Why Do Headlights Become Foggy?
Headlights fog up due to oxidation, dirt accumulation, and exposure to the elements. Most modern headlights are made of polycarbonate plastic, a durable material prone to wear and tear. Over time, exposure to UV rays breaks down the surface coating, allowing dirt, grime, and moisture to settle in.
Factors that worsen headlight fogging:
- UV Rays: Sunlight oxidizes the plastic.
- Road Grime: Dust, mud, and pollutants build up over time.
- Moisture Intrusion: Cracks or loose seals allow condensation to form.
Knowing the root causes helps you take preventative measures to protect your headlights from future damage.
