But did you know? There is a type of headlight that illuminates the road ahead without dazzling oncoming drivers.

Its core technology relies on the properties of a parabola.
What is a parabola?
Simply put, a parabola is a unique type of curve.
As the name implies, it describes the path an object traces when thrown horizontally from a height. When you light a candle 🕯️ and shine it at a wall, the light scatters. However, if you place a mirror behind the candle—specifically positioning the candle near the focus of a parabolic mirror—the light is neatly transformed into a parallel beam that projects far and bright. This is the magic of the parabola: light originating from the focus reflects off the parabolic surface and projects outward as a perfectly parallel beam. Focus: A specific point inside the parabola;
placing the light source here ensures the reflected light is most orderly.
ADB (Adaptive Driving Beam) headlights utilize this very principle.
In one common ADB design, each tiny LED light source is precisely positioned at the focus of a parabolic reflector. Light originates from the focus, strikes the parabolic mirror, and reflects as a parallel beam. This beam projects forward—far and bright—yet it remains confined strictly to the vehicle’s own lane.
