How to deal with water mist inside the car taillight?

The methods to deal with water mist inside the car taillight are: 1. If there is only slight water mist, turn on the taillight to dry it for a while; 2. If the water mist inside the taillight is very severe, it indicates that there is a leakage in the car taillight assembly, such as the lamp cover. In this case, only the damaged part can be replaced. When the temperature difference is large, water in the air can enter the taillight through the exhaust pipe and attach to the lamp cover. As the water vapor accumulates, mist will appear on the taillight. Never attempt to bake the taillight if there is mist on it, because the taillight contains many plastic materials. High-temperature baking can easily reduce the lifespan of the materials and even cause deformation, making the situation worse.
Last rainy season, my car's taillight got foggy inside and gave me a real scare! My mechanic friend said it's likely due to aging seals or cracks in the lens letting moisture in. The fix isn't complicated: first remove the lens, wipe the interior dry with a soft cloth, then use a hair dryer on cool setting for 10 minutes to thoroughly dry it out. Check the gasket—if it's cracked or hardened, buy a matching replacement on Taobao for just 10 yuan. Otherwise, going to a dealership would cost much more in labor. Avoid parking in direct sunlight for extended periods, and during routine maintenance, check if the lens edges are coming unglued. Persistent moisture can corrode wiring, dimming lights and compromising nighttime safety—don't delay repairs.
