ABSTRACT:
A headlamp washing system wherein the liquid pressure source which supplies liquid to wet the headlamp surface also supplies liquid to actuate a linear motor which drives the wipers to remove the liquid and foreign matter from the headlamp surface. A flow restriction is disposed between the liquid pressure source and the dispensing nozzles adjacent the headlamp so that sufficient pressure and flow capacity are maintained by the liquid pressure source upstream of the restriction to operate the linear fluid motor which moves the wiper on the headlamp surface.
