Headlight restoration is a process that improves the clarity and brightness of vehicle headlights, which can become cloudy or yellowed over time due to exposure to UV rays, dirt, and environmental factors. This degradation can reduce visibility while driving at night, making restoration important for safety. The restoration process typically involves cleaning the headlight surface, sanding away the damaged layer, and applying a protective sealant. Various kits are available for DIY restoration, or professional services can be hired for more thorough results. Regular maintenance can help keep headlights clear and functional for longer periods.
