An apparatus for attracting fish includes a light source for emitting a green light. The light source is disposed within an enclosure which is removably attached to a rigid structure at a predetermined distance above a water surface and includes a diffuser capable of passing the emitted light therethrough. The light source is electrically connected to a power source capable of supplying 120 volts AC. Control switch disposed intermediate the light source and the power source selectively controls supply and termination of the voltage to the light source. The emitted light penetrates the diffuser and the water surface and is transmitted to a predetermined distance below the surface of water.
