The small square below the car's headlights is the headlight cleaning device, used to clean dust from the surface of the headlights. There are two structural modes for the headlight cleaning device. Scrubbing system: Used for glass diffusers, because although plastic diffusers have wear-resistant coatings, they are still relatively sensitive to mechanical cleaning. This type of cleaning system can still be seen in older generation models. High-pressure cleaning system: Used on both glass and plastic diffusers. The cleaning effect mainly depends on the distance between the nozzle and the diffuser, the size of the water droplets, the contact angle, the speed of the water spray, and the amount of water sprayed.
