I currently have this Trek brand LED blinkie that has steady and flash.
When I first got, it had a rear clip for sticking to anything(yeah, right) and a standard seat-post clamp.
Since I have a bag on top of the rack, there was almost no use for the seat-post clamp.
The post-clamp nearly worked by keeping it attached to my U-Lock, and securing the U-lock under the bag. But the God awful ruts around here snapped the clamp bracket in two.
Next thing I did was jury-rig the mounting bracket clip onto the existing reflector holder.
This held the light until I accidentally snapped the light clip during battery change.
Now it stays on due to a nut/bolt/washer combination that involved drilling the boltscrew through the back of the light. This works for now, but the bolt screw shoves the AAA battery out a few millimeters.
And battery changing is pain in the a$$.
So, does anyone know of any rear LED lights that are rear-rack reflector mounting bracket specific?
Because I don't really feel like having to bust out the magic bag after buying another light.
