Why Is My Headlight Foggy Inside?

Just because your headlights are foggy or cloudy doesn’t mean they need to be replaced right away, but they can dim your headlights, which makes your vehicle less visible and it harder to see while driving.

While manufacturers have chosen to use plastic lens, these kinds of headlights need to vent heat from the bulbs. Because of these vents, moisture and condensation can collect inside the headlight, and over time your headlights can look foggy or cloudy inside. The best way to fix this is to install new headlights.
