Why are the headlights blurry?

Almost all headlight covers are made of polycarbonate plastic with a coating that protects against sunlight damage. However, this protective layer breaks down when exposed to sunlight. The resulting dullness and yellowing can reduce the headlight power by approximately 80%.

Depending on how much you drive during the day, your headlight covers will likely need to be replaced every three to five years. Where you drive the car most of the time can also affect this breakdown program. Sunny locations and strong sunlight at high altitudes will accelerate degradation.

Ideally, you should replace your headlights when you notice that your headlights are losing light. However, this solution can be expensive. AAA estimates the cost of headlight replacement to be between $130 and $430, depending on whether you do it yourself with aftermarket parts or professionally installed OEM parts. Fortunately, there is another option that is much cheaper.

How do you restore your cloudy headlights?

If you prefer to use materials you have on hand, it is recommended that you get paint tape, high-grit sandpaper (2500 and 3200 grit), polishing compound, a clean microfiber towel, and UV sealer before you begin.

The purpose of headlight restoration is to remove oxidation in the polycarbonate housing. You’ll start by washing and drying the headlights. Then tape around the headlights to avoid damaging your car’s paintwork. After that it’s time to start wet sanding with 2500 grit sandpaper..

Polish the composition until the headlight is clear. Then apply UV concealer to protect your newly cleaned headlights from the yellowing effects of the sun.
