Customer-centric丨What is the solution to fog in the car lights?1

A new BMW owner asked about the fogging of BMW headlights and suspected that there was something wrong with his car. Is it normal for BMW headlights to fog?

For questions from car owners,

The editor will share with you some common knowledge about BMW headlight fog:

Why is there water mist inside the breathing headlights when it’s cold?

Because it has an air intake hole and an exhaust hole, it balances the air temperature inside the headlights when the headlights are on. Let the hot air go out and cool air in. (There is a filter sponge inside each hole)

When the outside air is humid, it is sucked into the car lights and the hot air is exhausted. When you turn off the lights, the temperature inside the car lights will be low, and the humid air will condense into water mist, which will adhere to the car lights. This is why you find fog in your headlights.

Causes of headlight fog

1. Fog caused by temperature difference changes

There is a breather pipe installed on the back cover of the headlight assembly. The thermally expanded gas is discharged through this channel, but sometimes some moisture enters the breather pipe, which causes slight fogging. This fogging situation usually occurs in winter, rainy season or foggy days.

In order to pursue better lighting effects, most headlights adopt lens type, which makes the light more concentrated. The moisture mainly accumulates on the mirror surface outside the lighting area, so it is easily discovered by car owners. Car owners do not need to panic after fog enters the car lights. Normally, it will not affect the normal use of the car lights.

2. Car washing or wading in water causes fog

In addition to temperature differences, fog in the headlights is often caused by wading in water or improper car washing. When cleaning the engine, you should use a wet towel to scrub it instead of flushing it directly with a high-pressure water gun.

In addition, frequent water wading by vehicles can also easily cause fog on the headlights. After the water depth exceeds the wheel, the water will enter the car lights from the breather pipe. Water entering the car lights will not only affect the lighting, but may also damage the headlights.

How to remove fog from car lights

When a car owner finds fog in the car lights, he first analyzes the cause of the fog. If it is caused by temperature difference or moisture, for example, if you use the car lights for too long at night, you will find fog in the car lights the next day. At this time, as long as the low beam or high beam is turned on for about 10 minutes, the fog in the car lights will slowly disappear.

Under normal circumstances, the moisture in the car lights will evaporate quickly when the lights are used normally or under sunlight. Never use the method of baking the lights to remove the fog, so as not to damage the lights.

For fog generated after washing the car or wading in water, be sure to turn on the car lights in time to allow the fog to evaporate. The fog in the car lights cannot be ignored for a long time. Car owners should develop the habit of checking the usage of the car lights.
