Status report on the development of a Hybrid Regulation on ADS Marker Lamps. The task force has largely completed the document, which specifies lighting performance and installation requirements for ADS Marker Lamps on motor vehicles of categories M, N, O, L6 and L7, and includes both component and vehicle approval procedures. The report identifies items requiring GRE guidance on marking legibility, lamp placement and dimensions, geometric visibility angles, substitution of required light-signalling functions, and electrical switching conditions for ADS Marker Lamps.
