Abstract
Abstract A lamp arrangement for a motor vehicle comprises a light source including a plurality of bulbs and arranged in a rear shelf panel, and a transmission hologram mounted on a rear window on the cabin side thereof. The transmission hologram includes a plurality of divisions which have different diffraction characteristics from each other. Almost all incident lights from the light source are diffracted by any of the divisions rearward of the vehicle.
