How to Make Your Headlights Shine Like New

Most headlights are made of polycarbonate plastic, which is durable and scratch-resistant. But over time polycarbonate clouds over, mostly due to UV rays that degrade the outer layer of plastic. Fortunately, there are plenty of products on the market designed to help you restore your car’s 20/20 nighttime vision. Here’s how to clean your headlights so they shine like new.

Most cars and a lot of trucks today are manufactured with headlamp assemblies that use quartz-halogen bulbs plugged into the back of a large plastic reflector. The outer surface of these headlamp modules is molded polycarbonate plastic. That plastic is much lighter than glass and far more resistant to stone chips and cracks. However, after a few years of exposure to sunlight and atmospheric chemicals, polycarbonate has a tendency to get hazy. Severely neglected lenses can actually pit and develop a network of fine cracks, called craze, which makes the job of fixing them tougher. It’s worth a shot, though—and you’ll need only a few bucks’ worth of materials to get the job done. Sure, these assemblies are easy to replace, but they can be very expensive. A pair of lenses for a luxury car can cost as much as a thousand dollars. Woof.
