How can I keep my Audi A4's headlights from fogging up?

I have noticed that my Audi A4's headlights tend to fog up during humid weather. I am looking for a solution to prevent this from happening.

To prevent your Audi A4's headlights from fogging up, try using a headlight sealing kit. These can easily be applied to the headlight housing and will create a watertight seal, keeping moisture out and preventing fogging.

In addition to using a headlight sealing kit, you can also regularly clean your headlights with a mild soap and water solution. This will help remove any dirt and debris that can contribute to fogging.
