Good invention for night walking or night sports!
I had a bit of trouble putting one of these together, even following instructions carefully.  I had it set up correctly but the light would turn on but not remain on.  It kept flickering right back out.<br /><br />I am not certain what was wrong, but I took it apart and put it back together twice and on the third try, it now is functioning FINE!  The other light went together and worked properly without any fuss.<br /><br />These lights are like little headlamps for your feet.  They clip onto your laces and you can point them down and away from you so they illuminate the path in front of you.  This is brilliant.<br /><br />I have a crutch and I walk a dog, so holding a flashlight, a leash, and a crutch was impossible for me!  Now I do not need to use my hands to have a safe walk at night.  What a help they are!<br /><br />If I have any more insight as to what went wrong with the troublesome light, I will update it here.  If you dont see an update, it resolved on its own.<br /><br />Nice, too— they send another extra set of batteries in the package.  thoughtful!<br /><br />UPDATE:  I use these EVERY night.  These work wonderfully well.  I have NO more trouble with the switch.  So many people have stopped me to ask me about these as I am walking along in the dark neighborhood.
