Abstract
Abstract A device for cleaning a lamp arrangement of a motor vehicle such as, for example, a divided headlight arrangement which is disposed so as to be set back with respect to a forward panel frame member of the motor vehicle. A separating web of the panel frame is located between two juxtaposed lamps of the divided headlamp arrangement with at least one nozzle being disposed in two lateral surfaces of the separating web. The nozzle is oriented toward the respective lens of the headlamps and emits a jet of cleaning fluid on the respective lenses.
