Turn on the headlights directly when there is water mist inside. After the headlights have been on for a while, the areas directly exposed to the light on the lens will dry quickly, while the mist at the edges will take longer to evaporate. This is because the area directly exposed to light is limited, and the temperature gradually increases from the center outward, making the evaporation of moisture at the edges of the lens slower. Here is more information about water mist in headlights: 1. Water mist in headlights is actually caused by the structure of the headlight and air circulation. 2. Inspect the headlight by visually checking whether components such as the lens, vent cap, plug, and bulb holder are in the correct position and whether there are cracks or other damage.

I also encountered the problem of foggy headlights while driving before, and the blurry lights were particularly unsafe while driving. This is usually caused by aging seals on the lamp covers or large temperature differences, just like when you turn on the air conditioning in the car during summer, and condensation forms inside due to the heat outside. A simple solution is to turn on the headlights for about half an hour to let them dry naturally. If the fogging is minor, it usually disappears on its own. However, if it happens repeatedly or there are a lot of water droplets, you should check if the seals on the lamp covers are cracked or damaged. You might need to visit a repair shop to replace the seal. Don’t rush to dismantle the lights yourself, as you might end up letting in more water. When parking, try to avoid direct sunlight or humid areas. During regular maintenance, ask the mechanic to take a quick look at the headlights—this can prevent a lot of trouble. Safety comes first; driving at night with unclear headlights can be dangerous. It’s always right to address the issue promptly.

Having driven for decades at my age, I've seen headlights fog up countless times. It's mainly due to poor sealing, especially in older cars which are more prone to this issue. I remember once during a long trip when my headlights got foggy—I simply turned on the high beams and drove at high speed for a while, letting the hot air dry them out, which worked quite well. But for a long-term solution, you need to check if the headlight cover interface has loosened or if the sealant has aged. Clean it thoroughly and try pressing it back tightly. If there's heavy condensation, don't force it, as it can easily burn out the bulbs. For prevention, avoid blasting the headlights with high-pressure water jets when washing the car, and park in dry, sheltered spots. Honestly, it's not a big deal—as long as the lights aren't completely out, it doesn't affect driving, and handling it yourself saves hassle and money. Over time, I've learned that regular checks on the seals are more important than anything, especially during winter when temperature fluctuations are significant.

Dealing with foggy headlights is quite simple. First, check the extent of the fogging. For mild cases, try turning on the high beams for about ten minutes to let the heat dry them out. If there's a lot of moisture and it doesn't dissipate, inspect the seal around the headlight cover for any damage or looseness. Cleaning the gaps yourself might help. If that doesn't work, consider replacing the sealing ring. Don't rush to spend a lot of money—sometimes just parking in a well-ventilated area to let it evaporate naturally can solve the problem. Remember not to disassemble the headlight, as it might make things worse. This issue doesn't significantly affect brightness, but for safety's sake, it's best to fix it when needed—it doesn't take much effort.
