Headlight brightness is a big factor in overall automobile safety.
When it comes to safety, Guthrie says to never neglect the little things.
“The amount of light you can actually see and the distance you can actually see and manage and make decisions is ultimately making you safer on the road," he said.
Consumer Reports says drivers going 60 miles per hour need 300-350 feet at minimum to see and react (brake) for something in front of their vehicle.
Consumer Reports did tests and found new-car headlights reach about 300 feet ahead on average. If illumination drops to just 20 percent, a driver may only see about 60 feet in front of the vehicle.
