These are a really neat set of lights. Unfortunately the sticky side does not stick very well to things. My boyfriend was very excited about these at first. He wanted to use them on his kayak, but he could not get the sticky side to stay stuck. So we ended up putting it on our head board and makes a great night light or what ever you want to use it for. We have noticed the lights have started to do their own thing though. It flashes constantly and then will shut off within a few seconds.
