Abstract
The lighting device has a central reflector (10), in which a first light source (11) is located in the operating position. A light guide (11) extends from the light source in the operating position and conducts light issuing directly from the light source and reflected light from the reflector (10) to vehicle light units. The first light source (11) is located in a supporting member (21) on which an additional second light source (22) is mounted. The supporting member (21) is movable relative to the reflector (10), so that on failure of the first light source located in the operating position the second light source (22) is moved in the operating position by a shifting device (26). The shifting device can have a control unit (36) and a sensor (37) connected to the control unit (36), which detects light issuing from the light source (11) in the operating position. On failure of the light source (11) the shifting device (26) is activated by the control unit (36).
