ABSTRACT:
A vehicle side-view mirror water removal arrangement is easily retrofitted to vehicles having an existing source of compressed air and a side-view mirror with a reflective surface. The arrangement includes a valve having an input port connected to the existing source of compressed air and an output port, the valve being movable between open and closed positions to control the flow of compressed air from the existing source of compressed air to the output port of the valve. A conduit's proximal end is connected to the output port of the valve with its distal end located at the side-view mirror for conducting the compressed air from the output port of the valve to the side-view mirror. A fastener fastens the distal end of the conduit to the side-view mirror so that the compressed air flows down the reflective surface of the side-view mirror, a nozzle at the distal end being provided to spread the compressed air substantially over an entire width of the side-view mirror to clear any water adhering to the reflective surface of the mirror.
