This standard specifies the requirements for measurement of electrical, photometric, colorimetric and retroreflective properties of road illumination devices, light-signalling devices and retroreflective devices for road vehicles including their light sources as given by various UN regulations. These properties are usually acquired with a DC supply voltage, possibly supplied by an associated light source control gear.
