How US Adaptive Headlights Work: The Tech Behind the Glare-Free High Beams
The magic of adaptive headlights lies in their sophisticated blend of hardware and software. It’s a system that acts as an intelligent partner, constantly working to give you the best possible view of the road. The process begins with a forward-facing camera, typically located near the rearview mirror. This camera is the "eyes" of the system, identifying the headlights and taillights of other vehicles.
This visual data is sent to a central control unit—the "brain." The brain processes the information in milliseconds, calculating the position, distance, and speed of other vehicles. It then sends commands to the headlight units themselves. Modern adaptive systems use an array of individual LEDs, each of which can be turned on, off, or dimmed independently. By precisely controlling this grid of LEDs, the system creates a dark "shadow" or "box" around other vehicles. Your high beams are effectively on all the time, but they are…
