I have two white cold cathodes that piggyback into an inverter.. I was going to use them inside of an amp rack/box project for my car but it never came about so now I'm trying to figure out what to do with them now. Hm, in fact maybe I can salvage that idea or something, since I actually made the box out of MDF and all that needs to be done is carpet it, mount the fans, and such.. Dunno.. Anyways, they ended up costing me about 25 bucks shipped. My problem was I was going to fuse them but I can't find a fuse small enough.
