Running the wire to the lights would be the easiest. Personally I'd run wiring and put them on a switch in the interior. If you have you a buddy run the wiring through the firewall, it's pretty easy. I bring up an interior switch since that I am not sure if it's illegal for you to run off road lights on the road. With that big of a light, that's going to be a lot of light. Give us an update when you can.
