Your headlights look like they're covered in cataracts. That milky yellow haze cuts your night visibility by up to 80%.

$1,200 for the pair.
There's a better option. And nobody's telling you about it.
Why Headlights Get Foggy
Modern headlight lenses are made of polycarbonate plastic—lighter and more impact-resistant than glass, but susceptible to UV damage.
The factory coating that protects this plastic degrades over 5-10 years. Once it's gone:
- UV rays oxidize the plastic surface
- The surface becomes rough and pitted
- Moisture and dirt embed in the damage
- Light transmission drops dramatically
The result: That yellow, hazy, foggy look that makes your car look 10 years older than it is.
Restoration vs. Replacement: The Numbers
| Factor | Professional Restoration | Replacement |
|--------|------------------------|-------------|
| Cost | $75–$150 | $400–$1,200+ |
| Time | 1-2 hours | 1-3 hours + ordering |
| Longevity | 2-3 years | OEM: 5-10 years |
| Appearance | Like-new | New |
| Light output | 80-95% of original | 100% |
The Math
For a typical vehicle with $800 replacement headlights:
- Restoration every 3 years for 9 years: $450 (3 restorations)
- One replacement after 9 years: $800
Restoration saves $350+ over the vehicle's life—and that's assuming you actually need replacement after 9 years (you probably won't).
When Restoration Works (Most Cases)
Restoration is the right choice when:
1. The Problem is Surface-Only
Most headlight haze is oxidation of the outer surface. If you can't feel scratches or cracks, restoration will work.
2. The Lens is Structurally Sound
No cracks, chips, or internal moisture. The plastic itself is intact—just discolored.
3. Light Function is Normal
The bulbs work. The aim is correct. Only the lens clarity is the issue.
4. Budget is a Consideration
$150 vs $800-1200 is significant. Restoration delivers 80-95% of the visual and functional improvement.
This describes 90%+ of foggy headlight situations.
When Replacement is Necessary
Sometimes restoration won't cut it:
1. Physical Damage
Cracks, chips, or breaks in the lens need replacement. Restoration can't fix structural damage.
2. Internal Moisture
Moisture trapped inside the headlight housing indicates a seal failure. New housings are required.
3. Severe Pitting
Extremely damaged lenses (left in harsh sun for 15+ years) may be too far gone. The plastic itself is compromised.
4. Upgrade Opportunity
If you're switching to LED or upgrading to a style variant, replacement makes sense for the improvement.
The Professional Restoration Process
Here's what we do (and why DIY kits can't match it):
Step 1: Masking and Preparation
We tape off surrounding paint and trim to protect your finish. The restoration process can damage paint if it contacts unprotected areas.
Step 2: Wet Sanding (Multi-Stage)
Not just one grit—a progressive sequence:
- 800-1000 grit: Remove oxidation and pitting
- 1500 grit: Refine the surface
- 2000-3000 grit: Prep for polishing
This takes 15-30 minutes per headlight. DIY kits often include only one grit—inadequate for proper restoration.
Step 3: Polishing
Machine polishing with compound designed for plastic. This restores optical clarity and prepares the surface for coating.
Step 4: UV Coating Application
This is the critical step most DIYers skip.
Without a new UV-resistant coating, the plastic will re-oxidize within months. Our coating:
- Blocks UV damage
- Provides 2-3 year protection
- Creates smooth, hydrophobic surface
- Cures under UV light for durability
Step 5: Final Inspection
We verify even finish, no sanding marks, and proper clarity. The headlight should look new.
Total time: 1-2 hours for a pair.
Why DIY Kits Fail
The headlight restoration kit from the auto parts store costs $15-30. Sounds like a deal.
What's actually in the box:
- One or two sanding discs
- Small amount of compound
- Maybe a weak sealant
What typically happens:
- User sands unevenly (human arm isn't a machine)
- Switches to polishing too soon (scratches remain)
- Applies thin sealant (or skips it)
- Headlights look better for 2-3 months
- Oxidation returns worse than before
The economics: $25 DIY kit that lasts 3 months vs. $150 professional job that lasts 3 years. Professional is 6x better value.
Headlight Tinting: A Companion Service
After restoration, many customers add slight headlight tinting:
Benefits of Light Headlight Tint
- Custom appearance
- Additional UV protection
- Extended restoration lifespan
- Modern look
What We Recommend
- Light smoke: Most popular, maintains light output
- Clear PPF: Maximum protection, no appearance change
- Dark tint: Not recommended—reduces safety
Important: California law requires headlights to emit white light. Dark tints may be illegal.
Cost Breakdown: Our Prices
| Service | Price |
|---------|-------|
| Basic restoration (light oxidation) | $75–$100 |
| Standard restoration (moderate oxidation) | $100–$125 |
| Heavy restoration (severe oxidation) | $125–$175 |
| Restoration + clear PPF protection | $175–$250 |
| Restoration + light tint | $150–$200 |
Compare to replacement parts alone (before labor):
- Honda Accord headlights: $200-400/pair (aftermarket)
- BMW 3-Series: $400-800/pair
- Toyota Camry: $150-300/pair
- Luxury brands: $800-2000+/pair
The Safety Factor
This isn't cosmetic. Foggy headlights are a safety issue.
The numbers:
- Oxidized headlights can lose 80% of light output
- Night visibility drops from 200+ feet to under 75 feet
- Reaction time at highway speeds becomes critical
After restoration: Light output returns to 80-95% of original specification. You can actually see at night again.
How Long Does Restoration Last?
With professional restoration including UV coating:
- Average lifespan: 2-3 years
- Optimal conditions (garaged car): 4+ years
- Harsh conditions (outdoor parking): 18-24 months
When haze returns, we repeat the process—at a fraction of replacement cost.
