works as advertised!
Size: 1 Count (Pack of 1)
I purchased this kit to renew the headlights on my 2016 Nissan Frontier pick-up. The headlights had become slightly oxidized and dull -- not that bad but it was bothering me and for the price of the kit I figured it was worth the effort to attempt to renew them.
All I can say is -- WOW, what a difference. The end result looked like new -- clean, brilliant and bright.
Read the directions (2 or 3 times) and follow them EXACTLY. Total time for me from opening the kit to being done was about 2 hours and I was taking my time.
This kit is different in that the final step applies a UV resistant coating which really makes the glass super transparent.
Great investment in the time and money. I can't stop admiring my new (old) headlights!

Incredible Results! The "Z-Line" is Back!
Size: 1 Count (Pack of 1), Size: 1 Count (Pack of 1)
I’ve tried a few "wipe-on" fixes in the past, but the CERAKOTE® Ceramic Headlight Restoration Kit is in a completely different league. If you are tired of hazy, yellowed lenses and weak nighttime visibility, look no further.
📖 Instructions & Ease of Use
The first thing that stood out was the clarity of the instructions. The kit breaks everything down into a simple, step-by-step process. Even if you aren't a "car person," the directions are foolproof. They don't just tell you what to do; they explain why each step matters, which gave me the confidence to get the job done right the first time.
✨ Restoration Effectiveness
As you can see in my Before and After photos, the transformation is night and day. My headlights went from a dull, oxidized yellow to a factory-fresh, crystal-clear finish. It didn't just "clean" them—it completely rejuvenated the plastic.
🔦 The Real Test: Light Output & Beam Pattern
The most impressive part isn't just how the car looks, but how it performs at night. I’ve included a photo of my car parked against a wall in the dark to show the comparison:
Passenger Side (Restored): You can see a sharp, distinct cutoff line and the perfect "Z-line" pattern. The light is focused exactly where it needs to be on the road.
Driver Side (Not Restored yet): The light is completely distorted. There is no cutoff, just a messy blob of light that scatters everywhere, likely blinding oncoming traffic while providing less actual visibility for me.
Final Verdict
This kit doesn't just make your car look better; it’s a genuine safety upgrade. Seeing that crisp Z-line back on the wall proves that the clarity is internal as well as external. Highly recommended!

Like it came from the factory
Color: 2024-2025 Black
The texture and color matches the factory interior and the shape and size of the handle is a mirror image of the passenger handle from the factory. Installation is quick and easy - it takes only five minutes. Great product!
