First of all, please judge whether the internal problem of the car headlight is fog or water according to the shape of the water droplets appearing inside the car headlight.
The external performance of fog and water that exists inside of the headlight is different. We have two ways to distinguish the two: #
- Method 1: Preliminary, check the traces of the water flow.
Fogging is generally to form a membrane or dew on the surface of the lampshade of the headlight without any trace of water flow.
Water ingress is due to a large amount of water condensed into dew that flows from the top of the headlight to the bottom. In this way, a clear water flow trace will be formed, which is similar to a waterfall. Even the water dries, there will still be some traces, just like the road a snail pass on.
- Method 2: After the fog inside the car lights appears, it takes about 1 to 1.5 hours to eliminate the fog in the lighting state; In a static state, it takes about 24 to 36 hours in a dry environment with a humidity of <50% for fog be eliminated automatically, this phenomenon is fogging. However, when a large amount of fog condenses into water droplets on the inner wall of the lens and then accumulates inside the car lights, as the temperature rises for a long time use, the fog will adhere to the inner surface of the lens once again. This phenomenon is water ingress.
What should we do after judging whether the car headlights are fogging or water ingress? #
·If it is water ingress, please send pictures or videos to the customer service staff of the original sales store for after-sales.
·If the surface of the headlight is foggy, please continue to use it for ten days and observe again.
If the fog disappears after ten days, it’s normal. The fog caused the temperature difference between the new lamp and the local temperature after the new lamp left the warehouse.
If it does not disappear after ten days, or if the fog appears again after disappearing, it means it’s a sealing problem of the car lights. Please get in touch with the customer service staff of the purchase channel.
