I just got my first "high-end" flashlight today. It's a surefire A2. Unfortunately, it's not working right. It didn't do this at first, but now the LED's fade in and out. The incandescent has worked fine thus far. The LED's will suddenly turn off, but sometimes if I wiggle the tailcap they come back on. They flicker, too. I think something in the tailcap is not connecting the way it should. How can I disassemble it to try to fix it? I have to go, but I will post more info later.
