What causes headlights to turn yellow?
Headlights turn yellow primarily due to prolonged exposure to sunlight and UV rays. Most modern headlights are made from polycarbonate plastic with a factory-applied UV protective coating. Over time, this coating breaks down, allowing the plastic underneath to oxidize and discolor.
Environmental factors such as heat, road debris, pollution, moisture, and frequent car washes also contribute to surface damage. These elements create microscopic scratches and accelerate oxidation, leading to a yellow, cloudy, or hazy appearance that reduces light output.
At Jay’s Mobile Headlight Restoration, we provide professional headlight restoration in Sacramento, California and surrounding areas, removing oxidation and restoring clear, bright headlights with long-lasting UV protection.
