When we used to carcamp, we found a couple of those solar powered lights worked well to give a little light in the camp. They are a good beacon back to the camp for those who get disoriented in the dark.

One thing fun to do is take a picture in the dark while each kid traces a letter of a name. If you do it quickly, you can get a picture of the name in lights.

Here is a good sample: http://www.facebook.com/photo.php?fbid=1...elevant_count=1
