Another thing...
Also included in the kit is the trailer plug relocation kit. It's not a big deal, but the screws included in the kit broke off on me when I went to install them. I ended up through bolting the relocation bracket with stainless machine screws.
With a normal (approx 6000lb capacity) draw bar from Reese or Draw-tite, you'll have to modify it to work. The instructions that come with the lights say to re-drill the hitch pin hole in the draw bar so that it will not interfere with the lights. On my installation, I would have had to move the hole back about 3/4 of an inch. The limit is no closer than 1" from the end of the bar. I didn't like this idea and have been looking for a solution. I found that the Reese weight distribution hitch draw bar is plenty long enough, and is rated at 10,000 lbs. You can mount a regular ball mount on it or a weight distribution set-up. It is a solid piece of steel, not hollow like the typical drawbars.
I really like these lights. They work really well.
Disclaimer: I haven't tried this personally yet, although it looks like it will fit with no problem.
