Outdoor lighting has the potential to deter burglars and reduce crime against your home and property. The key is providing enough light so you can see and identify people who approach your home at night or your neighbors and passersby can see them.
It is a combination of light and an increased chance of the criminal being seen that must work together. You can create an extra layer of security through a connection between lights that are permanently on, the use of timers and motion activated lights.
