For headlights, heavy fog often appears in rainy days or high-humidity environments, so the fog needs to be dispelled quickly.
Some headlights are connected directly to the atmosphere.
The negative pressure caused by the shutdown will cause water to flow outside, making the fog scene more severe and causing damage to the components in the lamp.
Car headlights equipped with Teflon waterproof and breathable membranes have good luminous performance even under extremely harsh road conditions and operate smoothly for a long time.
