A snow removal apparatus adapted to be mounted on a vehicle, for removing snow from a light fixture protruding from the ground. Structure is provided for creating a flowing stream of air and a nozzle connected to the air stream directs the air stream at the ground, the directed stream of air having a flow velocity of at least about 180 m.p.h. The nozzle is adapted to be operatively positioned adjacent the ground at an angle to deflect the directed air stream on the ground at a predetermined distance from the light fixture so as to cause the deflected air stream to impinge on the light fixture at a reduced velocity sufficient to remove snow therefrom without damaging same, and to spread over a surrounding area with sufficient pressure to clear the area of snow.
