My PBSF has spilled its guts on the road on two occasions. 1st time, bounced off the mount. 2nd time, U-lock knocked off the front of the light in mid-ride, base remained attached to the mount. On both occasions, I managed to collect the parts and the light still works, but the mount is not as reliable as I'd like it to be. Thanks for the links, it must have been a couple of years since I last checked out rear light options.
