Our static cornering lights provide an extra light source behind the headlight reflector. When you turn the steering wheel, or indicate, a small additional reflector with a separate halogen bulb lights the area you're turning into, over several metres at an angle of 35 degrees. As a result, the driver spots potential hazards sooner and more easily. The static cornering light's clear signal effect also alerts other road users.
