CONDITION SUMMARY:
Situation: Condensation/mist may appear on the inside of front and/or rear exterior lamps.
Cause: Condensation/mist is a natural phenomenon which can occur when there is a temperature difference between the inside an
of the lamp unit. This condensation is considered to be as a result of normal atmospheric conditions and replacing the light unit will
correct this symptom. With the introduction of clear lenses condensation is likely to be more noticeable but does not affect the
of the lamp. Condensation will clear when the lights have been on for some length of time and in warmer ambient temperatures.

Action: A lamp that exhibits condensation should be evaluated after a drying time where all the functions have been operated for a
minimum of 30 minutes. If the condensation has started to clear during this time, it indicates that the lamp sealing has NOT been b
and will eventually clear. The lamp must NOT be replaced.
SERVICE INFORMATION:
CAUTION: make sure that bulb covers are correctly installed and make sure that all breathers (tubes or membrane pa
are free from dirt and debris and are fitted correctly as these can all lead to the formation of condensation. If any of these
determined to be the cause of the condensation, measures should be taken to dry out the lamps and to make sure that the
covers are installed correctly.
NOTE: the Owner's Handbook clearly states that condensation may form on the inside of lamp lenses and is caused b
atmospheric conditions. That it is not detrimental to lamp performance and will clear during normal usage.
NOTE: pools of water and high levels of condensation would indicate that the lamps sealing has been compromised. C
for damage and inspect the condition of caps and breathers.
NOTE: differing layout on the opposing sides of the vehicle can lead to different levels of condensation inside the lam
side to side. As a result of this the rate at which condensation clears may also differ from side to side.
NOTE: photographic evidence of the condensation levels prior to and after drying time should be provided with every
returned part. Failure to do so may result in the claim being rejected.
NOTE: this information bulletin contains examples of normal condensation generated from atmospheric conditions. A
mist can form on the interior of clear plastic lenses, this is not detrimental to the lamp's performance. This thin mist will
eventually clear through normal use, exiting through the lamp's venting system.
1. Condensation or moisture can be more noticeable during the months of spring and autumn when there is a likelihood of a higher m
content in the air. It can occur when there is a temperature difference on either side of the lens surface. This can often be seen
in the evening and morning sunshine or when cold water makes contact with a warm lamp lens. When a lamp is warmed unevenly
sunshine the surface area in direct sunlight will be approximately 10°C higher than the remainder of the lamp. When warm air circu
within the lamp and makes contact with the colder surfaces moisture can appear on the lens as water condenses out of the warmer
Condensation may occur when washing a vehicle with cold water on a warm day or when the lamps are warm and vice
same phenomena as with the formation of dew on the surface of a glass window pane.

These are examples of normal exterior lamp condensation. This would NOT be covered by Warranty and the lamp should n
replaced.

providing the lamp does not exhibit any visible signs of external damage.
