For light sources with integrated electronics an “Electronic light source control gear” comprises components between the supply and the light emitting elements. The definition was derived from IEC and CIE, where a light source is the light emitting element. Provisions for “Electronic light source control gear” are normally used in installation and device regulations, but create confusion in relation to light sources with integrated electronics. Therefore, it is proposed to tune this term to the use in installation and device regulations and no longer specifically mention integration (or not) in the light source; “Electronic light source control gear” is not defined in R.E.5., but is part of the light source definition. The proposal also delete the term “igniter” because it is not used in the regulation.

Proposal from the SLR informal group to introduce into the 01 series of amendments to UN R53 references to the headlamp Classes in the 01 series of amendments to UN R149.

Proposal from the SLR informal group to introduce into the 02 and 03 series of amendments to UN R53 references to the headlamp Classes in the 01 series of amendments to UN R149.

Proposal from the SLR informal group to introduce into the 01 and 02 series of amendments to UN R74 references to the headlamp Classes in the 01 series of amendments to UN R149.

Proposal from the SLR informal group to introduce into the 06 series of amendments to UN R48 the possibility to extend to some additional contributors for the driving-beam (more than four) without AFS.

For a more efficient discussion during the 83rd session of GRE the experts from the International Organization of Motor Vehicle Manufacturers merged documents GRE/2020/08-Rev.1 (SLR) and GRE/2020/23 into one document.

Proposal to add a reference to the installation parameters of the licence plate illumination lamps determined during their type approval process. Every type-approved device or pair of devices have their own geometrical position in relation to the rear registration plate which is determined based on the illumination levels, maximum gradient value, angles of visibility and light incidence angle. This proposal would introduce a reference to these parameters in UN R48.

Proposal to introduce new requirements for headlamp levelling, in particular on the vertical inclination in relation to the dipped-beam headlamp mounting height.

Proposal to correct cross references to definitions as modified by Supplement 2 to the 02 series of amendments.
