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.

    Protect your headlights

    So far so good, best for sun protection.


    Great Product!! Easy to use!!

    Even with New Headlights.After applying two coats,running your fingers over the headlight you can feel the protective coating!! Finish with shining it up with a microfiber cloth!! They look better than when l took them out of the box, when l received them!!


    Convenient and good product

    It's a specific product to protect headlight lenses and other similar car polymers from the sun. It isn't easy to find this kind of product in the market. I like McKee's brand because they have very specific car products. Before using this product I recommend to apply a headlight cleaner and polish such as Meguiar's Plast X or McKee's 37 All In One Headlight Restoring products. The protectant spray is very easy to apply and I could verify that this product gave to the headlights an extra calrity and shine with a like new appearance. I use this protectant to the plastic panel of the dashboard idicators too as well as in any car transparent plastic that it can be exposed to the sunlight. The product is liquid and this can be an advantage because it can quickly spread when aplying.


    Works well

    Not a very exciting product to use, but at least it works! My headlights haven't clouded up yet. I apply it after my weekly wash.
