Has anyone done this for a reverse light? Is it doable ?
Use a relay and splice into the reverse over-ride wire .

I realize it will come on when not needed sooo ..
another option would be to run off a 3-way switch .
switch up = light on
switch off = light off
switch down =light works whenever you hit the R/O switch.]

I by no means am a 12v guy but have been thinking of this ,,,,Is it possible,,,Does anyone see a problem with it?
