Headlamp Assembly

WARNING: This page is about a different car, the 2022 Ford Bronco Sport. However, it is still accessible from the selected car via links, so may be relevant.

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 if the temperature is cold. When normal condensation occurs, a thin mist forms on the interior of the lens. The thin mist eventually clears and exits through the vents during normal operation. The amount of time it takes to clear the lens of acceptable mist varies with ambient humidity and lamp types. Normal condensation clears from any lamp in 48 hours under dry conditions.

Do not replace a lamp assembly with acceptable levels of condensation such as:

presence of thin mist (no streaks, drip marks or droplets are present)
fine mist covers less than 50% of the lens

Examples of unacceptable moisture (usually caused by a lamp housing leak):

water puddling inside the lamp
large water droplets, drip marks or streaks present on the interior of the lens
