Pimp My Ride
Imo this one is one of my favorite LED mod along with member Particlewave's interior/dash LED retrofit. These guys would be able to advise you on the tapping thing.
Would below, the location of the LEDs, be a sufficient light output to fill the footwell? I think this is a great mod... added safety included, nobody is going to run over him when hew gets out of his car. brilliant!
