Abstract

An illuminating device for motor vehicles has a plurality of light sources formed as semiconductor light sources, each of the semiconductor light sources emitting light of only one color and light colors emitted by different semiconductor light sources are different. The semiconductor light sources include several semiconductor light sources which emit light of a same color. The semiconductor light sources are distributed so that the lights emitted by all semiconductor light sources produce a light of a uniform color which exits the illuminating device.
