I had my headlamps restored by a company in New Jersey called Windshield Wonder. They restored my headlights and now they look factory new. They came to my house and restored the lenses in my garage. They sanded my lenses and then applied two coats of some sort of lens restoration liquid. The total cost for both lenses was $85.00. They informed me that applying carnuba wax to the lenses twice a year will stop them from hazing. So far it seems to be working.
