Screw the bracket - clip it onto your bag. Mine clips on a loop of fabric that attaches one of the buckles to the rest of the bag. The light's not going anywhere and I can turn it on / off while I'm riding easily.

On the topic of checking peoples' bikes out ... ya, I do that all the time. I'm a dirty perv when it comes to leering at hot bikes on the street.
