Do Headlight Restoration Kits Really Work?

Headlight restoration kits are quite popular when it comes to fixing hazy and yellow headlights. Some claim that they are just but a bandage for a much bigger problem while others swear by them.

Many people wonder whether headlight restoration kits actually fix the problem. The short answer is yes. This is especially if the only other option available is to replace your headlight covers. Headlight restoration kits are an inexpensive alternative that provides a temporary to semi-permanent solution.

Why do headlights turn yellow?

Headlights turn yellow due to a reaction between the polycarbonate plastic cover and UV rays. Most units come with a protective film when the vehicle is released from the factory. The film deteriorates with time due to exposure to excess sun, dirt, and debris.

It turns yellow and foggy, hence, reducing the amount of light that passes through. This can affect the driver’s visibility when driving at night and cause a crash. It can also cause a car to look old and reduce its value on the market.

The good news is that there’s a solution to the problem. That solution includes using a headlight restoration kit to remove the hazy film that forms on top of your headlights. Most kits cost anywhere between $10 and $15.

How do headlight restoration kits work

Headlight restoration kits work by removing the foggy layer of film that covers the headlights. This is achieved by buffing the surface using different grits of sandpaper. The sandpaper scrubs the foggy coating off the headlight to reveal a clean surface.

Using different grits of sandpaper allows you to achieve a smooth finish. The higher grit helps to smoothen out the scratches caused by the lower grit sandpaper. The latter has a coarser abrasive surface that helps to scrape off contaminants while the former has less abrasive materials for creating a smooth finish.

Once the film is completely removed, the last step is to polish the headlight cover and protect it from turning yellow again. Removing the hazy film leaves the plastic exposed. Polishing and applying a UV protectant replaces the clear coat that came from the factory and leaves the headlight in good condition.

How long do headlight restoration kits last?

Headlight restoration kits last between 4 and 12 months. Discoloration may start to occur after six months. Fortunately, the haziness will not be as severe as before and can be easily removed using other much less intensive methods.

Some last a year before the headlights turn yellow again. The best options guarantee improved illumination and light output from your headlights. This also enhances safety when driving at night.

Conclusion

Restoring your headlights works well if you know what to do. It is better than replacing your headlight covers which can be costly. Most kits include instructions from the manufacturer that can guide you through the process. If you prefer not to do it yourself, consider taking your car to a body shop. A professional can restore your headlights’ visibility by up to 90%.
