When a customer calls a dealership about foggy headlights, the answer is almost always the same: "You need new headlight assemblies." And at $300–$800 per side, that's a significant upsell.
The truth is, the vast majority of headlight degradation is a surface issue — oxidation on the outer polycarbonate lens — and it's fully reversible with professional restoration. Here's how to think through the decision.
The Cost Comparison
Let's start with the numbers:
- Professional headlight restoration: Starting at $99 for both headlights
- Aftermarket headlight assembly (per side): $80–$250 + labor ($100–$200)
- OEM headlight assembly (per side): $200–$600 + labor ($100–$200)
- Dealer replacement (per side): $400–$800 all-in
For a pair of headlights, you're looking at $300–$1,600 for replacement versus $99–$150 for professional restoration. That's a meaningful difference — especially when restoration delivers the same visual result in most cases.
When Restoration Is the Right Call
Restoration works when the damage is limited to the outer surface of the lens. This covers the overwhelming majority of cases:
- Yellowing or amber discoloration from UV oxidation
- Cloudy or hazy appearance
- Light to moderate surface scratches
- Peeling or failing UV coating
If the lens is structurally intact — no cracks, no chips, no broken housing — and the hazing is on the outside, restoration will make it look like new. We apply a professional-grade UV ceramic coating at the end of every job, which protects the lens for 2–3 years.
When Replacement Is Necessary
There are situations where replacement is the right answer:
- Internal fogging: Moisture or condensation trapped inside the sealed housing that can't be reached from the outside
- Cracked or shattered lens: Physical damage to the polycarbonate that can't be sanded out
- Broken housing: Structural damage to the headlight assembly itself
- Deep internal hazing: In rare cases, the inner surface of the lens degrades — this is uncommon but not unheard of on older vehicles
If you're unsure which category your headlights fall into, a quick inspection will tell you. We offer free assessments — just text us a photo.
The Longevity Question
A common concern: "If I restore them, how long will they stay clear?" With a quality UV coating applied after restoration, you can expect 2–3 years of clarity. Without coating, oxidation returns within 6–12 months.
New headlight assemblies also have a UV coating from the factory — but that coating degrades over time just like the original. A brand-new OEM assembly will start showing oxidation within 3–5 years in Colorado's high-UV environment. So replacement doesn't eliminate the problem; it just resets the clock.
The Bottom Line
If your headlights are hazy, yellow, or dim — but structurally intact — restoration is almost certainly the better value. You'll get the same visual result for a fraction of the cost, with a UV coating that protects the investment.
Save replacement for situations where the damage is structural or internal. Everything else is a restoration job.
