The roof lights I would only be using offroad. The lights I want to mount on the bumper I would use on the highway when I need more light, thats why I wouldn't want hids because you're always turning on and off your high beams for on coming traffic.
Thats what I'm thinking. They come with 55w bulbs so I will see about replacing them with 100w, still not sure on the hid kit. Going to see if I can do a test fit tomorrow on the 500's. Also looking at the hella ff75's for rear lights to blind people when the ride your ass....I mean to see better when backing up.
