Automotive lighting Vents allow rapid exchange of air in response to pressure changes and allow internal moisture to escape Brief introduction of the Automotive lighting vent plugLamps are exposed to varying climate, road and vehicle conditions that can impact performance. Water spray, humidity, automotive fluids, road debris, dust and dirt can degrade light performance creating aesthetic and safety concerns. Rapid decreases in temperature can cause a decrease in internal pressure, which can draw in contaminants, increase condensation and cause lamp failure.Pan Asian lighting vents with special construct have been proven use in lighting applications and are more durable than competitive solutions. It is used for head lamps, position-independent design reduces design complexity for faster, most cost-efficient product development .Vents can be placed using either manual or automatic methods. Predictable performance lowers testing costs and reliable performancePerformance in the harsh automotive environment is maintained for the life of the vehicle.Pan Asian Vent plug protect against the negative effects of pressure differentials caused by temperature changes. With their integrated Membrane, these vents allow an enclosure to equalize pressure quickly when subjected to changes in temperature and pressure. These vents also provide an effective barrier against harsh weather conditions (e.g., rain, snow, high winds), while allowing water vapor to exit quickly and reduce the likelihood of condensation on the lens.The microporous  ePTFE  Membrane have the flowing good performance :Waterproof and dustproof to IP69k ;Water /oil repellent ;moisture- and vapor-permeable ;chemically inert ;non-shedding ;UV-resistant ;temperature-resistant
