Energy Saving Coin Operated Light Switch..... What an interesting concept!! (These would be particularly helpful in kids bedrooms on timers-- it will help teach them to conserve energy, save and spend money wisely, and the light can be timed out on its own.... No sleeping with the lights on all night)
