Easy Steps to Clear Yellow Headlights

The yellowing headlight is a common issue that many drivers deal with. It’s the state in which the headlights become hazy and have a yellowish tint. The majority of automobile owners tend to ignore the issue until it becomes severe and compromises the brightness and range of the lights. For the best visibility when driving, you must understand how to remove yellow headlights.

What Is the Reason Behind Yellow Headlights?

You must comprehend the cause of headlight yellowing in order to identify the source of the issue. Oxidation is the primary cause of yellowing. The headlight assemblies on the majority of modern car models are composed of plastic.


It’s important to note that the outside plastic has an oxidation-resistant coating when brand-new. But eventually the coating peels off, making the area vulnerable to UV radiation.

Exposure to dirt is the second reason why the headlights are yellow. As previously mentioned, one method that debris damages this automotive component is by becoming lodged in surface fissures in the polycarbonate lens. It might potentially land inside, in which case you’ll need to clean the interior of the headlights.


Another reason for the blurry light assembly is gas exposure. When exhaust fumes land on the lens, they blur the image. One of the key factors is the density of these gasses.

Do headlights made of glass get yellow? Seldom do glass headlights become yellow. If they do, dirt or fume exposure is most likely the problem. Glass is more vulnerable to oxidation, which mostly affects assemblies made of polycarbonate.

The yellowing is caused in part by air exposure of the polycarbonate lens and UV radiation. Moreover, the surface of the lens may start to crack slightly as a result of the UV rays. The cover takes on a brownish appearance when dirt and other contaminants get trapped in the crevices.

If you choose to use baking powder to clean your car’s yellow headlights, use enough water to produce a thick paste that will work for both headlights. After a few minutes, apply the paste to the surface and rinse.

Another way to help is to take a vinegar bath. In a bowl, mix vinegar and water at a 2:1 ratio. Take off the headlight assembly and give them an hour or so to soak in the bath.
