A couple of years ago I saw a fellow who had put 2 circular LED lights in the bed roll holes and run the connecting wires through the tubes and back out of sight. I thought it was pretty slick. At eye level for cars and pedestrians can see it easier than some of the ones I've seen people mount on or under the bumper and it doesn't look weird or get in the way of the tailgate. I even considered making these for the AD trucks.
