Here's another example to a roof rack. 30" on a SD rack and I wanted it to mount between the contours of the rack lines. I had to make some flat brackets but you'll have to decide how you want to mount it.

 

Got mine mounted, it's not fancy but for the money it gets the job done. In hindsight I probably should have either gotten the spot or combo pattern rather than flood but. It works to light up the area right in front of the truck that the Hella's and headlights miss.
