I'm sure everone knows that on all Mustangs for the last couple body styles that the 3 tail lights on each side only illuminate together when the tail lights are on. When the brakes are on or the turn signal is on the inside light with the back up light doesn't function. Does any one know a simple way to make that light work the same as the others? I'm sure some one has done this. I think this would be a cool mod. I have seen the sequential stuff, but would rather do this.
