Two 18W lights (36W total) only consumes 3A. Wouldn't need a very big relay (or one at all, perhaps). If you swapped out the backup-lights with LEDs I'd bet the total current for the all-LED setup would be less than the original incandescent backup lights!

you know, I hadn't slowed down long enough to do that math.... and think about it.... but that is very helpful! at 3 Amps, added to the roughly 4.2 A or so from the existing incandescent.... it's still not a very big load at 7 to 8 amps. It's approx 15 Amp circuit as best I can tell searching on google.
So I'm thinking I'll be fine to just tap into the tail lights.... unless it's some sort of computer controlled circuit that is very sensitive for some odd reason.... right?
