taillight condensation

**Taillight condensation** refers to the buildup of moisture or water droplets inside a vehicle’s taillight housing. This typically occurs when humid air enters the light assembly and then condenses on the inner surface of the lens due to temperature changes.

It is often seen as fogging or small water droplets inside the taillight. Mild condensation can be normal and may clear on its own, but excessive or persistent moisture can indicate a faulty seal, cracked housing, or ventilation issue.
