I am surprised that I have to give this rating, but! the clip failed its purpose and myb rear cateye light and clip fell off my saddlebag 8 miles into it's first trial on the bike when we hit a section of rough tarmac. This surprised me as the clip looked secure enough and even has an extra lip on the end to help prevent this from happening. Clip was positioned properly on the saddle bag strap that is designed for this type of positioning.
By pure luck, the cars behind me didn't run over the light.
