It is normal to have small water droplets inside new headlights. Rubber vent tube: In all current vehicle models, whether they are halogen headlights, xenon headlights, or the more technologically advanced LED headlights, there is a rubber vent tube behind these lights. When the headlights are instantly ignited or during normal driving, the heat generated is expelled through this tube. However, precisely because of the existence of this tube, moisture from the air can "seize the opportunity" to enter the interior of the headlights. Over time, this moisture forms fog, which accumulates into small water droplets. Headlight fogging: Headlight fogging generally occurs more easily in southern regions, during winter, or in months with more rainfall. In winter, the temperature difference between the inside and outside of the headlights is too high, similar to the principle of fog forming on glasses when moving from a cold outdoor environment to a warm indoor one. Solution for fogging: Headlight fogging is a normal phenomenon and can only dissipate slowly through the headlight's own heat. The best approach is to avoid using methods that could damage the headlights, such as hair dryers, heat guns, or high-pressure water jets, as these can harm the headlights.
