ABSTRACT:
A wiping system for cleaning snow accumulating on the rear signalling lights of a vehicle, using intermittent blasts of air. The blast wiping system comprises timers and a solenoid valve for regulating a flow of air from the air reservoir of the vehicle into intermittent gushes of air. The wiping system comprises also supply tubing for connecting the solenoid valve to the air reservoir of the vehicle, nozzles for directing the intermittent gushes of air toward a surface of the vehicle's lights, and delivery tubing for connecting the solenoid valve to the nozzles. Each nozzle of the blast wiping system is placed near a lower quadrant of the light surface. Each nozzle is further oriented to deflect a gush of air in a tangential upward direction relative to the surface of the light, whereby a layer of snow on that surface is lifted off and blown away in a patch-like formation. The components of the blast wiping system are pre-wired and pre-tubed such that an installation thereof on a vehicle by a person unexperienced with pneumatic does not compromise the safety purpose of the compressed air system of the vehicle.
