It sure looks nice. Can you please explain a little bit on how to build one? Driver and LED. Safety orange would look good in that light.
Its a low volt p60 drop in with the spring cut off. The tail cap has a forward clicky in it, cant remember which one right now, but I also cut most of the spring off it. I filed the tail cap by hand and the head was done with a Dremel and file. I hope that helps.
