Why is there water inside the headlight cover?

[DelGeorge]

This is generally caused by poor sealing of the headlight. Here is some relevant information: 1. Car lights: The front lights of a car include low beams, high beams, daytime running lights, fog lights, warning lights, and turn signals. The headlight usually refers to the high beam, which is mainly used for illumination during nighttime or in weather conditions such as heavy fog or rain when lighting is required. 2. Function of car lights: Car headlights are like the eyes of a person and are closely related to safe driving. Simply put, car headlights serve two purposes: one is to provide illumination for the driver, lighting up the road ahead, ensuring good visibility during bad weather or at night; the other is to serve as a warning, alerting vehicles and pedestrians ahead. Car headlights, also known as front lighting lights, include halogen lights, xenon lights, LED lights, and laser lights. The most common types of car headlights are halogen and LED lights.
