The heat dissipation vent of the Audi A3 headlight is located at the rear of the headlight. When the humidity is high and there is a significant temperature difference between the inside and outside of the headlight, a small amount of fog may form on the inner wall of the headlight cover, which usually disappears automatically after the headlight has been on for a while. The function of the headlight heat dissipation vent: In terms of the overall structure of the headlight, whether it is a conventional halogen headlight, a xenon headlight, or a headlight with LED light groups, there is a ventilation rubber tube at the position of the rear cover.
