The Surefire Pocket Clip is designed as a simple way to add a functional,
durable pocket clip to your one-inch body Surefire flashlight. Just remove the tailcap, batteries and o-ring seal from your light and carefully slip the pocket clip down over the threads. Then re-assemble your light and you're ready to carry. Each clip comes with a handy finger ring, or you can use any lanyard you'd like on the built in lanyard loop.
