I am a big fan of using those solar walkway lights. I bought 2 of them for $3.87 each at Home Depot and they lasted 3 years. I now need to replace them. they may have lasted longer if I had actually bother to mount them to something. All I do is take off the stake that you would normally use to push it into the ground by your sidewalk and then I set them in the windows of my coup, one at each end. They give off just enough light to coax the girls in when it starts getting dark and it also allows enough light to do a head count in the dark when I close up the coup. If you do this make sure you do something so they stay in place. Somehow my girls managed to knock them out of the windows and then they get lost in the deep litter.
