I thought about putting a 3rd brakelight in the rear of the cab section just above the bed---the space looks like it was made for one. Sadly though, I am really pinched for leg room in the cab, and the back of my seat is probably going to be built right into the rear interior panel. Any 3rd brakelight frenched into that area would poke me in the back, and I hate the look of something hung on the outside of the body panel.
