After a typhoon, heavy rain, or melting snow, if you are careful, you may sometimes find that there is a layer of fog inside the headlights or taillights of your car. To exaggerate, it looks like it is filled with water. You can also raise a small fish in a fish tank!
This, what on earth is going on?
Don’t panic, let’s take a look at the reason first!
The headlights and taillights are indeed waterproof, but they are not completely sealed. Behind the lights, there is a specially designed vent pipe or vent to dissipate heat from the lights.
Because a large amount of heat is generated when the headlights are turned on and even during use. If there are no vents, the air inside the lights will expand due to heat and may burst.
In order to ensure the normal use of the headlights, the car will discharge the heat as much as possible through a ventilated rubber tube. However, moisture in the air can easily pass through the trachea, enter the headlight and adhere to the lampshade, forming fog. As the fog gathers, water droplets will flow down the lampshade. If not dealt with in time, in addition to It affects the brightness of the car lights and can also cause short circuits in the car lights and damage the circuit.
so what should I do now?
In this case, friends don’t have to worry too much. If it’s just the car lights fogging, it’s very simple to deal with. In fact, there is no need to deal with it. After the car lights are turned on for a period of time, they will also evaporate and be discharged out of the lamps along with the breather tube. , this will basically not damage the headlights and electrical circuits; if there is too much water inside the headlights, and there are still water droplets or water accumulation after turning on the headlights for a period of time, you should go to a professional repair center as soon as possible to dismantle and repair it. Generally, He said that most of the cars with water accumulation are old cars, and the sealant may have aged over time.
Aozim’s warm reminder: Do not bake the headlights, because there are a lot of plastic materials in the headlights. When baked at high temperature, it is easy to lose the life of the material and even burn out the headlights.
