Over time, plastic car headlights can become foggy and discolored due to oxidation from UV light exposure. Fortunately, there are many do-it-yourself headlight restoration kits that can help brighten and clean your headlights.
Headlight restoration is important because it affects both how well you can see the road at night and how clearly other drivers and pedestrians can see you. A 2018 study by AAA showed that cloudy headlights only generate 20% of the amount of light that new ones do.
If your car headlights are beginning to yellow or look hazy, replacing them with a new set or going to a body shop with professional headlight restoration products and tools would give you the best results, but the costs could range from hundreds to thousands of dollars. Alternatively, DIY headlight restoration at home is a cost-effective and simple way to improve clarity and illumination.
