Abstract
Abstract A system for enabling remote controlled cleaning of the headlamps on a vehicle such as an automobile wherein compressed air is utilized both to project a cleaning fluid onto the headlamp and to blow the cleaning fluid off the headlamp for drying purposes. The system includes circular discharge nozzles which are disposed slightly forwardly of the headlamps and have a plurality of discharge orifices directed toward various portions of the headlamp surface. The cleaning fluid includes abrasive particles suspended therein to loosen and remove foreign material on the headlamp surface.
