Q. I always cringe when I see people leave their lights on when they’re not home to deter would-be burglars. Does burning the bulbs for hours really prevent robberies?
A. Dearest Ron,
Environmental consciousness can be quite the balancing act. On the one hand, you certainly don’t want to be wantonly sucking up electricity. On the other, you don’t want to come home to a trashed house, either, to say nothing of the profound creepiness of having some criminal paw through your stuff. Let’s shed some light on the subject.
According to FBI crime statistics, of the 1.38 million home burglaries in 2012, the majority were committed during the day – when, presumably, having a light on wouldn’t have mattered as much. That’s because most thieves look for an unoccupied home above all else, and that’s (naturally) most common when residents are at work.
But if “Act casual and look occupied” is your house’s best strategy against burglars, then a pitch-dark abode in the waning daylight is a bit like a neon sign blazing “Up for grabs!” And pretty much every police department I surveyed while researching this question advises dwellers to keep lights (and/or TV and radio) on for at least part of the period they’re out and about.
