Definition
Adaptive lights are headlights that automatically adjust their beam to driving conditions: aiming the beam into curves as the wheel turns, dimming for oncoming or preceding vehicles, and reshaping the beam by speed. They improve visibility and reduce glare for other drivers.
Key facts
- Adapt the beam: low beam, motorway, curve, city or fog.
- Modern Matrix LED systems can turn off individual beam sectors to avoid blinding others.
- They do not replace fog lights when fog lights are legally required.
