There are many things to consider when buying headlight protection film. The style of car you have is one thing to think about. If you have a particular shape of headlights and are having a hard time finding a protective film for it, you may want to consider a spray instead.  Keep in mind that your headlights should not have any scratches or blemishes before you apply the vinyl or the coating. The blemishes will make it harder for the vinyl to stick. If your headlights are already damaged, you should first perform headlight restoration and apply headlight sealant or clear coat. Believe it or not, adding headlight protection film adds value to your car. So, if you try to resell it, you’ll be able to sell it for a better price.  If you use your car a lot at night, you may want to consider headlight protection film as it helps with the fogginess of the night and will help you see better when you drive in the dark.
