Draft proposal from the SLR informal group to show the latest status of work and collect feedback from GRE to be used in the preparation of the final proposal that will be submitted to the 84th GRE session.

Proposal to correct the omission of the provision for detection of failure of a light source and/or a LED module in an Adaptive Front Lighting System in UN 149 as provided for in UN R123. The proposal would align UN R149 with UN R123.

Proposal to correct an error introduced by the 01 series of amendments to UN R113 when angular coordinates were introduced instead of dimensions in mm with screen at 25 m. The same correction applies to the 02 and 03 series of amendments to UN R113 and to UN R149. The proposal also corrects Annex 3, Figure C of UN R113 where the description of the zone 1 is not in line with the photometric requirements set in paragraph 6.2.5.2. which defines the horizontal angles to 5° to the left and 5° to the right. Similarly, the proposal corrects Annex 4, Figure A4-IX of UN R149 where the description of the zone 1 is not in line with the photometric requirements set in paragraph 5.4.4.2. Table 34 which defines the horizontal angles to 5° to the left and 5° to the right for the class BS headlamps.

Per UN R981 R112, and R123, proposals to:

• Rename the element “Segment I C to D” in Table 8
• Amend the luminous intensity requirements in Table 9, Part B and
• Correct Annex 7, paragraph 2.1.2.2.1. (a)

• Rename “E_max R/L” in Table 8
• Change Annex 7, paragraph 1. d).

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.

Proposal aim to allow the installation of Adaptive Driving Beams (ADB) on vehicles of category L₃.

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.

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.
