you’ll discover that the haze is on the outside of the headlight cover, and is caused by environmental factors. Ultraviolet light from the sun is the leading culprit, followed by road salt and grime that interact with the plastic and cause it to lose its transparency.
Headlights that fade over time are impossible to avoid, as it’s a part of how the components wear out, but it’s essential that you do something about it. By replacing the bulbs, installing new headlight lenses or getting new bulbs, you can ensure you’ll have a clear view of the road ahead.
Some headlights are part of an entire assembly, so you can’t simply change the bulb. If you need to replace the entire headlight assembly, it shouldn’t take long with most car models. If the job is straightforward, you are looking at less than an hour. However, your model might require that the entire front-bumper fascia be removed—or at least loosened—to reach the headlight assembly. For example, replacing the headlight on a Toyota Camry, Chevy Malibu, or Ford Fusion might be more challenging. It requires extra time, so give yourself at least two hours if you aren’t experienced.
Before you start, we recommend two things:
These will help you understand the specific steps required for your model. Here are essential pointers for swapping headlight assemblies.
Remember also to check the aim of the headlights using our guide to adjusting headlights.
Moisture in Headlights
Usually, when you turn the headlights on, the heat causes the moisture to evaporate. It can also evaporate on its own over the course of the day, as the sun warms things up enough to do the same job. Driving the car can also help, as it allows air to pass through the vents in the light housing and clear out the moisture, much like running the defroster in your car’s cabin clears the windshield.
Since most headlights generate heat, they need to be ventilated, which means that they feature small vents that can suck in moisture when the car is turned off. If the outer lens cools more quickly than the air inside the headlight unit, it can cause condensation. This explains why you most often encounter condensation in the morning after your car has been parked overnight.
Moisture in headlights can be a frustrating problem:
If you’re seeing more than a normal amount of moisture in your headlights, or if you’ve noticed more water inside the housing after a rain storm, you could be dealing with a cracked headlight or a problem with the rubber gaskets that seal it to the body. Most of the time, gaskets can be replaced individually, but if the headlight housing is cracked, then you’ll most likely have to replace the entire unit.
Prevent Further Moisture:
There’s a number of products that can help you recreate a firm seal.
