An Easy Advantage for Fisherman


These underwater lights are proven to attract fish at night, or low light conditions. They attract baitfish to the surface, which ultimately attracts the larger fish beneath. Add a pair of these lights, some fresh bait, and a few good fishing rods and you'll definitely be in for an eventful night. They're pretty easy to install and the bulb can be changed without having to take the boat out of the water. They don't heat up because of the grooved outer flange. The only downside to these lights is that they aren't as bright as some LED underwater lights and draw more power. They also look great at the dock, mooring, or anchor and provide great ambiance to any boat.
