Use your Honda vehicle for long enough, and you will start to notice condensation building up within the headlights. This is a normal process that affects every single vehicle on the road, but can impair visibility by reducing the amount of light the headlamps are able to shine onto the road. Luckily, with a bit of knowledge and some simple preventative techniques, you can reduce this condensation or fog and ensure you maintain perfect visibility while driving.
Why They Fog
The headlights on your Honda will fog up when there is moisture inside of them, and this can be difficult to avoid. When the temperature drops, your headlamps will cool down after being used. When this happens, the cool air from outside enters the housings, and this air also happens to be moisture. All headlight housings have vents along the bottom and top to account for pressure differences as this prevents them from cracking and failing. Anytime the clear lens made of plastic is slightly cooler than the air within the housing, moisture droplets begin condensing along the interior of the lens. This moisture evaporates automatically in the morning when the outside temperature rises again. Depending on where you park your car, your Honda’s headlights may have more moisture than normal. This is particularly likely if you use an underground parking structure that is damp and cool or a shady damp area under a tree. In extreme cases, moisture can even pool within the housing for the headlights.

Preventing the Fog
You can find numerous options for preventing this moisture accumulation in your Honda’s headlights. In some cases, simply leaving your headlights on during a several-hour-long drive will be enough to get rid of the moisture. In other cases, you may need to dry out the area by removing the housing. Take care and make sure you understand what you are doing if you choose to use this method.
