CONDITION SUMMARY

Situation:  The tail lamps may exhibit condensation or 'misting' which will not easily clear.

Cause:  This may be caused by the design of the tail lamp assembly allowing moisture to settle on the inside of the lamp lens.

NOTE: Normal condensation is a natural process. Range Rover tail lamp assemblies are vented to alleviate changes in pressure through a breather vent. Atmospheric air contains water vapor referred to as humidity. When this air enters the tail lamp assembly under any circumstance, there is a possibility that if the temperature is cold enough that condensation may occur. When normal condensation occurs, a thin film of mist can form on the inside surface of the plastic lens. The thin mist will clear and exit through the vents during normal lamp operation.
NOTE: During a period of normal tail and fog lamp operation (approximately 30 minutes), the condensation should dissipate as the lamp heats up. However, if considerable water droplets still remain on the inside of the lamp lens after the 30 minutes of operation or there is evidence of standing water within the lamp assembly, the lamp assembly should be renewed.

Action:  Should a customer express this concern, follow the Service Instruction outlined below.
