If your headlights look frosted, yellow, or hazy, that's the polycarbonate lens oxidizing — UV exposure slowly destroying the factory coating. It happens to nearly every vehicle that lives outdoors in New England, and it does more than hurt the car's looks: clouded lenses cut your nighttime light output exactly when you need it most on dark, deer-crossing country roads.
Headlight restoration removes the oxidized layer by wet-sanding the lens through a controlled grit progression, then machine polishing it back to optical clarity and sealing it against future UV damage. Replacement lenses can cost hundreds of dollars each; professional restoration restores most lenses for a small fraction of that.
At our Londonderry shop, restoration is done off the car where possible, protecting your paint from sanding and polishing spatter. Most lenses respond dramatically — we'll assess yours and tell you honestly if a lens is too far gone for restoration.
Benefits & Practical Applications
Brighter, safer night driving
Clear lenses put light back on the road instead of scattering it into haze.
Far cheaper than replacement
Restoration returns clarity for a small fraction of the cost of new assemblies.
Better resale appearance
Yellow, hazy headlights age a whole vehicle; clear lenses reverse that instantly.
Sealed against UV
We finish with a UV-resistant sealant to slow the re-yellowing process.
Fast service
Most restorations are done same-day — no need to leave the car for long.
How the Process Works
Lens assessment
We inspect both lenses for cracks, moisture intrusion, and how deep the oxidation goes.
Protect & wet-sand
Surrounding paint is masked; the lens is sanded through a fine grit progression.
Machine polish
Polishing compounds bring the lens back to optical clarity.
UV sealant
A UV-blocking sealant is applied and cured to protect the restored surface.
Packages & Options
Per-pair restoration
Headlight restoration is quoted per pair and can be added to any detailing service. Severely damaged or cracked lenses may need replacement instead — we'll tell you upfront.
Foggy on the inside rather than outside? Internal moisture is a different problem — we'll assess it honestly before quoting.
Frequently Asked Questions
How long do restored headlights stay clear?
With the UV sealant we apply and reasonable care, results typically last a long time. Lenses that live outdoors 24/7 in New England sun and salt will eventually age again — we'll give you care tips to stretch the results.
Can every cloudy headlight be restored?
Most oxidation is restorable. Lenses with internal fogging, cracks, or failed seals need replacement — we inspect first and give you an honest answer.
How much does it cost compared to new headlights?
Restoration is typically a small fraction of the cost of replacement assemblies — often 10-20% — while restoring most of the light output. We'll quote your vehicle specifically.
How long does the service take?
Most headlight restorations are completed same-day, often within a few hours. It's an easy add-on to any detail.
