Brian, hes not talking about black lights. he is talking about the little led lights you put on your deck or in your compartments. I added them to my livewells and most of my compartments and to my trolling motor foot pedal tray. the ones in the livewell are the greatest invention ever. really helps you to see the fish when you go to get them out, especially for night tournaments. i use the ones in my foot pedal tray for retying at night. nice lights and they are cheap and easy to install. and that guy that owns them is a super nice guy.
now on another note, as brian was talking about, I still have the sloan blacklights setup. i just cant get rid of them. especially since they have the white light to retie and the blacklight. dad got some of the led blacklights and i can see his boat from a long way away, so it has to be easier to see your line. The thing i hate is the dam plugs corrode after about a year and a half, even with a cut off switch on them. its a poor design with no where for the water to run. but i found a guy on BBC that sells them for like $25 a set (better than $40 or $50 a set).
