Doug, any issues with the combo above? I have the 13060 flashlight along with this 15642 mount. The mount doesn't fit the light perfectly.

I made it work by strapping a rubber band onto the flashlight. Another annoying issue with the mount is the fact that I have to unscrew the tailcap to get the light onto & off the mount.

That may not be a problem if you leave your light on the bike 24/7. I lock up my bike on a daily basis and need to remove the flashlight on a daily basis.....it gets tiring.
