Use LED fog lights and wire them to the running lights via a switch and fuse. Your running lights will be (afterall, it's dark, right?) then just go out back, look at the supposed path, SWITCH ON THE LIGHTS, and Ba-Baam! you have great backup lights. You could also put a couple more on the sides of your rig so you can see where SP (Special Person) is so you don't run S/Him over (but then, maybe it would be a good excuse).
