best setup for led backup lights

Anybody have a good idea for mounting backup lights on backrack? I've been mounting under rear bumper in the past but they get destroyed by snow banks. Wondering if there will be enough illumination from the rack
I mounted one on my hitch bar under the bumper. (sierra) then put another on the rear topp of my truck bed aimed it down. Those lights are great!
