How Do You Remove Water from Inside Headlights

How Do You Remove Water from Inside Headlights?

Many drivers and friends have encountered the fog inside the car headlights. At this time, the headlights are like watery eyes, which makes people feel pity. What the hell is going on, how can it be wrong like this? Are the headlights not well sealed, causing water to enter the headlights, or the lampshade is damaged, and water vapor has penetrated into the headlights?
As far as the overall structure of the headlights is concerned, whether it is an ordinary halogen headlight, a xenon headlight, or a headlight with an LED light group, there is a vented rubber tube at the position of the back cover. At the moment when the headlight is lit and even when the headlight is in use, it will generate a lot of heat. The function of the vent pipe is to discharge this heat out of the headlight as much as possible to maintain the normal working temperature of the headlight and ensure the use of the headlight stable.


Because of this snorkel, through which moisture in the air will enter the headlight and attach to the lampshade. As the water vapor gathers, the water droplets will flow down the lampshade. Most of this situation is caused by large temperature differences. This phenomenon is most likely to occur in winter and rainy seasons. In this case, the driver's friend need not worry too much. After the lamp is turned on for a period of time, the mist will be discharged out of the lamp with the hot air through the vent pipe, which will basically not damage the headlights and electrical circuits. Do not bake the headlights. This is easy to damage the headlights because the headlights are made of plastic, and the extra heat can easily roast the lampshade. Most of these injuries are irreparable.

In addition to changes in the weather, human factors can also cause the lights to become "tears", such as vehicles wading and washing cars. When the vehicle is wading, because the engine and the exhaust system are both relatively large heat sources, rainwater will form a large amount of water vapor on the top. The water following to the snorkel, part of the water vapor will enter the headlights.

And car washing is more direct. Some car owners like to use high-pressure water guns to flush the engine compartment. Watching the sludge and leaves are repelled one by one with high-pressure water guns in their hands. After washing, the accumulated water in the engine compartment is not dealt with in time. After the engine compartment cover is covered, the water vapor cannot be quickly dissipated outside the vehicle, and the water vapor in the engine compartment may enter the headlights.

For the cleaning work in the engine compartment, we should use more cotton or cloth to wipe, or use high-pressure air blowing, as far as possible to avoid the engine parts "tide".
The above mentioned are all relatively light water in the lamp, but if the water accumulation inside your car headlight is enough to raise fish, then you need to disassemble and open the lamp cover, after drying, check the large Whether there is any damage or possible leakage on the surface of the lamp. If no abnormality is found, we generally recommend replacing the sealing strip and vent pipe of the headlight back cover.
In winter and rainy seasons, it is best for car owners to develop the habit of regularly checking their lights. For example, it is necessary to check the vehicle after wading. Early detection and early remediation, and timely elimination of failures in the budding stage, this is the only choice for keeping a car.
