Yellowed headlights are not just cosmetic. A hazy lens scatters the beam instead of throwing it down the road, which matters on unlit highway at four in the afternoon in December.
The lens is wet sanded in stages to take the oxidised layer off, then machine polished back to clear and sealed against UV so it does not go straight back to yellow. Both headlights are included. Lenses that have cracked or fogged on the inside cannot be fixed this way, and that gets checked before anything starts.

Questions about this service
The sealant slows it considerably. Without one they can haze again within a year, which is why it is included.
No. Internal fogging means the housing seal has failed and the unit needs replacing.
Considerably, on most vehicles. It is worth trying restoration first.
