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.
