Burglars won't find your home an "easy mark" if they are forced to work in the light. In addition to being a deterrent, good lighting also allows you to see if a threat or suspicious person is lurking in your path. If you are able to see a potential threat, you at least have the choice and chance to avoid it. 

• Force any would-be burglar to confront their real enemy—light. Exterior lights and motion detectors, mounted out of easy reach, can reduce the darkness a burglar finds comforting. 
• Illuminate or eliminate places an intruder might hide: the spaces between trees or shrubbery, stairwells, alleys, hallways, and entryways. 
• Make sure there are no shadows or dark areas around the house, garage, or yard in which a person could hide. 
• Set timers on lights when you’re away from home (or your business is closed) so it appears to be occupied. 
• Don't depend on streetlights or lights from adjoining properties. 
• Leave outside lights on after dark. 
• Check lights regularly and replace burnt out bulbs. 
• Protect your lights from vandals with wire covers. 
• Padlock your circuit breaker box to prevent lights from being turned off. 
• Exterior lighting should be bright enough for you to see 100-feet. 
• Be sure your lights don't shine into the eyes of passing motorists. 
• Remember that leaving your garage or porch lights turned on all day is a dead giveaway that you are out of town.
