Causes of fogging/water in headlights
Causes of foggy headlights:
The fogging of the headlights is due mainly to the high humidity of the air, which causes the water vapor in the air to condense in the headlights. At this time, the fogging of the headlights is a normal phenomenon. The reason for fogging is only related to the humidity of the air, not due to car washing, rain, snow, etc. Generally, there is not a lot of water vapor condensed in the fogging of the headlights. After turning on the headlights for 15 minutes, these water vapors will evaporate and will not stay in the headlights.
Fogging conditions inside the light housing:
①There is a temperature difference between the inside of the light housing and the inside of the light
②The air inside the light reaches a certain degree of humidity
The formation process of fog inside the light housing:
①After the light is turned on, the temperature inside the light rises, and the water vapor in the light material is released to form hot and humid air.
②The temperature of the light housing decreases due to the cold weather.
③As soon as the hot and humid air in the light touches the inside of the cooler light housing, the moisture will quickly condense into the fog on the inside of the light housing.

Causes of flooding of headlights:
One thing worth noting is that the water in the headlights is a severe problem because the water inflow is nothing more than because the lights are broken, and seepage or the airtightness of the headlights is not good. If it is not repaired for a long time, It will affect the use of the headlights and even directly cause the headlight bulbs to burn out. The treatment method can be solved according to the degree of damage to the headlight assembly. If the headlight shell is seriously broken, the headlight assembly should be replaced without hesitation.

How to distinguish between water ingress and fogging?
Under normal circumstances, many people are not very clear on distinguishing whether the headlight is water or foggy and often think that it is water when they see water droplets. There is a way to determine whether the headlights are flooded or fogged, and that is to check the traces of water flow.
We know that if water enters the headlights, it usually enters from above the headlights and then flows under the headlights, which will form obvious traces of water flow, similar to a waterfall. Even if the water is dry, there will be some traces; just like a snail’s path, there will be traces.
If you see that the headlights only form water vapor below and the tops are still immaculate, it is generally a typical situation of fogging. It is better to put some desiccant in it, turn on the headlights, and dry the inside by turning on the lights. The water vapor usually dissipates in about a week.

How to deal with foggy headlights?
Usually, when there is fog, as long as you use the headlights normally, they will completely dissipate in about a week. If it is particularly serious, you can open the back cover of the waterproof cover of the headlights, turn on the headlights, and let the xenon lights dry the fog inside. And then cover the waterproof cover after cooling, and it will be fine.
How to solve the water in the headlights?
Find the air leak, seal it with glue, or re-seal it. If the air outlet is blocked, you need to open it. If it is not enough, you can open another air outlet. The air outlet must be sponged, preferably a curved air outlet.

Reminder
It is recommended that all car owners regularly check the lights in the winter and rainy seasons. For example, it is necessary to check the vehicle after wading. Early detection and early remediation, and timely elimination of faults in the budding stage, are the best choices for car maintenance.
