It's sad that fenix doesn't make a pocket clip for their other, non AAA cell based lights; I know there's a demand for them. The same clip from the above post can also be found on the new rayovac 1 watt sportman xtreme lights. You can probably also find them on the other
versions of that light that use the same body. There also the option that you can DIY one. While you can make one from scratch, you can also buy one from knife making supply stores as well as other places. The only negative of this is unless you find some other way to attach them; you'll have to drill and tap your holes.
Here's an example. I think most (me included) can agree that this is the most visually appealing way to do it. For my L2D-CE, I chose a different DIY route. After about a week of tinkering, I found something that worked for me and worked well I might add. The links in my signature.
