What is the problem with
those yellow foggy headlights?
Polycarbonate plastic is
used because of its tensile strength and the ability to be
manufactured to conform to the front end styling of a
vehicle. Although it's a very hard plastic, it's also very
porous so during manufacturing a protective silicone hard coat
is applied to the headlight lens. This silicone hard coat is
supposed to protect the headlight lens from intense sun, heat,
road chemicals, bugs, humidity and acid rain, etc.
But these elements,
combined with the heat of the halogen bulb damages the
protective hard coat to the point that a ugly discolored,
cloudy, hazy appearance develops on the lenses. This damage
will restrict the headlights ability to project its beam of
light at night, and during adverse weather conditions, may
diminish the ability to see by as much as 70%.
When you account for
how much better your vehicle will look, the increased resale
value, and taking care of a dangerous safety issue, why would
you do anything but get the problem fixed immediately.
