FWIW, I've just installed a pair of auxilliary backup lights. Advance Auto has sets of Optronics QH-101T off-road/racing lights for $20. For that price, I figured I couldn't go wrong. I also bought a standard small relay typically found in the PDC under the hood.
Mounting was fairly easy. I drilled out a hole in the mounting brackets to fit the Torx bolt under the bumper and mounted the lights under the bumper just on either side of the registration tag and aimed them slightly outward and horizontal.
Wiring was also fairly easy. I zip-tied the relay to the trailer harness at the hitch mount near the plug. I tapped into the B+ to feed power through the supplied fuse to the relay. I tapped into the backup light wire to control the relay. Ran a wire from the other side of the relay secondary to the ground from the lights, and tied it to a suitable ground. Then I connected power for the lights to the normally-off terminal of the relay's primary circuit.
Finally, I wrapped most of the wiring in electrical tape and zip-tied the wiring from one light to the other up onto the bumper; there are some convenient holes there to hold the ties.
Et voila! I now have *very* bright (110W) backup lights. They only come on when I shift into reverse. I should be able to see back there in the worst weather now, the OEM backup lights, as y'all well know, are next to worthless. But DC aren't the only ones; Dad was just complaining the backup lights on his Town Car are quite abysmal as well.
As I said, for $20, I couldn't go wrong.
