A spraying apparatus includes a nozzle connected to a pressurized liquid supply and dispensing a spray pattern from a discharge orifice of the nozzle A stroboscopic light source is mounted on one side of the nozzle and directs a pulsating light beam along the spray pattern such that the spray pattern is stroboscopically illuminated and visible to an operator on the opposite side of the nozzle. Continuous light can also be provided to illuminate the spraying apparatus for night operations.
