FRONT LAMP UNIT 

STANDARD PROCEDURE 

FRONT LAMP MOISTURE CLEARING 

Some occasional moisture accumulation inside a vented front lamp unit is normal and appears as a fogging on 
the inside of the lamp lens, similar to the fog that sometimes appears on the inside of a windshield. This 
condition is caused by rapidly changing temperature and humidity levels between the air internal and external to 
the lamp, and will usually dissipate once the temperature and humidity conditions have been allowed to 
stabilize. Accelerated removal of such moisture may be accomplished by activating the headlamps on HIGH 
beam for about 15 minutes. 

However, water droplets larger than 1 millimeter (0.039 inch) in size accumulated on the inside of the lamp 
lens, water droplets visible on most internal lamp surfaces or large quantities of water within the lamp indicates 
a problem with the lamp sealing that has allowed excessive amounts of water to enter the lamp. Once such 
excessive moisture has entered the lamp, it will always be present and will never disappear. A lamp with 
permanent internal moisture should be replaced.
