Over time, UV rays can oxidize the factory-applied clear coat on your headlights, rendering them dull and hazy.
Instead of replacing them, you can save hundreds of dollars by restoring them yourself with one of these under-$20 kits.
Based on personal experience, I recommend the Mothers NuLens Headlight Renewal Kit that uses a power drill to sand off the haze because it’s fast and easy to use. However, it doesn’t come with a replacement UV-blocking coat, so you’ll have to re-polish the headlights every once in a while.
If you’re willing to put more time and energy into the process for longer-lasting results, the Sylvania Headlight Restoration Kit comes with a replacement clear coat to protect your lights over time, but it requires sanding down your headlights by hand.

Driving at night is no fun (not to mention dangerous) when you can’t see where you’re going. Although you’ve probably blamed poor visibility on bad bulbs, the problem is more likely the headlight lens, not the lights themselves.

You can also opt for the manual Sylvania Headlight Restoration Kit that requires sanding by hand. It takes more time and effort, but it comes with a UV-blocking coat that will give you longer lasting results. I haven’t tested this personally, but it’s highly rated on Amazon (4.6 stars out of 5, from over 4,200 customers).
Painter’s masking tape: If you don’t have some, any one of these on Amazon will do.
Microfiber cloths: The kit you get may have towels and applicators included, but it’s always a good idea to have extras on hand for this job and other car-related …read more
