USE MOTION SENSORS TO SAVE MONEY: Lights will come on only when they are in use and you'll save time and money. Also, use outside to light up your yard when someone walks towards the house.
USE TIMERS TO SAVE ENERGY: Use them in garages, closets, attics, basements, and to ensure the light is never left on longer than needed!
Test smoke detectors at each daylight savings time! At that time of year, change the batteries and check the volume to make sure it is loud enough. If your smoke detector is close to 10 years old, consider replacing it soon!
