Outdoor lighting timers are small appliances that you can program to turn your home's exterior lights on and off at specified times. Using an outdoor lighting timer can save both money and energy since you never have to worry about remembering to turn your lights off. These timers can also help to deter thieves by making it look like you're home when you're away. If your outdoor timer malfunctions, you can reset it to factory settings and reprogram it in just minutes.
Locate the "Reset," "Restart" or "R" button on your timer. Press and release the button to clear the timer's programming and return it to factory settings.
