Abstract
A headlamp cleaning system has a headlamp especially suited to HID or tungsten halogen applications including a source of light and a polycarbonate lens for distributing the light and a control system for automatically controlling a pump for distributing washer fluid against the lens each time that the vehicle ignition is turned on and whenever a sensor for sensing dirt build-up on the lens signals the presence of dirt build-up thereon and the control system continues the cleaning cycle until all dirt is removed from the lens.
