NORMAL FOGGING / CONDENSATION
This bulletin provides information regarding
headlights that may experience fogging or
condensation inside of the headlamp
assembly. A drop in air temperature may
cause condensation to form on the inside of
a cool headlamp lens. Generally, fogging is
considered normal and can be eliminated by
turning on the headlamp with the engine
running for several minutes. In most cases,
operating the vehicle in normal driving
condition will clear the headlamp fogging.
Headlamp assembly replacement WILL NOT
be necessary in most cases.
NOTE
If any of the following conditions occur,
please consult with a professional
mechanic to determine the water source:
If condensation/fogging fails to
dissipate a er operating the headlight
with the engine running for 30 minutes
If water pooled inside the headlamp
A high pressure washer may also cause
water to be forced into the
headlamp assembly.
Light has non functional dummy plug bulb
holder. Please leave this installed to prevent
dust and moisture from entering the light.
