How to Fix Foggy Headlights

Foggy headlights aren’t just a nuisance, they can actually pose a safety risk. They obstruct the beam from your car’s bulbs, making it difficult to see while driving at night or in bad weather.

Fortunately, there are several methods for restoring your headlights to their original condition. But what causes them to get foggy in the first place?

UV Radiation

Over time, UV rays from the sun can cause headlights to yellow and become hazy. This obstructs the light from the bulb and decreases visibility while driving at night or in bad weather. Keeping your headlights clean can help you stay safe on the road by ensuring that other drivers see your car, and that you can see the road well enough to make turns and avoid accidents.

While the plastic headlight lenses used on modern vehicles are much more durable than those on older cars, they still degrade over time from constant exposure to sunlight and other elements. This degradation process can be caused by many different factors, including exposure to UV rays, dirt, and chemicals that can be found in the air.

The acrylic covering on headlight lenses is usually covered with a clear layer that helps to prevent the oxidation that can lead to yellowing and haziness. Over time, this coating can wear off, exposing the plastic to UV radiation that quickly oxidizes the lens, turning it yellow and making it hazy.

This oxidation process can be prevented by using a spray designed specifically for headlights that contains UV protectant or parking in the shade whenever possible. It is also recommended that you wash your vehicle frequently to keep the buildup of dirt and other debris to a minimum.

Thankfully, there are a number of products available on the market that can restore headlights to their original luster. Typically, these products include a pre-cleaner to remove any tough gunk, followed by a plastic polish and then a sealant that will help to prevent future oxidation. Depending on the severity of your headlights, this process can take as little as 30 minutes to several hours, but will leave your headlights looking like they came straight from the showroom.

In addition to these commercial products, there are a number of DIY solutions that can be tried at home. These can include baking soda and vinegar washes, as well as off-the-shelf abrasive polishes.

Most modern headlights are made of polycarbonate plastic, which is tough and designed to handle road debris without breaking. But this strong material can also be damaged by environmental factors like oxidation, dirt, and chemicals that can eat away at the clear top coat and cause it to turn yellow or foggy.

Over time, this deterioration limits the ability of your car's headlights to project and emit light, reducing visibility and limiting how far they can illuminate. Restoring faded headlights is an easy, inexpensive fix that can significantly improve nighttime driving safety.

Foggy headlights are more than a nuisance, they're dangerous for drivers and passengers. They can reduce a vehicle's candlepower by up to 80 percent, making it difficult for other drivers to see the road and react quickly to potential hazards. It's important to clean your headlights regularly with a mild soap and water, and to keep them free of oxidation and other contaminants.

Dirt and debris are a major contributor to headlight fogginess. Gravel, pebbles, and other road debris can chip the clear layer of plastic over headlight lenses, creating teeny-tiny pits and dents that hold moisture, dust, and grime. These nicks and scratches can also cause headlight casing to become cloudy or yellow.

Oxidation can occur when headlights are exposed to air that has a high moisture content. The excess moisture causes condensation inside the headlight lens and can result in a foggy appearance. The best way to prevent this from occurring is to use a UV sealant on your headlights after cleaning and polishing them.

Most people don't realize how bad a set of dirty or foggy headlights can be for their driving safety. Using a professional headlight restoration kit or DIY methods to restore your headlights is the best way to protect yourself and others on the road. A restored headlight allows more of your car's light to reach the road, giving other drivers plenty of time to react and avoid a collision. It's also a good idea to have your headlights restored at least once per year to maintain optimal visibility.

Water Vapor

Headlights are essential for road safety at night and in foggy conditions. They help you see your way and make other drivers aware of your presence. Unfortunately, they can degrade over time and become hazy. This is a big problem as it significantly decreases the light they emit and can lead to accidents. Fortunately, it is possible to restore your headlights with a few simple steps.

The first step in restoring your headlights is to remove any dirt and debris from the casing. You can use a rag with soap and water or some automotive products specifically designed for headlight restoration. You will need to apply some pressure to the rag or brush in order to scrub away any stubborn stains. Once the stains have been removed, you can begin the second step in the process.

After scrubbing the surface of your headlight, you will need to rinse it with some clean water. This will help to clear the remaining debris and ensure that your headlights are free of any chemicals or residue left behind. Once your headlights are clean and dry, you can apply a UV sealant to prevent them from oxidizing again in the future.

One of the most common reasons that headlights get foggy is due to water vapor condensation. This happens when the headlight lens has a moisture content that exceeds its limit. Once this moisture reaches the headlight lens it causes a film to form that scatters the light beams from your car’s bulbs.

Over time, this will cause your headlights to appear dim or even yellow. This is not only an eye-sore, but it can also be a significant safety hazard as it reduces your visibility on the road at night.

Fortunately, it is relatively easy to restore your headlights and the procedure only takes a few minutes. Whether you want to tackle the job yourself or would rather leave it to a professional, there are many garages that offer affordable headlight restoration services. In the end, it is definitely worth the effort to keep your headlights looking their best.


Foggy headlights not only look dingy and ugly but they also limit your car’s visibility. This can be a major safety hazard for you and other drivers on the road. Fortunately, you can often fix this issue with a few simple steps. Let’s take a closer look at what causes your headlights to become yellow and hazy and how you can restore them back to their clear state.

Most modern-day headlights are made from a type of plastic called polycarbonate. This material is a lot more durable than the glass used in older cars and is designed to resist shattering. However, over time the outer layers of this plastic can begin to oxidize, which causes the headlights to turn yellow. This is due to a chemical reaction with the sun’s UV radiation and accumulated dirt within the housing.

Another common cause of hazy headlights is moisture or condensation. This is not a sign that your headlights are broken or in need of replacement from a Tempe mechanic, but rather a natural response to changes in air temperature. Typically, this occurs when the headlights are warm and then cool off. As a result, moisture collects inside the casing and then spreads throughout the lens.

This moisture scatters the beams of light from your bulbs, which can dim or even completely obscure them. Over time this can dramatically reduce your visibility, especially at night or in harsh weather conditions.

In addition to UV radiation, oxidation and dirt, other issues that can contribute to your headlights becoming yellow or hazy include cracks and leaks in the casing. These problems can be caused by wear and tear, impact damage, or a broken seal that allows water to seep in.

Once the cracked or leaked areas of your headlights are cleaned, they can be polished and buffed to remove any remaining yellowing or haze. You can purchase a special headlight polishing kit from your local auto parts store that will come with everything you need to revive your car’s headlights. Once the lenses are clean and shiny, you can apply a coat of automotive wax to keep them looking great for longer.
