Exterior Lights, Moisture Accumulation
Condensation and or water droplets visible on inside of exterior light lenses.
TECHNICAL BACKGROUND
Exterior light assemblies (headlights, taillights, fog lights, turn signals) are vented
and may collect moisture on their inner surfaces, depending on humidity and climatic

more common with modern exterior lights because of clear glass optics, however this
condition will not have an impact on the functionality or durability of the component.
