This intermediate draft proposes a new UN Regulation on ADS Marker Lamps based on discussions in technical groups. The regulation establishes requirements for approval of ADS Marker Lamps for motor vehicles of categories M1–M3, N1–N3, L6–L7, and O, as well as vehicle installation requirements. Key provisions include definitions of front, rear, and side ADS Marker Lamp categories with specifications for luminous intensity, colour (blue-green), geometric visibility angles, and positioning. The regulation covers lamp approval procedures, technical requirements, conformity testing, markings, and vehicle-level installation specifications including electrical connections, operational conditions, and interactions with direction indicators. Transitional provisions and communication forms for approvals are included.
