Protects headlights and prevents UV-induced fading

McKee's 37 Headlight Protectant Spray is a polymer sealant that blankets your headlight lenses in a clear, durable film of protection. Advanced cross-linking polymers seal the pores of plastic headlight lenses to prevent degradation caused by UV rays, water, and environmental pollution. Use on clear plastic headlight lenses, vinyl windows, and motorcycle windscreens. Treated surfaces will resist yellowing, fading and discoloration.

McKee's 37 Headlight Protectant Spray is your best defense against UV-induced fading and discoloration. If you drive a vehicle that was manufactured in the last 30 years, it most likely has headlight lenses that are constructed out of polycarbonate plastic. Polycarbonate plastic, while extremely durable and resilient against abrasion and impact, has poor resistance to UV rays, causing it to yellow and fade overtime, reducing visibility at night. Regular application of McKee's 37 Headlight Protectant Spray will ensure your plastic headlight lenses retain optical clarity, providing a clear view of the road ahead.

McKee's 37 Headlight Protectant Spray is quick and easy to apply. Simply mist a small amount directly onto the headlight lens and evenly distribute using a microfiber towel. If any overspray accidentally lands on paint, glass or plastic, it will wipe right off without staining. McKee's 37 Headlight Protectant Spray is hyper-concentrated so even an 8 ounce bottle will last years.

McKee's 37 Headlight Protectant Spray is designed for plastic headlight lenses that are free of oxidation and yellowing. If necessary, polish your headlights first using McKee's 37 All In One Headlight Restoring Polish. This step will restore optical clarity, giving McKee's 37 Headlight Protectant Spray a clean surface to bond to. If your vehicle's headlights don't need polishing, you can go ahead and apply McKee's 37 Headlight Protectant Spray. Treating new headlights before they fade and discolor can save you a lot of hassle in the long run.

McKee's 37 Headlight Protectant Spray can also be used on instrument panels, vinyl convertible windows, plastic windscreens, goggles, visors, motorcycle headlamps, fiberglass, Plexiglas, acrylic, and all clear or colored plastics.


  1. Ensure surface is clean, cool to the touch and free of oxidation or yellowing. If necessary, polish lenses first using McKee's 37 All In One Headlight Restoring Polish.
  2. Spray product directly onto surface and evenly distribute using a microfiber towel.
  3. Flip towel over and lightly buff area.
  4. Apply a second coat to ensure even coverage.

    Headlight Protectant Spray

    My headlights on my 2018 Mini Countryman are decent, but I bought the Protectant spray to slow the oxidation process. After I wash my car I apply the product to my headlights which takes about 5 minutes. Easy, Breezy. When the time comes that I need to restore the lenses, I will definitely purchase the Kit from McKee's. Great Service......

    Been Using It For Years

    Too soon to tell

    Easy to use. The true test will be the longevity of our headlights. Ask me again a year from now and again 5 years from now. I will continue to apply the protectant at least once per month.
