Don't Panic! Your brand-new PrismBeam smoked taillights have developed a thin layer of fog after a car wash or rain. Do you think you bought a defective product?

Stop! Before angrily contacting customer service for a return, read this article. In 90% of cases, this is a physical phenomenon, not a product defect.

1: Condensation vs. Leak (Key Distinction: Condensation vs. Leakage)

2: The Science of "Breathable" Lights

Why not a complete seal? Air expands and contracts with temperature changes; if it were a vacuum seal, the lampshade would crack. Therefore, the lamp must "breathe" air, which means moisture can get in, but that's precisely the purpose of the vents—to allow moisture to escape.

3: DIY Fixes for Stubborn Fog

For those who don't want to wait for it to air dry, try the following:

• The "Hair Dryer" Method: Open the dust cover and use a hairdryer (on low heat) to blow air into the vents to accelerate evaporation.
  
  
• The "Silica Gel" Hack: Highly Recommended! It is recommended that users insert 1-2 packets of silica gel desiccant (similar to the desiccant in a shoebox) inside the back cover of the headlight. This is the most effective long-term anti-fog solution.
  
  
• Check the Gasket: Check if the foam gasket on the back is properly secured during installation. This is the most common cause of water ingress in Civic and GT86 models (improper installation, not a faulty headlight).

4: Prevention & Maintenance

During the rainy season or when washing the car, avoid directing a high-pressure water gun directly at the vent.

Regularly check the rubber seals on the back for signs of aging.
