The car headlight water spray cover is usually installed on the front headlight assembly and works in conjunction with the headlight cleaning system. Its main function is to protect the internal spray nozzle from external contaminants such as dust, mud, sand, and insect remains, ensuring that the cleaning solution can be accurately sprayed onto the lens surface. This maintains the headlight's light transmittance and ensures clear visibility during nighttime driving or adverse weather conditions, making it an important supplement to the vehicle's active safety system.

Common Faults and Their Impacts

• Fault Manifestations: Potential faults of the headlight washer cap may include inadequate sealing of the cap body leading to leakage of the washer fluid, aging of the spring mechanism causing the cap to fail to open or close normally, entry of impurities into the nozzle resulting in abnormal spray angle, and loosening of the cap body generating abnormal noise or vibration.
• Impacts: If the headlight washer cap malfunctions, it may lead to failure of the headlight washing system, thereby affecting the cleaning effectiveness of the headlights and reducing driving safety at night.
