CRIME AND SAFETY WITH DARK SKY
Dark sky principles improve safety by reducing glare and increasing visibility, challenging the myth that "brighter is safer." They also preserve natural darkness, benefiting human health, wildlife, and astronomy. This is accomplished by using shielded, downward-directed, warm-colored lights only where and when needed, often paired with motion sensors to balance effective illumination with minimal light pollution.

But all this lighting is useless if there's no one around to witness or report a crime, says Marcus Felson, a professor at Texas State University and an expert in criminal justice. The lights would only help robbers see their actions, he says.
Motion detectors are the best, but again the question is guardianship — are there people around who are likely to see or would the offender think he will likely be seen?

Felson says indoor lights can deter burglars from breaking in, but they often break in anyway after knocking on the door to see if anyone answers. Outdoor security lighting is effective if there are people — neighbors, pedestrians or police — to actually see suspicious activity.
"If you're in a rural area, you're basically in a secluded area — you're better off turning off because the lights would help an intruder actually see," Felson says. "Motion detectors are the best, but again the question is guardianship — are there people around who are likely to see, or would the offender think he will likely be seen?"
A good way to reduce home burglaries, according to Felson, is to introduce yourself to your neighbors so they'll be familiar with who goes in and out of the house. You can also tell them if you're out on vacation so they can look out for you, like Nolan did.
According to FBI statistics, most residential crime actually occurs in daylight. But most people are not aware of this and turn off their burglar alarm systems during the day, Felson says. This is when your neighbors come into play — particularly retired folks who stay at home, Felson finds in his studies.
Tips For Keeping Your Home Safe
During the day, turn off your outdoor lights and leave your alarm system on.
Install motion-detecting lights.
Set timers for your lights, TVs and radios to mimic human activity.
Get to know your neighbors.
Turn off your lights if there is no one around to see them.
Establish a neighborhood watch.
"If your neighbors are retired and you know them, that's the real good way," Felson says.
