The Jasu LED ice fishing light is your helper when you need maximum attention from predatory fish. The LED ice fishing light reacts to water and starts flashing, creating attraction in the dark water. The light is excellent for ice fishing in deep or dark waters. The light attracts fish from perch to salmonids. We recommend using the light especially with various spoons and flashers, as well as with vertical jigs. The light is attached easily and effortlessly to the lure with a quick-release clip. The battery lasts approx. 50 hours of ice fishing.
