I believe that many friends will find that the headlights sometimes fog up when using their cars. This phenomenon often occurs after rain or after washing the car. In fact, it is normal for car headlights to fog up. You don’t need to worry too much. In this issue, we will discuss how to fog up the headlights. Let me teach you a few ways to solve the problem of foggy headlights.
First of all, the fogging of the headlights is due to changes in the outside temperature that cause the temperature inside the lamp unit to drop. At this time, water molecules in the air can easily enter the cavity of the lamp unit through the rubber vent pipe or vent hole, causing the temperature difference between the inside and outside of the lampshade to be too large, causing moisture. Water molecules in the air will gather from places with high temperatures to places with low temperatures, and the humidity in these parts will increase, and then condense on the surface of the inner lampshade to form mist. In addition, after the vehicle wades into water, due to the high heat generated by the engine and exhaust system, a large amount of water vapor will be formed on the water, causing some of the water vapor to enter the headlights.
If you want to solve the problem of headlight fogging, you can turn on both the high and low beams of the vehicle headlights. At this time, the headlights will generate heat to dry out the water mist. If you are not in a hurry to solve the problem of headlight fogging, you can leave it alone for the time being, because the headlights Fogging will generally dissipate naturally after a period of time and does not require special treatment. However, the fundamental solution to the problem still lies in the design of the car lights. For example, improving the air vents can reduce the amount of water entering the lamp cavity, or applying anti-fog spray treatment inside the headlights to avoid water mist condensation.
