At some point, you will start to find your new car’s bright and clear headlights turning yellow and hazing after some time of use. Take note that while there are some automobiles that use glass lenses for their headlights, there are also some cars wherein the headlight lenses are in plastic materials.  Therefore, plastic oxidizes very easily, which eventually turns yellow and hazes up when exposed to UV rays and harsh weather conditions.

Fortunately, there are several ways how to prevent these problems from happening so that you can keep your headlights as good as new. One of the effective ways to do this is to invest in high quality best headlight sealants. Using this item can save you more time and money. You no longer need to buy new headlights or bring your vehicle to the automotive shop.

Consequently, every sealant has a varying duration of longevity. This means that some sealants will perform efficiently for a longer time, while others may not last longer than a few months. 

Before buying the sealant, make sure to compare and weigh out the estimated longevity of the sealant against its price to see if it’s feasible.

● Ease of application

There are headlight sealants that require specific tools and materials for their application. For example, some sealants may not be used without syringes. These items can cause difficulty or inconvenience on your part, especially if you do not have any tools available at home.

Therefore, go for sealants that come with their own applicators or in spray/bottle packaging that ensures ease of application. 

● Purpose 

As mentioned at the beginning of this article, there are two headlight lenses: glass and plastic lenses. It is crucial to check first the quality or type of your headlight lenses before purchasing sealants. Keep in mind that not all sealants work on every surface, so you have to be careful in selecting one that works for you.
