The document is an agenda for the 31st meeting of the GRE Taskforce on Autonomous Vehicle Signalling Requirements, scheduled for 18 June 2026 from 09:00 to 13:00 CEST via WebEx. The agenda includes welcome remarks, introduction of participants, adoption of the agenda (AVSR-31-01), approval of the report of the 29th meeting (AVSR-30-05), a report from GRE-94 / TF FADS (GRE-94-23), discussion of ADS marker lamps including Japanese input and a draft hybrid regulation proposal (AVSR-28-02, AVSR-30-03, AVSR-31-02/-03), miscellaneous items, working plan for future steps, and next meeting arrangements. Japan has offered to host a September meeting in Tokyo.

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.

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.
