FYI: This is possibly the worst location you can mount a radar detector. You will get limited off axis detection (especially to the right where most cops sit) and zero rear detection since it points right into you. The ideal location is in the center and high up and as horizontal as possible.

Unfortunately, the map lights aren't a bulb, it's an actual diode. I imagine you could solder in a different color diode, but it's definitely not plug and play.
