That is a cool first mod! Those mounts are made my Rigid Industries. As far as I know they are the only ones who sell a dual mount like that. You should be able to put any Square LED Lights on that mount that you like, so let me know if you'd like a quote on a set!
Unfortunately I don't carry Rigid so I can't get the brackets for you, but I do have a few different lights that will fit on them as well as the wiring harness. Let me know if you'd like a quote on the lights and harness!Thanks Ryan, I'd like a quote for the brackets, LEDs and all the wiring I'll need.
