If you have cloudy and yellow headlights you are taking a big an unnecessary risk when you drive at night. According to the AAA Foundation For Traffic Safety an average of 9 out of every ten cars on the road today has dirty or yellowed headlights that greatly reduce vision and need to be repaired, restored, or replaced.
Most people do not know that not only do worn or cloudy headlights look bad, but they also reduce light output by as much as 95 percent. That is a huge difference in whether you can effectively see or be seen when driving at night.
It was found that thousands of accidents were linked to ineffective light output due to worn and cloudy headlights. The majority of headlight lenses produced today are made of plastic and are very susceptible to road and weather conditions. Harsh UV Rays in hot climates, chemicals from the engine and fumes, smog, bugs and more, all take a toll on the plastic lenses and cause them to breakdown from the outside in. The resulting cloudiness is like a disease and quickly gets worse and will soon reduce visibility and make your vehicle unsafe at night.
Accidents caused by reduced light output and bad/cloudy headlights tend to also be much more severe. According to the National Institute of Highway safety, accidents at night due to a more limited visibility usually of a more severe nature.
