Why Do Car Headlights Fog Up and How to Fix It

Causes of Headlight Condensation

Car headlights, whether on a Hino truck or a Mazda sedan, can fog up due to several reasons, the most common being:

1. Temperature Differences: When it rains or the air is humid, outside moisture encounters the heat from the bulb and condenses on the headlight surface, creating fog.

2. Worn-Out Rubber Gaskets: Rubber gaskets prevent water and dirt from entering the headlight. If the gasket is damaged or worn, water can easily seep in and cause condensation.

3. Cracked or Broken Headlight Lens: A cracked lens due to impact or aging also allows water to enter the headlight.

4. Improper Installation: Incorrect headlight installation, especially after repairs or replacements, can lead to gaps that allow moisture to enter.

Important Notes on Handling Foggy Headlights

• Avoid cleaning the headlights when they are hot, as this can crack the lens.
• Regularly inspect and replace headlight gaskets to ensure proper water resistance.
• If the lens is cracked, replace it immediately to prevent water damage to other internal components.
