It seems like a no-brainer to leave the lights on outside your home to deter burglars while you’re away. But does that really work, or is it just a waste of electricity?

When to Keep Your Lights On

• When you’re home (and awake): It allows you to see anyone approaching.
• When you go out at night: Facilitates safer entry to your home.
• Combine lighting: Use a mix of porch, garage, and interior lights to simulate activity.

When to Keep Your Lights Off

• During daylight: A light left on all day is a sign of an empty house.
• While on vacation: Consistent lights for days signal vacancy.
• When sleeping: Most residential crime occurs during the day.

An Even Better Option: Automate

Automate your lighting to turn on/off at varying times. Motion-sensing lights are also an affordable, effective deterrent.
