Almost everyone who drives at night has experienced it. You are cruising down a dark road when a car approaches from the opposite direction, and suddenly it feels as if someone is shining a flashlight directly into your eyes.

Modern headlights are not necessarily breaking the rules, but they are exposing a growing challenge that affects millions of drivers every night.
