I got some $20 driving lights from walmart. They are very bright and I just upgraded them to 100watt bulbs so they are even brighter now.
Best picture I have showing them.
You just have to be careful if you go down a seep incline wile off roading, that is if you do. I just broke the lens on both of them a couple days ago because I smacked them on the ground. If you have a hitch and mount them the same way then you will be fine though.
