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.
