BULB REPLACEMENT

Lamp assembly condensation
Exterior lamps are vented to accommodate normal changes in pressure.
Condensation can be a natural by-product of this design. When moist air
enters the lamp assembly through the vents, there is a possibility that
condensation can occur when the temperature is cold. When normal
condensation occurs, a thin film of mist can form on the interior of the
lens. The thin mist eventually clears and exits through the vents during
normal operation. Clearing time may take as long as 48 hours under dry
weather conditions.
Examples of acceptable condensation are:
• Presence of thin mist (no streaks, drip marks or droplets)
• Fine mist covers less than 50% of the lens
Examples of unacceptable moisture (usually caused by a lamp water
leak) are:
• Water puddle inside the lamp
• Large water droplets, drip marks or streaks present on the interior of
the lens
Take your vehicle to a dealer for service if any of the above conditions of
unacceptable moisture are present.
