It seems to be a pretty time-honored advertising strategy that when you want your message to really hit, you need to connect it to things men want/don't want to happen to their penises. In this example, found on Tumblr, wasting energy is … blue balls, or maybe priapism? And turning off the light is an orgasm? In any event, if your light is on for more than four hours, consult a physician.
