SENZEAL|Dealing with fogging of car lights in this way

In the season with a large temperature difference between the morning and evening, the water vapor that evaporates from the remaining heat during the day condenses into fine and dense small water droplets when it cools at night. Small water droplets adhere to the car lights, which can cause fog and reduce the brightness of the car lights. This is more common in the fall and winter seasons. What should we do when our car lights fog up? In this issue, SENZEAL will tell you these tips for defogging car lights.

Why do car lights fog up?
Car lights are not completely sealed structures with vents to balance the air pressure inside and out. Under the right conditions, for example, when driving on rainy days, the temperature on the inside of the glass lampshade rises due to the bulb glowing and heating up, and then the water droplets vaporize; the temperature on the other side cools dramatically due to rainwater washing over it and the water vapor contained in the air will condense and adhere to the glass lampshade. This is the process of fogging.

Handling method for fogging of car lights.

The first thing you need to do when your car lights fog up is to identify the cause.
1. You need to check if you have recently driven in the rain, waded in water or washed your car. In the above cases, it is likely that the reason why the car lights fog up is water ingress.

2. Check whether the car light is broken. During normal car driving, the lamps may be broken due to inadvertently being hit by stones brought up by other vehicles; it is also possible that the lampshade may be scratched by other vehicles, resulting in cracks and causing water vapour to enter more easily.

3. There is an issue with the sealing of the lampshade. It is possible that there is a problem with the gasket if the car light dust cover is not broken or cracked. The gasket is not sealing properly, causing the lights to seep in moisture and cause fogging. This factor is not as intuitive to troubleshoot and needs to be checked at an auto service shop.

4. The factor of water condensation. If it is not due to rain, wading, or washing the car, then it could be due to the difference in temperature between hot and cold caused by the weather, which creates water vapor that condenses on the lampshade and forms a water mist ultimately. This is just like when we drive in summer and winter when there is a big temperature difference between indoor and outdoor, water condensation will condense on the car windows. Generally, this happens when we use our lights. However, as the lighting system is used for more hours, the fog in the car lights will slowly dissipate. If the fog is slow to dissipate, there may be a problem with the light covers and gaskets. You need to use the method above to troubleshoot it.

Once we've found the cause of the fog on the car lights, we can use these methods to disperse the fog:

1. Turn on the car lights to let the heat generated by the glowing lights for baking. Afterwards, the fog will naturally dissipate slowly when exposed to heat.

2. If the fog is thick and during the day, we can use sunlight to raise the ambient temperature. At this time, the fog will also slowly dissipate. Even if there is heavy water vapor, it will evaporate slowly.
