I have gotten the bezels off quite easily, not only on my Novatacs but also on my EX10's. Remove the front end of the light from the battery compartment. (For some reason, I haven't figured out whey this step is extremely important.). Press the bezel into a rubber soled tennis shoe (I actually use a shoe from Payless that claims it has oil slip resistant soles). As you press inward firmly, unscrew. It really doesn't take much effort. I have talked to Novatac, and that's how they do it when they have to service a light.
