The short answer
The best headlight restoration kits use a multi-step wet-sanding-and-polish process (rather than a single wipe-on coating) to actually remove the oxidized plastic layer, and the best of those also include a UV-blocking sealant to slow the haze from coming back.
Headlight lenses cloud up over years of UV exposure, turning clear plastic yellow and cutting how far your low beams actually reach at night. A good restoration kit can bring back most of that lost clarity for a fraction of the cost of new headlight assemblies, though the results only last if the kit includes a real UV sealant.

Our top pick, best overall
3M Headlight Lens Restoration System
A professional-grade, multi-step sanding-and-polish system that's become a benchmark for DIY restoration kits, built to be used with a drill for faster, more even results.
A simpler, hand-applied kit aimed at drivers who don't want to use a drill attachment, trading some speed for an easier, low-mess process.
A streamlined two-step compound-and-sealant kit from a trusted detailing brand, geared toward maintaining clarity on lenses that aren't severely oxidized yet.
A complete kit that pairs a heavier-duty restoration compound with a durable protective coating, aimed at drivers who want the clarity to hold up longer between redos.
Yes, on lenses that are hazy or yellowed from UV oxidation rather than physically damaged — a proper multi-step kit removes the clouded outer layer of plastic and can restore most of the lens's original clarity and light output.
Results typically last anywhere from several months to a couple of years depending on your climate and sun exposure, and how good the UV-protective sealant included in the kit is; kits without a real sealant step tend to haze over again much faster.
Yes — many kits are designed for hand application and will still clear moderate haze, though drill-compatible kits generally produce a more even finish faster, especially on heavily oxidized lenses.
No — restoration kits only address surface oxidation on the outer plastic lens; cracked lenses or headlights fogging up internally from a moisture seal failure need to be repaired or replaced, not polished.
Most drivers see haze start creeping back within one to two years, so it's worth checking your headlights' clarity each spring and doing a touch-up restoration or a fresh sealant coat before it affects nighttime visibility.
