How Often Should You Restore Headlights? Frequency, Benefits & What to Expect

Short answer: 2–3 years for most drivers.

The most-cited industry figure is 2–3 years between restorations for a properly sanded, compounded, and UV-sealed lens. That number comes up across detailers, mobile restoration operators, and the polycarbonate-lens manufacturers themselves, and it tracks what we see in our own work in Battle Ground and Vancouver, WA — most cars we touch don't haze back inside that window.

It is not a fixed interval, though. The clarity window depends on how much UV the lenses see, what the weather does to the sealant, and where the car lives day to day. A garage-kept commuter that washes weekly will stretch past three years; a sunbelt daily driver parked outside year-round may want a fresh seal much sooner.

That variability is exactly why the 12-month clarity warranty baked into every job matters — if the lens hazes back under normal use within a year, the seal gets redone on the house.

A restoration keeps the original lenses in place, while assembly replacement adds the cost of new parts and installation.

A worked example: Brighten Your Light offers Standard Restoration polishing for cloudy, hazy, or lightly yellowed lenses at $129 + WA sales tax per vehicle for both headlights or Heavy Oxidation polishing for deeply yellowed, rough, or heavily hazy lenses at $159 + WA sales tax per vehicle for both headlights, mobile at your driveway. Assembly replacement is a separate repair, and some vehicles need additional fitment work or partial bumper removal to swap the units.

Before booking: choose Standard Restoration at $129 + WA sales tax per vehicle for both headlights for cloudy, hazy, or lightly yellowed lenses or Heavy Oxidation at $159 + WA sales tax per vehicle for both headlights for deeply yellowed, rough, or heavily hazy lenses. The booking authorization displays that exact selection before checkout.

Functionally, the restored lens returns the same clarity as a new assembly for the same use case, keeps the original factory polycarbonate on the car (which is OEM-designed for that housing), and avoids the dealer parts delay.

The full price tiers and what each one includes are on the pricing page, and our service area map shows where we currently come to you around SW Washington. Both numbers lock in once you book — no upsell on visit day.

On visit day we pull up to your driveway or workplace lot with the generator, the sander and polisher, the UV-resistant sealant, and our lighting. You don’t need to provide power or shop access — the rig carries its own.

A full pair lands in about 90 minutes. We mask the surrounding paint, run the progressive sanding pass to take off the oxidised layer, machine-compound and polish the lens back to factory clarity, and lay down the UV-resistant clear-coat sealant before the keys go back in your hand.

Before-and-after photos go on file with every job, the 12-month clarity warranty is auto-applied, and the invoice arrives by email after the visit. The whole flow is spelled out (prep, payment, what happens if you need to cancel) on the FAQ page.
