Church Tackle Bead Chain Spotlights
I like using Church Tackle's Bead Chain Spotlight. They are small LED lights that you put right above your lure or bait and man do the crappie love them. I like them because they only cost around $7 each and I can get replacement batteires too. I think having the light where you want the fish to bite makes all the difference. I haven't seen them in stores yet, but here is the link to their website if you want to check them out. Church Tackle - Planer Boards, Fishing Tackle, Lures, Trolling Equipment, & Accessories
