Light Switch Motion Sensors

If you are tired of hounding the energy pig in your household, aka husband in my house, light switch motion sensors are the stealthy way to go. My husband will leave all lights on in all rooms he intends to visit or revisit during the evening. I am baffled as to what ails him that it appears too much trouble to turn the light off when he leaves the room. And however much I moan and complain, he obstinately continues with his oinkish habits. Only a $450 electric bill in our summer home where he lives full time had him sit up and start to pay attention. But a lifetime of bad habits are hard to change and when I am not around I know he will continue to do what he pleases- and I end up paying huge electricity bills. Can you tell I am annoyed? So my next project is to put in light switch motion sensors one day when he is out of the house, on the lights he leaves on most. That way we do not have to have argument about it. The lights will just go off whether he likes it or not. I will let you know how it goes.
