jampot,<br> Please read http://www.equipped.org/pop_up_survivalist_def.htm. Most of the folks on this forum would be more concerned about using the torch / flashlight / signaling mirror to attract attention and therby rescue than suppressing all light thereby avoiding detection lest the maurading hords of post apocalyptic crazies. <br><br>Your suggestion about beta lights is right on. They are very useful, last about forever, and are very small. They don't give off much usable light except as a lure but they are great for fending off the fear and darkness for small children. I would definately recommend them as a replacement for Chemical light sticks in a kids psk as long as I also include a torch to keep them from breaking their legs when walking about in the dark.
