Abstract

A lighting device is disclosed, which is provided for the front region of a motor vehicle, for example in a motor vehicle headlight, and which emits electromagnetic radiation during operation. The lighting device comprises at least one first primary radiation source which emits infrared radiation, and at least one second primary radiation source which emits visible light, wherein the first primary radiation source and the second primary radiation source are arranged in such a way that the second primary radiation source outshines the first primary radiation source and thus generates a color impression of the lighting device which deviates from the color impression stemming from the infrared radiation source alone.
