Larry: I bought them at west marine, theres a left hand and right hand version and they fit in the holes on the bracket. since the warm salt water of te gulf plays havoc with the wiring, I bought a wiring harness and re-wired the trailer also. LED's require a good ground so Iran a separate ground wire to both light assemblies. I soldered the joints and covered them with liquid rubber to help cur down on the corrosion. Sorry, no pictures right now. Don Ludlow M15 #620
