if you are installing the lights under the dash and seats, then yes, cold cathodes would be your answer. they are very easy to install. all you need is a 12v source, and then ground. i have an Add-A-Circuit in my fuse box which is powering all of my lights. then i just grounded the wires all to a screw on the fuse box. i would be happy to help you if you ever need it..ya, the only thing is i've read that the oznium stuff is actually sumtiems a little bit TOO bright =p hahaha. i've got a friend with neons in and it looks pretty nice. idk, im debating. if i were to get some from oznium, would i just want the cold cathodes? and how hard wuld that b to install? (sry, not trying to threadjack, just dont wanna start a whole new one)
