Very nice, robust mount, with a few caveats. Could it be a little wider to be able to mount two bolts to it, at least on my rack. Luckily it has the center hole which I used and seems to be fine. Also, would be kind of nice since it goes on a license plate mount, under a rear rack, that the light would mount in the opposite direction, so the switches would be on the bottom and be less prone to possible rain intrusion, or intrusion from washing the bike. Other than that a very nice product as well as the Vmax light. Went for a daylight ride with my wife the other day for about 20 miles, and son or shade I had no problems seeing her at all, so I'm sure any Vehicles approaching us are very aware that we are there. Great job!
