Foggy, dirty car headlights make driving at night an iffy proposition. Decreased vision is a recipe for night-driving danger. If the water and other debris is allowed to sit, it can cause the bulbs to burn out. . Thinking about that fixing fogged car headlights is an easy procedure, you will have no one to blame but yourself if things go sour.
What happened on the headlights?
Water enters to the headlight assembly of any automobile, writes Popular Mechanics. If you live in an area that experiences cooler temperatures, your car is going to get wet. The same design points that allow air flow to cut back pressure on the plastic cover all let moist air in. Typically this is not an issue, however; the morning sun burns off the moisture. But if it does not – let’s say your auto is parked in a shady spot or parking structure – some action may be necessary.
Some tips about what you do with foggy car headlights
If you are a fancy lad, have your butler activate the headlamp defogging laser. If you aren’t fancy, do it like the rest of humanity.
Popular Mechanics says you should discover out if a Technical Service Bulletin exists for the model and make of your vehicle. That bulletin will reveal whether there is an upgrade available to replace the factory headlight housing (which is usually cheap and inefficient at venting the lighting unit).
If there is no upgrade to pursue, get down to DIY basics. If there’s only a small amount of condensation inside the headlight fixture, leave the headlights on when you drive for a couple of hours. It’s a great excuse to take the scenic route. However what if the headlamp’s a gusher? Then you have to take out the fixture. Clean up, taking care to exterminate any mud deposits or bugs present within the fixture. Dump the water and critters, add some rubbing alcohol to the housing to clean the surfaces, then let the whole thing dry for a couple of hours in the sun before re-insertion. Last however not least, park your automobile facing south from now on for maximum sun exposure within the northern hemisphere, says Popular Mechanics.
