Abstract: An air blast wiper system and method for removing snow from a vehicular marker light includes an automatic control system connected to an air reservoir for regulating a flow of air into predetermined intermittent gushes of air. Supply tubing distributes air from the automatic control to a predetermined location on the vehicle. A uniquely oriented truncated conical nozzle is used for directing the intermittent gushes of air from the supply tubing toward a surface of the warning light in order to maintain the warning light in a visible state when the vehicle is driving in a snowy or icy conditions. The automatic control includes a pressure switch for determining if the pressure in the air reservoir is below a predetermined level and for preventing use of the blast wiper system to enable the vehicle's air braking system to remain operative.
