Abstract: A lighting device for a motor vehicle has a laser light source from the light of which light radiation is generated into the area around the motor vehicle during operation of the lighting device. In the lighting device, a plurality of optical channels is associated with the laser light source, and the light of the laser light source can be guided via each optical channel in order to generate a separate light spread associated with the optical channel from the guided light in the area around the motor vehicle. An optical element, which can be switched by a control device into different switching states, is provided between the laser light source and the plurality of optical channels. A different switching state is associated with each optical channel. In each respective switching state, light from the laser light source is fed only into the optical channel with which the respective switching state is associated, by means of the optical element.
