Studies show bicycle helmets and lights are legitimate ways of staying safe on the road. This morning, a friend sent along this video from Healthcare Triage in which Dr. Aaron Carroll breaks down a couple health-related studies on bicycle crashes and injuries—and finds that both wearing helmets and putting permanent running lights on bicycles helps cyclists avoid crashes and injuries.

“Over the course of a year, the influence of accidents for those with the running lights was 19 percent lower,” he says of a 2013 study comparing bicyclists using lights to those who did not.

Check out this video below—and remember, while helmets are seriously recommended by the Bicycle Coalition, turning on bike lights at night is the law in Pennsylvania.
