Abstract: A cleaning device has a tank for liquid and a conveying device as well as an outlet opening. A conduit is connected to the tank and to the outlet opening. The conveying device is connected to the conduit and introduces a compressed gas into the conduit so that the cleaning medium exiting from outlet opening is a mixture of the liquid contained in the tank and the compressed gas.

Abstract: A light assembly for a motor vehicle has at least one light source connected to a circuit, wherein the at least one light source has a light output that is adjustable according to external light conditions in order to prevent blinding of the driver in a following vehicle and in order to ensure proper light intensity during daytime operation.

Abstract: A taillight fixture for a motor vehicle has at least one light window and a light arrangement with lights, including a brake light, a turn signal light, and a taillight, arranged behind the light window. Light beams emitted by the light arrangement pass through the light window to the exterior. At least one first light-sensitive sensor is positioned in the area of the light window. A control device is provided and the at least one first sensor is connected thereto. At least one of the lights of the light arrangement is connected to the control device, and the control device controls the luminocity of at least one light based on signals received from the first sensor.

Abstract: A circuit for protecting electrically operated lighting elements used for illumination or signaling has at least one PTC resistor connected serially upstream of the lighting element. In another embodiment, the circuit has a self-regulating current supply connected serially upstream of the lighting element. In yet another embodiment, the circuit has a down convertor connected serially upstream of the lighting element.
