U.S. Headlights Shown to be Darker, More Dangerous

The American Automobile Association (AAA) recently published a report that examined the safety of vehicle headlamps and compared headlamps in Europe to those in the United States. Researchers were particularly looking at how U.S. and European specifications for low and high beam headlamps differ in static roadway illumination, producing glare and dynamic roadway illumination. The study found that during testing of static roadway lighting, the average headlamp lighting levels were 12.5% higher in European specifications than the United States specification systems. Furthermore, European specification systems performed better consistently when vehicles were approaching and preceding vehicles were in close proximity.
