Hackyrat, if you go toa truck store that sells items for semis, they should have what you need. i got 2 round led's, pigtails, rubber gromets, and brackets to mount the leds. just drilled holes in the old mounts on my trailer, bolted the brackets up, wired the lights up and was done. the pigtails seal real well to the leds, with rubber seals, and you could some die electric grease to help. they also have many different stlyles of leds.
