Exterior lights are important, especially near doors and in the rear of the house, where intruders do most of their work. All sides of your home should be protected by security lighting that is located high out of reach, and is vandal resistant.

Lighting in carports and garages is critical. For garages, an automatic garage opener is the best choice. Almost every garage door opener made today has a light that comes on when the opener is activated, lighting the garage interior. In carports, it is best to either leave a light on, have a light on a timer, or have a light connected to a motion sensor or photoelectric cell.

The best light to use on the exterior is a motion detector. The advantage to this type of light, especially in the backyard, is that the light warns the resident that someone is in their yard. While there is a concern that dogs, cats, or birds will trigger the sensor and cause the lights to come on, if the resident sets the sensitivity of the sensor correctly this will not be a problem. In the front yard, any type of lighting will be effective, as long the lighting pattern covers the entire front and sides of the house. Sensor lighting will be effective, but is more prone to "false alarms" caused by things like people walking down the sidewalk, or children playing.
