If soaring high electricity bills is your problem also, ad add to it your kids careless nature of leaving the lights switched on even when not in use, then here is something to help you. Check out this screw-in motion sensor switch. You just have to screw it in the bulb holder and then screw this sensor.
Once in place, this sensor will automatically switch off the lights when you leave a room for more than four minutes. Not just this, it will also detect a human approaching a room and switches on the light automatically. It has a range of 12 feet and 360 degrees. Sounds cool...seems a good option to save some bucks. Isn’t?

A motion detector used to turn on your porch light will save the most money. However, leave a small low watt bulb on all the time for safety if possible.
