Car lights are an important part of the car. They not only require beautiful appearance, but are also crucial to driving safety. If there is fog or water droplets inside the car lights, the lights will become blurred and affect driving, especially at night. I believe many car owners will encounter this situation. What is going on? Does it matter?
>>Why are there fog or water droplets inside the car lights?
① The headlight mask is not tightly sealed, causing water to penetrate. This situation is mostly caused by human factors. The car lights have been cracked due to collisions or are poorly modified. Water will leak out when the car is washed or rains. In addition, this kind of situation may occur if the assembly process is poor or the sealing strip is aging when leaving the factory.
②Caused by large temperature differences. Some new cars have foggy headlights after they are purchased, mostly due to this reason. Whether it is halogen, xenon or LED headlights, they are not sealed in an absolute sense. There is a ventilation rubber tube on the back cover of the light unit. When the headlights emit a large amount of heat, the heat is dissipated through this rubber tube to ensure that the headlights work properly.
Moisture in the air will enter the interior of the headlight through it and attach to the lampshade. The large temperature difference between the inside and outside of the lampshade will form water mist. This phenomenon is easier to form in winter and rainy seasons, just like fogging on car windows.
>>What effects will there be if there is water in the car lights?
① Directly affects the brightness of the light. Water droplets prevent the light from gathering, and the driver's vision cannot see farther and clearer when driving at night. If the time is longer, the lampshade will also turn yellow and oxidize, affecting the appearance of the headlights. Especially for xenon lamps and LED lamp sets, the light transmittance is greatly reduced. If you are on the highway at night, the safety risk is great.
②It will affect the life of the lamp unit. The connection lines of the light group are generally modular. Once water enters the line module, it will cause a short circuit. There are also natural risks associated with older vehicles.
>>How should it be handled?
① If there is just a layer of water mist, we can turn on the headlights and wait for a few minutes. If the water mist slowly dissipates, then there is no need to worry and it can be used normally. If it still cannot be relieved after an hour, you need to open the engine cover, unscrew the sealing cover on the back cover of the car light (actually, unscrew the bulb, you can tell by looking at it), and just bask in the sun. After that, screw on the sealing cover and it can be used normally.
② Excessive water droplets or water accumulation are relatively serious. In this case, it is recommended to check and repair. If there are quality problems, you should seek compensation from the manufacturer within the warranty period. If you have modified it yourself or had a collision, you will need a professional to repair and replace it.
Special attention should be paid to never baking the headlights. Doing so will not only easily damage the headlights, but may also cause the lampshades to soften and turn yellow. Because most lampshade materials are made of plastic, this kind of damage is difficult to repair.
