WHY ARE MY HEADLIGHTS HAZY, CLOUDY, OR YELLOW?
You clean and keep your car in tip-top shape, but can’t help noticing that your headlights are becoming fogged up despite your best efforts to keep them clean. So, why do headlights become hazy, cloudy or yellowed even with regular cleaning?
In the days of yesteryear headlights were made of glass…those days are long gone. They are now made of hard plastics, known as polycarbonate, that are specifically strengthened for the job. It is very strong, but it also is naturally porous so to combat this, the headlight manufacturers cover them with a protective film that may work well for a few years, but then starts to breakdown. Considering that headlights are exposed to heat from the bulb, UV rays from constant exposure to the sun and harsh chemicals that come up off the road, it probably should not be a surprise that the film eventually fades. Regardless, this allows the plastic to become oxidized, which gives the headlights the foggy look.
Most people believe the foggy headlight is a problem simply because it looks bad. While this is definitely true, there are also safety issues to consider. The oxidation of the plastic headlights cause the light output from the internal bulbs to be diffused. This effectively means that the beam from each headlight is diminished, and produces a reduced area of coverage.
