Why Do Your Headlights Get Foggy?

Why Do Your Headlights Get Foggy?

Have you noticed anything wrong with your car lately? If nothing seems to be the problem in broad daylight, perhaps you’ll run into some issues later in the night, such as foggy headlights. And if you value your safety, you’ll want to remedy this as soon as possible, whether through regular maintenance or a brand-new set of LED bulbs for cars!

The dangers of driving with foggy LED bulbs for cars

How bad is it to travel with clouded or yellowed headlights? According to the American Automobile Association (AAA), cloudy headlights only generate around20% light compared to newer bulbs, leading to hazardous nighttime road conditions.

For instance, poor visibility due to foggy headlights may make it harder for you to identify roadway obstacles, including people and animals. On top of that, you’ll have trouble perceiving distances and reacting to fellow motorists.

If you are driving in the dark, it’s best to take things slow and remain alert until you’ve reached a brighter area.

Reasons why your LED bulbs for cars get foggy

With all that said, what really makes your car headlights cloudy? Here are some common causes:

1.   Oxidation

Headlight lenses are manufactured with hard topcoats that serve as protection from external elements. However, their top layers can quickly deteriorate, exposing the acrylic lens to UV light. When this happens, the plastic eventually turns yellow to yellowish-brown.

2.   Dirt and chemicals

Ifyou haven’t been to the car wash for a while, a thin layer of dirt and chemicals will start to form on your headlight’s lenses. This especially happens during the winter, when salt and road chemicals form a permanent layer on the surface.

3.   Water vapor

Headlights are tightly sealed to prevent water from entering the lens; however, this seal could break over time due to wear and tear. As a result, water droplets find their way inside the lens, eventually condensing and scattering beams of light.
