My Lincoln has a switch for the interior lights, so I didn't need one for inside the car. For the outside I wired in a switch for the power that ran the BOO (Brake/On/Off) switch behind my brake pedal.
The Snyper
Before going with something similar to those BBS type wheels, consider that those are a PITA to clean wheel. You have to take your time if you want it to look decent, not half a donkey's butt. That's where the 5 spoke design is handy.
Just my 2 cents. :)
