Xenon headlights produce light that is much closer to daylight and about twice as much as comparable halogen bulbs, and make night driving, particularly in poor weather, safer and less tiring for your eyes. Xenon headlights are standard on the Audi S3 Cabriolet.
The optional adaptive lights swivel in the headlamp cluster. When turning, they follow the steering wheel and cast a wider angle of illumination so you can see round the bend more clearly at night.
At the rear, the Audi S3 Cabriolet's lightweight LED tail lights offer greater visibility, penetration and an overall safer driving experience, as well as lasting longer than conventional halogen bulbs. Rear LEDs are available with Xenon headlights only.
