In the pictures look like the Cayenne's headlights are a bit foggy and a little yellowed. Looking on the internets you restore them by wet sanding, then polish or clear coat. The longevity is a month to 6 months. The clear coat is rattle can clear coat. Friend that works in a local body shop says they do it for $200 for both headlights. They wet sand and use real body shop clear coat that is oven cured and is guaranteed for the life of the car.
