I think we can all agree that hazy headlights are aggravating. No one likes the crusty look or the light output reduction. In this post we will explore why headlights haze, and how we can use Lamin-x film to stop them.
Why do my headlights haze?
It is time for technical speak. Before we begin, lets give a brief history of headlights.
The original headlight lenses were made from glass. Glass headlights ruled for years, until 1983 when plastic headlights became legal. Car manufacturers jumped on the opportunity to use polycarbonate plastic for headlights. Polycarbonate is much more easy to form into aerodynamic shapes than glass, as well has having higher impact resistance. Unfortunately, polycarbonate does not weather well. It is a porous plastic and has very little UV resistance. So, after a while, polycarbonate will begin to degrade from the sun’s harmful UV rays. During this degrading process polycarbonate’s molecular structure breaks down and the result is that nasty looking haze.
Car manufacturers realized that polycarbonate couldn’t withstand UV exposure for a long time without degrading, so they came up with a simple solution. The solution being a thin, clear coat to protect the polycarbonate lens from the sun’s rays. The clear coat itself can degrade in a few years time and therefore leave your headlights unprotected. As we already know, the unprotected polycarbonate will then begin to break down at the expense of your lights and their light output.
What can I do to stop my headlights from hazing?
Hazy headlights can normally be fixed with a simple headlight restoration. For more information on headlight restoration go to our Headlight Restoration blog post. However, like brushing your teeth, headlight restoration will need to be done consistently to keep the headlight looking new. Don’t get me wrong, the headlight restoration will clear the headlights up. However it doesn’t stop the overall problem: the sun’s UV rays degrading the plastic.
The best option for clearing up your headlights is to install a protective film, such as Lamin-x, over the lens directly after performing a headlight restoration. Lamin-x film will provide a long-term protective layer, to protect the headlights for years longer than the original clear coat. With Lamin-x film applied to your headlight, the plastic lens will remain in its improved condition until the film is removed.
Lamin-x is better than your original clear coat because of its extreme UV resistance. Backed by a five-year warranty, our product is designed to take extreme abuse so your headlight lenses don’t have to. Your car doesn’t have to have hazy headlights, that is why we are here.
