Headlight dimming o r fogging is a common issue in older Prius models, and it’s often caused by:

Aging Lenses: Over time, the plastic headlight lenses can yellow o r become foggy, reducing visibility.
UV Damage: Prolonged exposure to the sun can cause the lens coating to degrade, leading to cloudy headlights.

Solutions:

Headlight Restoration Kits: These kits can remove yellowing and restore clarity to headlights.
LED Headlight Upgrades: Consider upgrading to LED headlights for better brightness and longevity.
Protective Films: Apply UV-resistant headlight protection films to prevent future yellowing and fogging.
