Here are the methods to deal with water in car headlights: 1. Remove the headlight assembly and separate the lens from the housing. 2. Use a hair dryer to dry out the moisture. 3. Reinstall the lens and seal the edges with silicone sealant, then reinstall the bulbs. Below are additional methods to handle water in headlights: 1. Turn on the high beams for 10 minutes, then turn them off and wait for 60 minutes for the fog to naturally dissipate. The principle is that the heat generated by the headlights will directly evaporate the moisture. 2. Remove the headlight lens, dry it with a cloth, and then reseal the lens.
I used to encounter the issue of headlight water ingress quite often and have handled it myself several times. The first step is to disconnect the power to prevent any short circuits caused by water. Then, remove the bulb and the headlight cover, gently pour out the accumulated water, and wipe the interior dry with a clean cloth. If there are residual water droplets, I usually leave it in the sun for a few hours or use a hairdryer on low heat to dry it. It's crucial to check if the sealing ring has aged or is damaged—if found, replace it with a new one. After the treatment, test if the lights function normally. For prevention, avoid directly spraying high-pressure water at the headlights when washing the car and regularly clean the edges to prevent dust buildup. This DIY approach saves money and is quite fun, but if there's a significant amount of water ingress or severe damage to the seals, it's better to visit a professional shop to avoid flickering lights that could affect safe driving, especially since headlights are essential for nighttime visibility.
