulation No. 37 to reflect the latest edition of IEC Publication 60809, Edition 4

Proposal to make an editorial correction to the requirements to light emitting diode (LED) light sources.

Proposal to correct wrong references and add a missing text

Proposal to introduce longer transitional provisions for heavy commercial vehicles and trailers
