Can the Headlight Vent Be Blocked?

[PaisleyFitz]

No, it cannot be blocked. The headlight vent is a properly designed component that maintains the air pressure balance inside and outside the headlight, preventing damage caused by excessive internal pressure. It also helps extend the headlight's lifespan. The function of the headlight vent: In terms of the overall structure of the headlight, whether it's a standard halogen headlight, a xenon headlight, or an LED headlight, there is a venting rubber tube located at the rear cover. When the headlight is turned on or during use, it generates a significant amount of heat. The vent tube helps dissipate this heat as much as possible to maintain the headlight's normal operating temperature and ensure stable performance. Disadvantages of the vent: Moisture in the air can enter the headlight through the vent and condense on the lens. As moisture accumulates, water droplets may form and flow down the lens.
