What Causes Headlights to Yellow?

Headlights turn yellow for several reasons. The most common reason is simply aging. Over time, the clear plastic that makes up headlights begins to oxidize and turn yellow. This process is accelerated by exposure to UV light, which is why you might notice that your headlights look more yellow in the summer than in the winter.

Another common reason for yellow headlights is road debris. Small rocks and other bits of debris can chip away at the clear plastic, causing it to turn yellow. Likewise, if you regularly drive on dirt or gravel roads, your headlights are more likely to become yellowed.

Additionally, some car cleaners and polishes can cause headlights to be yellow. If you regularly use these products on your car, the headlights may turn yellow more quickly. The other main reason for yellow headlights is improper care. If you don’t regularly clean your headlights, they can become caked with dirt, grime, and other debris.

This not only makes them look yellow, but it can also make them less effective at lighting up the road ahead of you. Lastly, if you don’t properly protect your headlights, they may become scratched or pitted, which can also cause them to turn yellow.

Why Should You Stop Headlights From Yellowing?

Aside from the fact that yellow headlights are unsightly, there are a few other reasons why you should try to stop them from yellowing. First, yellow headlights can reduce your visibility while driving at night. If your headlights are significantly yellowed, they can cause glare and make it difficult to see other vehicles on the road. This can lead to accidents. Second, yellow headlights can also reduce the lifespan of your headlights. The yellowing is caused by a build-up of UV rays, dirt, and other debris.

This can cause the headlight to crack and eventually break. Third, yellow headlights can decrease the value of your vehicle. If you plan on selling or trading in your car, yellow headlights will likely result in a lower offer. Finally, yellow headlights are just plain ugly. If you want your car to look its best, you should try to keep your headlights looking new.

10 Ways How to Stop Headlights From Yellowing:

1. Keep Your Car Clean

One of the best ways to prevent yellowing headlights is to clean your car. This includes washing both the exterior and interior of your car regularly. To do this, you can use various car cleaners and polishes. First, wash the exterior of your car with soap and water. Then, use a cleaner or polish specifically designed for cars to clean the interior. This will help remove any dirt, grime, or debris that could cause your headlights to be yellow. Finally, be sure to vacuum the interior of your car and clean the windows to allow as much light as possible.

2. Use a Headlight Protectant

Another way to prevent yellowing headlights is to use a headlight protectant. This is a clear coating that you can apply to your headlights. It will help protect the plastic from UV rays, dirt, and debris. There are many headlight protectants on the market, so be sure to choose one that is specifically designed for headlights.

First, clean your headlights with soapy water and a microfiber cloth. Then, apply the headlight protectant according to the manufacturer’s instructions. If you live in an area with many suns, you may need to reapply the headlight protectant every few months.

3. Apply a Uv Protectant

The sun’s ultraviolet (UV) rays can cause your headlights to be yellow, so protecting them from the sun is important. One way to do this is to apply a UV protectant to your headlights. This clear coating will help block out the sun’s UV rays. Many different brands of UV protectants are available, so be sure to choose one that is compatible with your vehicle.

Protecting Them from the Sun

First, clean your headlights with soapy water and a microfiber cloth. Next, apply the UV protectant according to the manufacturer’s instructions. If you live in an area with a lot of suns, you may need to reapply the UV protectant every few months.

4. Avoid Harsh Chemicals

Harsh chemicals can cause your headlights to be yellow, so it’s important to avoid them. This includes household cleaners, car wash solutions, and even some soaps. If you must use a cleaning product on your headlights, make sure it is designed for automotive use and gentle. If you are unsure, test the product on a small area of the headlight before using it.

5. Store Your Car in a Garage

Store Your Car in a Garage

If you have the option, store your car in a garage or covered area. This will help protect your headlights from the sun’s UV rays and from debris. Consider investing in a car cover if you don’t have a garage. Be sure to choose one specifically designed for your vehicle and covers the headlights.

6. Use a Microfiber Cloth

When cleaning your headlights, be sure to use a microfiber cloth. This type of cloth is gentle and will not scratch the headlight. It is also effective at removing debris and dirt. To clean your headlights, first wet the microfiber cloth with soapy water. Then, gently scrub the headlight in a circular motion. Rinse the headlight with clean water and dry it with a clean microfiber cloth.

7. Apply a Headlight Restoration Kit

If your headlights are severely yellowed, you may need to use a headlight restoration kit. These kits usually come with sandpaper and a polishing compound. You’ll need to use sandpaper to sand down the yellowed layer of plastic and then use the polishing compound to restore the headlight’s shine. If you’ve never used a headlight restoration kit before, be sure to read the instructions carefully. It’s also a good idea to practice on a small headlight area before doing the entire headlight.

8. Wax Your Car

Waxing your car can also help prevent yellowing headlights. This is because the wax will create a barrier between the headlight and the elements. Waxing your car regularly will help to keep the headlights looking clear and new. First, wash your car and then dry it completely. Then, apply a thin layer of car wax to the headlight. Allow the wax to dry and then buff it off. Repeat this process every few months to keep the headlights looking clear.

9. Polish Your Headlights

Polishing your headlights can also help to prevent them from yellowing. This is because the polish will create a barrier between the headlight and the elements. You can use a commercial headlight polish or make your own by mixing equal parts of baking soda and water. Apply the polish to the headlight with a soft cloth, and then buff it off. If your headlights are very dull, you may need to repeat this process a few times.

10. Apply a Sealant

Applying a sealant to your headlights can also help to prevent them from yellowing. This is because the sealant will create a barrier between the headlight and the elements, including UV rays. There are several different sealants available on the market, so be sure to choose one that is specifically designed for use on headlights. Sealants can be applied similarly to polishes, so be sure to follow the instructions on the packaging. Once applied, the sealant will need to be left to dry for some time before being buffed off.

How Much Does It Cost to Fix Yellow Headlights?

The cost of fixing yellow headlights can vary depending on the severity of the problem and the chosen method of repair.

If you choose to have a professional fix your yellow headlights, the cost can range from $100 to $300.
