First available in the early 2000s, adaptive headlights are designed to light up the roadway around a corner or over a hill when driving in low-light conditions such as dusk, sunrise, or during the night. Vehicles with adaptive headlights are equipped with sensors that detect the degree to which a vehicle is turning a corner or ascending a hill and then direct small motors attached to the headlights to turn the beams to the left, right, up, or down according to the direction of the vehicle.
