I would like to present an idea of mine: Crocs headlights which are actually useful when going out at night. I had bicycle lights laying around and thought of making a mount to put them on my crocs. It looks pretty cool, as well as people can see me in the dark. Also, I can see in front of me in dark places. I am loving it! Let me know what do you think of the design. It is custom fit to the lights I had but it should be pretty standard light. 

Also works with bagpack lights.
