Hello everyone! I've lurked around this sight recently and decided to pick up a Surefire 6p incan with the expectation of eventually getting a p60 LED drop-in. I just received the light a few days ago and tested it out - I loved it! However, later that evening I pressed the momentary-on to check on what the cat was getting into - the light turned on for a flash, but then shut off and now won't light. I checked the bulb - the filament appears to be fine. The twisty tailcap still seems to feel like it did before, but both the momentary on and constant on won't work. Any ideas as to what the problem might be? I'd hate to have to send my light to Surefire after the first day!
