None taken. It is a different kind of light. Cathodes are cheaper, brighter, and use less power than neon...I don't know about LED though, they should be low draw as well.

Next...when I get to it, will be the floor of the back seat. I just don't know how to do it to light up the whole floor, but not have exposed tubes. Maybe someone can point me in the right direction

you can mount the rear cathodes or whatever under the rear seats. Just make a bracket that bolts on underneath the seat on the frame that holds the tube right where the floor meets the seat bottom. you cant see it there unless you open the front door and crouch down looking for it. i have long led boards that im gonna put inside a plastic tube and mount it that way. lights up the rear just fine.

Sweet, I'll have to check it out.
