04 passat headlights

The lenses on my passat have a fogg over them which makes the headlights very dim. Is there a product to clean them or how do I clean them?

Stop at the auto parts store. They have kits just for this.

Why O Why did they switch from the sealed headlamps to these fancy expensive short lived hard to adjust things on today’s cars. I vote to go back to a few choice 5 or 7 inch: dual (bright/normal) two lamp systems or single filament four lamp systesm!

Better aerodynamics, of course.
