“Although there is an overwhelming view that all-night lighting prevents crime, crime data do not show a strong relationship between lighting and crime rate.”

” Responsible illumination can enhance surveillance – which does have an impact on crime and safety. Light can have an impact on crime only if someone is likely to be watching. … too bright of a light may deter surveillance and actually aid criminal activity.

So, “security” lights do not replace human vigilance. “Security” lights can create a false sense of security, and poorly designed “security” lights can obscure criminal activity, both of which may ultimately be detrimental to a person’s safety.”

“Instead of dusk-to-dawn “security” lights, use motion-sensor activated lights. Motion sensor lights enhance surveillance by drawing attention to trespassers. This is the same logic as the car alarm or barking dog-the sensor turns lights on to call attention to a potential problem and to startle the intruder. Be sure to aim the sensor downward to guard only the area the lights illuminate.”
