I saw a advertisment in bass player magazine about installing a lighting system in your bass to make the inlay's glow so you can see your fretboard in low light situations. they call it "Sims Custom LEDs" It look's dam awesome, apparently you just send your neck to them and they wire it up for you and it only requires a 9 volt battery. I know the bass player from limp bizkit uses red one's, but you can get all differnt colours. I just want to know, do any of you use these? how much does it cost and what does everybody's thinks about this system? I've also attached a picture of one.
