The underwater lighted fishing lure utilizes a two-color lighted system (blue, green, blue-green, white) which either blinks two LEDs ON and OFF (cyclically or randomly) or includes laterally extending fins causing the underwater lighted fishing lure to spin or rotate due to current flows thereby flashing colors from a certain perspective underwater. Light emitting devices (LEDs) maybe driven with excess voltage or current (above 3.5 volts) by 2, 3 or 4 lithium batteries or 3 or 4 alkaline batteries. To modify the beam of light from the LEDs, light modifiers, light diffraction gratings and light reflection surfaces disperse the light laterally away from the elongated housing. Chemical lights of different colors with laterally extending fins are spaced apart to facilitate breakage and activation of chemical capsules. A clip system with a double spring action includes a U-shaped clip at an end of an O-shaped body.

The underwater lighted fishing lure includes, in one embodiment, a transparent housing, two or more batteries and two LEDs of different color. Studies have shown that the use of two color LEDs in a single lure greatly enhances fish catch. Another embodiment drives the LEDs with a voltage at or above 3.3 volts. An additional embodiment uses lithium batteries. A further embodiment drives the LEDs at or above 150% the recommended voltage or current. Studies have shown that driving LEDs at higher voltages significantly increases fish catch. Additional features include a blinking circuit for the two color LEDs and a planar wing to either the battery powered fishing lure or a chemical luminescent fishing lure which causes the lure to turn based upon underwater flows and currents. This turning simulates a color ON and OFF cyclic operation.
