This will usually clear as atmospheric conditions change to allow the condensation to change back into avapor. Turning the tail lamps on will usually accelerate this process.Clear Tail Lamp AssemblyTail Lamp Assembly with CondensationImages are not specific to vehicle, and only used for showing the tail lamps either clearFig. 1or having a condensation build up within the tail lamp assemblyFig. 2per the procedure.
