ISO 4148:2004 specifies the dimensions of special warning lamps for road vehicles, in order to ensure interchangeability and accurate positioning, bearing in mind the rapid change of light intensity from such devices in a vertical cross-section of the projected beam. It also specifies methods for testing magnetic-base-mountings used to install special warning lamps directly on the steel sheet of the roof or body of a vehicle.
