Will a damaged dust cover affect vehicle lighting?

A damaged dust cover may affect vehicle lighting. On the one hand, if the dust cover is damaged, impurities such as dust and water vapor can more easily enter the interior of the vehicle light. The accumulation of dust may make the light dim and affect the lighting effect. After water vapor enters, it may condense into water droplets inside the vehicle light, leading to light scattering and also reducing the brightness and clarity of the light. Moreover, being in a humid environment for a long time may also damage the internal circuits and bulbs of the vehicle light and further affect the normal operation of the vehicle lighting system. On the other hand, a damaged dust cover may destroy the sealing of the vehicle light and affect the light focusing effect. The originally well-designed vehicle light system relies on a sealed environment to achieve a specific lighting angle and range. After the dust cover is damaged, this sealing is destroyed and the lighting may become scattered and unable to achieve the best lighting effect.
