How to Deal with Yellowing and Aging Plastic Headlights on a 2014 Sagitar?
2 Answers
You can polish the headlights and perform regular vehicle maintenance to clean dirt and dust from the headlight surface. Below are specific details about the Sagitar: 1. Vehicle Positioning: The Sagitar is a joint-venture A+ class sedan brand under FAW-Volkswagen, categorized as a compact car by Volkswagen. 2. Configuration: All models come standard with integrated high/low beam LED headlights. Higher-end models feature a grille ambient light design, along with the MDFS intelligent dynamic headlight assist system and AFS headlight cornering system. 3. Interior: The cabin combines soft-touch materials and piano black lacquer panels. Higher-end models are equipped with a 10.2-inch Active Info Display instrument cluster and an 8-inch multimedia screen angled toward the driver, supporting Apple CarPlay connectivity. Base models do not include a multimedia screen and use touch-sensitive buttons for the air conditioning panel. Mid- and lower-tier models feature traditional analog instrument clusters.
After noticing the yellowing headlights on my 2014 Sagitar, I decided to DIY the restoration. The method involved first washing off surface dust with water, followed by wet sanding with 600-grit sandpaper, gently rubbing back and forth to remove the oxidized layer, then upgrading to 1200-grit sandpaper for a smooth finish. Next, I applied professional car polishing compound and repeatedly wiped it with a soft cloth until it became transparent and shiny. The entire process was time-consuming but low-cost, with tools costing only a few dozen yuan. The results were remarkable—the lens was restored to like-new brightness, significantly improving nighttime driving visibility. For prevention, I recommend parking in the shade or using a car cover to block sunlight, as UV rays are the main cause of aging. The plastic material of this generation of Sagitar headlights is soft and prone to yellowing, so regular cleaning and waxing can help delay the issue.
