The Insurance Institute for Highway Safety has discovered a problem with most new car headlights.

Therefore, they fail to get top rating.

David Zuby, a researcher at the institute, said: “The big thing that we found is that there is a large variation in the amount of light down the road. For instance, worst performing headlight, low beam only projects 130 feet down the road.

In contrast, the best performing vehicle, Toyota Prius v with LED headlights, projects 400 feet down the road. There are government regulations dictating how much light comes out of the bulb, but not necessarily where it goes and whether or not it is usable by the driver.”

Do you agree with this research?
