Basically, you flip the brackets on the light to where they're upside down and where the bolt sticks straight out the back. Then, you drill out the hole in the bumper (plastic, very easy) and bolt the light on. It's pretty easy.
Mine face down a little more than I'd like, so I may "modify" the bracket a little to where it will be more perpendicular. It's a few degrees off right now.
The light itself fits just fine.
