Draft technical specifications establish mandatory ADS marker lamps on motor vehicles of categories M₁–M₃, N₁–N₃, L₆, and L₇, with front and rear lamps mandatory and side lamps mandatory or optional depending on vehicle length. Front lamps require daytime photometry of 50–300 cd and nighttime 10–125 cd; rear lamps require 20–120 cd daytime and 4–42 cd nighttime. Side lamps vary by type. All lamps are blue-green turquoise, mounted at minimum 250 mm height, and activate automatically only in fully automated mode with manual switching prohibited.

Based on AVSR-31-03_Rev.2 and GTBWGSL 7201, this work-in-progress draft proposes a new UN Regulation for ADS Marker Lamps. The proposal applies to vehicles of categories M, N, L₆, L₇, and O. It establishes approval procedures for ADS Marker Lamp components and vehicle installation requirements if fitted on a vehicle (the draft includes a tentative statement that nothing prevents prohibiting the use of ADS marker lamps). Key provisions include luminous intensity requirements with day-time and night-time levels for front (AMF), rear (AMR), and side (AMS) lamps; blue-green colour specifications; approval marking and labelling requirements; geometric visibility angles; electrical connections ensuring automatic activation when automated driving systems perform the dynamic driving task; and conformity of production procedures. Outstanding discussion items requiring guidance include vehicle category applicability, day-time and night-time condition definitions, reciprocal incorporation with direction indicators, alternative roof-mounted lamp options, and specification details for side marker lamp categories. Testing procedures for light sources and automatic switching conditions between day-time and night-time modes are included in annexes.
