ABSTRACT:
An automatic headlight cleaning system wherein a transparent cylinder encircles the headlamps and is selectively rotatable about an axis to be cleaned by a stationary wiper element positioned out of the light path. The transparent cylinder is closed at one end by an integral end wall, and the other end is closed by a separate wall element fixed to the housing within which all the elements are mounted. The headlamp wiring extends through the fixed end wall, and an O-ring seals the annular space between the fixed end wall and the transparent cylinder. Means are provided for applying a cleansing liquid to the external surface of the cylinder by a forced spray and a rotating brush scrubs the external surface of the cylinder in advance of the wiper element. Drive means are provided for selectively rotating the cylinder and brush to position a clean section of the cylinder in the path of the beam.
