Rigid industries SRM kit.
I put them on the tow bar there were 2 holes already there. It was meant to be. The reason I got then was for backing up in the dark roads and camping.
I didn't flush mount - I want to retain ability to aim!
I used the switch provided it's great. You can wire it so it is ON-OFF-AUTO (comes on with back up lights)
Which is really great feature.
You can probably piece together something for cheaper but I wanted the kit.
