These underwater lights are used to attach to your line, to attract fish or squid to your lures, they work really well! Use them for squid fishing at night - hook a snap swivel to the acrylic ring at the top of the light, and attach your squid jig up about 12" from the light, and usually use three jigs about 12" apart. The same setup will work using Sabiki Jigs, just hook your light to the bottom of your Sabiki Rig, and you're in business. The light shines up on them from below, and the up and down jigging motion puts your bait right in front of the squid or other targeted prey. Makes the squid go crazy for them. You can also use these lights for deep sea fishing, such as for Halibut. Put one of these lights down by your bait to help attract fish to your bait. Remember, you get down past about 100 feet deep, and it starts to get dark down there. Improve your fishing success by using light. These are a LOT easier that bringing a generator, or battery pack to power your light! A lot cheaper than chemical lights too, especially if you use rechargeable batteries.
