Abstract
The invention provides a car lighting unit comprising a reflector and a light source arranged to generate light. The reflector circumferentially surrounds the light source and has a reflector opening. The reflector is arranged to reflect at least part of the light from the light source through the reflector opening. The car lighting unit further comprises a source-related 3D hologram and a source-unrelated 3D hologram. The car lighting unit is 5 constructed to generate a beam of light and a source-related holographic 3D image, using light from the light source, during operation of the lighting unit, and a source-unrelated 3D holographic image when the lighting unit is not in operation.
