It can get stuck on there pretty good. Give it a good soaking overnight with some penetrating oil and then use some rubber gloves and turn counterclockwise. The second ring behind the bezel will have three notches in it so you can use a couple punches to turn it out. When you get ready to put it all back together use some anti seize on the threads. Lube the two orings also. Both the bezel and the retaining ring have orings on their backsides. When you replace the two little lock screws in the bottom use loctite as they will vibrate out and you will loose your bezel as many here have.Trying to change the headlight on my Bulldog. Removed 2 set screws on the bottom. I think the bezel is supposed to screw out but it won't budge. Any ideas?
