While using a hairdryer is a quick fix, other methods may offer more permanent solutions:

Silica Gel Packets

• Place silica gel packets inside the headlight housing to absorb moisture.
• This method is effective for long-term moisture control.

Ventilation

• Ensure proper ventilation by checking and clearing any blocked vents.
• Proper air circulation can help reduce condensation buildup.

Resealing Headlights
