Because it has an air inlet and an air outlet, it can balance the air temperature when the Volkswagen Car headlights are on. Let the hot air go out and the cold air come in.

1. Fog caused by temperature difference changes
The rear cover of the Volkswagen Car headlight assembly is equipped with an exhaust pipe. The thermally expanded gas is discharged through this channel, but sometimes some moisture enters the exhaust pipe, causing slight fogging. This kind of fog usually occurs in winter, rainy season or foggy days.
In order to pursue better lighting effects, Volkswagen Car headlights mostly use lens type, which makes the light more concentrated. Moisture is mainly concentrated on the mirrors outside the lighting area and is easily discovered by the owner. Car owners do not need to panic when fog enters the headlights of Petrol Car. The normal use of Volkswagen Car headlights is generally not affected.
2. Heavy fog caused by car washing or wading
In addition to temperature differences, fog entering the headlights of Petrol Car is more often caused by wading in water or improper car washing. When cleaning the engine, scrub it with a wet towel and do not flush it directly with a high-pressure water gun.
In addition, frequent water wading by vehicles can easily cause Volkswagen Car headlights to fog up. After the water depth exceeds the wheels, the water will enter the Volkswagen Car headlights from the breather pipe. Water entering the headlights of Petrol Car will not only affect the lighting, but also damage the headlights of Petrol Car.
When car owners find that there is fog in the headlights of Petrol Car, they first analyze the cause of the fog. If it is caused by temperature difference or humidity, for example, if you use the lamp for too long at night, you may find that there is fog in the lamp. At this time, as long as you turn on the low beam or high beam for about 10 minutes, the fog in the Volkswagen Car headlights will slowly disappear.
Normally, the moisture inside the lamp will evaporate quickly under normal use or exposure to sunlight. Never bake the lamp to remove fog to avoid damaging the lamp.
For fog generated after washing the car or wading in water, be sure to turn on the lights in time to evaporate the fog. The fog in the headlights of Petrol Car cannot be ignored for a long time. Car owners should develop the habit of checking the use of Volkswagen Car headlights.
