Is It Normal for Fogging in MG HS Headlights?
1 Answers
Fogging in MG HS headlights is normal. The main reasons for this are: 1. Recent heavy rainfall. 2. High moisture content in the air, which enters the headlight and condenses on the lens. If this occurs, you can wait a few days for it to disappear naturally if you're not in a hurry. If you need it gone quickly, you can use a hairdryer on medium heat to blow it away, and the fogging will disappear. Headlights are not completely sealed from the outside because when the lights are on, the internal temperature rises significantly, requiring ventilation to release heat. After turning off the lights, air needs to enter to balance the internal and external pressure. This necessitates ventilation ports in the headlights, which are designed to balance airflow and sealing performance to prevent water ingress. If water enters the headlight, it indicates a sealing issue and is a quality problem.
