Car headlight seal

During the time when the car lights are sealed, there is often the appearance of heavy rain. After the rain, there is a mist of water in the headlights of my car; the mechanical seal of the pump thinks about the time when the car is foggy, and uses warm air to bake. Removed, I wonder if it also applies to car headlights? Because the car lights are not tightly sealed, the imported mechanical seals simply constitute water ingress during clean and rainy periods, and mists are formed when the temperature difference between the surface and the inside is large. It is best not to conduct high-temperature baking at this time. The materials of the car lights are usually plastic. If the baking temperature is too high, it may cause the surface of the car lights to soften and deform, which will affect the use and beauty. In addition, today's car lights are usually integrated. After the bright lampshade, there will be a back plate for maintaining the lamp body. High-temperature baking will also cause the glue between the two to melt and increase Possibility of water in the headlights. Generally speaking, the moisture in the car lights can quickly evaporate under the sunlight in daylight. If your car lights frequently show signs of water ingress, you should go to the service station to check the lamp body to see if the bumps have damaged the car lights and caused frequent water ingress.
