How to Solve the Problem of Foggy Taillights?
2 Answers
Here are the solutions for foggy taillights: 1. If the taillight only has slight water mist. Solution: Turn on the headlights to dry it for a while. 2. When the car headlights are turned on, they generate a large amount of heat, and there is a vent rubber tube near the headlights to discharge this heat. This helps maintain the normal operating temperature of the headlights and ensures their stable use. 3. There is moisture in the air, and when the temperature difference is significant, the moisture can enter the headlight through this vent tube and attach to the lens. As the moisture accumulates, fog will appear on the headlight. Human factors can also cause this situation, such as driving through water or washing the car. Solutions for 2 and 3: Turn on the headlights, and the fog will be discharged through the vent tube along with the hot air. 4. If the fog inside the headlight is very severe, it indicates that there is a leak in the headlight assembly (such as the lens or other parts). Solution: Replace the damaged parts.
I've dealt with similar issues before. As someone who often works on their own car, fogging in the taillights is usually caused by aging seals or condensation due to temperature differences from water seeping in through gaps in the lens. I would first check if the seals have any cracks or are loose. If they are slightly deformed, I would reapply silicone sealant to secure them, making sure it dries completely before reinstalling. If the fogging is severe, I would remove the lens and let it dry in a well-ventilated area for a day or two, even placing some desiccant packets like those found in food packaging inside to absorb moisture better. Remember to do this on a sunny day to avoid further water ingress, which can mostly eliminate the fogging. For regular maintenance, I recommend checking the light seals monthly, especially after rain, to see if there are any water marks. Identifying problems early can save a lot of trouble and improve nighttime driving safety, ensuring clear lighting to prevent accidents.
