Fenix tailcap disassemble

Inside the tailcap around the spring you can see a metallic ring with two tiny holes in it. With the help of needle nosed pliers, scissors or even a couple of nails you have to unscrew this ring. The switch and the rubber boot will come out from the inside.
May I suggest that before replacing the boot you put a small amount of silicone grease on its lip so to improve its water tightness. :)
