About 2 years ago, I bought the cheapest plastic rectangular fog lights from Harbor Freight for about $8.00 a set. Ran a heavy wire from the battery back to the rear jack compartment, then installed the relay that is triggered by the reverse lights. Held the lights (after cutting hem up to make them fit) in place with black silicone sealer and aimed them when the sealer was about 75% set.
Haven't fallen out yet and works great!
