How to Replace a Car Headlight Cover?

Replacing a car headlight cover should involve removing the front protective grille before proceeding with the replacement. Here is a partial introduction on how to replace a car headlight cover: Old Headlight: Remove the old headlight, which requires first taking off the front protective grille. Several screws at the top and bottom need to be removed to take it off, usually along with the grille. Then, disconnect the power supply to the headlight assembly. Use the appropriate screwdriver to remove the headlight screws—typically, there are four screws. Using a Heat Gun: Soften the adhesive by heating it. Start by using a screwdriver to scrape around the edge of the headlight cover to loosen the glue. Then, insert the screwdriver from the pointed end and pry it open. Use both hands to gently and slowly separate the cover by applying force from both sides.
I just helped a friend replace the headlight cover last month, and the process wasn't actually difficult. First, you need to prepare a new headlight cover, plastic pry tools, and a screwdriver set. When removing the bumper, start by taking out the clips inside the wheel arch liner—the locations vary by car model. Cleaning off the old sealant is particularly troublesome; you'll need a heat gun to warm it up to around 60°C to soften it. Before installation, make sure to wipe the inside of the headlight housing—even a little dust can affect brightness. Finally, apply the sealant evenly—I chose weather-resistant silicone. The whole process took nearly two hours, and the key is not to rush, as plastic clips break very easily. Doing it yourself can save hundreds in labor costs, making it much more cost-effective than going to a repair shop.
