- New federal rules are supposed to prevent ever-brighter car headlights from blinding oncoming drivers while also improving visibility — but they’ll take years or even decades to have an impact.
- These smart lights, known as Adaptive Driving Beam (ADB) headlights, use sensors to automatically change the shape, brightness and direction of their light without reducing drivers’ visibility.
- Some use a shutter system that shades part of the light beam, while others use a matrix-style system that can turn individual LEDs on and off as needed.
