This International Standard defines the essential character-istics for the installation of lighting and light signalling devices on motor vehicles1' and their trailers intended for use on the road with the exception of vehicles which run on rails, agricultural or forestry tractors and machinery, and public works vehicles.
Attention is drawn to the fact that some of these requirements may be modified or up-dated to take account of technical and regulatory2' development.
