Abstract
The present invention is directed toward a lighting device in a motor vehicle that includes a first light conductor and at least one second light conductor. The first light conductor propagates light by total internal reflection which impacts on a light coupling-out area of light conductor and is at least partially reflected toward and emits from an opposite light output area. The at least one second light conductor propagates light by total internal reflection which is coupled into the first light conductor by a midway coupling-in. The light that emits out of the second light conductor via a light output area enters into the first light conductor via the light coupling-out area. An air gap is formed between the light coupling-out area of the first light conductor and the light output area of the second light conductor.
