Laying hidden dangers for traffic safety.
So,
What should I do if my car lights fog up?
Very simple,
Don’t drive on the road right away;
Do not use the dryer to dry the headlight mask directly.
The correct approach is:
Turn on the headlights,
Wait until the fog clears before driving on the road.
Speaking of which,
Everyone must be curious about the reason why the car lights fog up.
Then come and take a look with Xiao 2!
Normally,
There are three situations when car lights fog up.
The first type: caused by excessive temperature difference
Cause analysis: Almost all headlights have a ventilation rubber tube on the back cover. This rubber tube is used to remove the heat generated by the headlights, thereby maintaining the normal operating temperature of the headlights. It is precisely because of the existence of this ventilation rubber tube that the moisture in the humid air will adhere to the inside of the lampshade, forming a layer of water mist. When the temperature difference is large, a large amount of accumulated water vapor will flow down the lampshade to form some accumulation. water.
Treatment method: Turn on the headlights and wait until the fog disappears. No other special treatment is required. It usually takes about ten minutes.
The second type: daily maintenance issues
Cause analysis: After wading the vehicle, washing the car, and cleaning the engine compartment, if the accumulated water is not completely dried or drained, the water may enter the headlight through the rubber tube.
Treatment method: Turn on the headlights and wait until the fog disappears. No other special treatment is required. It usually takes about ten minutes.
The third type: sealing problem
Cause analysis: If after encountering water, it is found that the amount of water in the headlight obviously exceeds the standard, forming a large amount of water, this situation can basically be judged to be a problem with the headlight seal, either the headlight cover or the back cover is damaged, or the lamp cover and The sealing strip of the rear cover is a problem.
Treatment method: Remove the headlight assembly, and carefully check whether the lampshade, back cover, and ventilation rubber tube are damaged. After confirming that there is no damage, it is recommended to peel off the lampshade and the assembly, dry them separately, and then reseal them.
Little 2’s warm reminder:
After a heavy rain or after washing the car, it is best to use a high-pressure air gun to blow into the corners of the engine compartment that are prone to moisture accumulation to speed up the air flow and take away the moisture accumulated in dark corners. In addition, it is not recommended that you directly use a high-pressure water gun to flush the engine compartment. This will make it difficult to remove the water. If it gets stuck in the hood, it will easily cause the headlights to fog up or water to enter.
