Hi all,

Both my fog lights have condensation, I have sealed them with silicon after drying them out again and again but it still returns.

I have seen on line where its recommended to drill a small hole but I am skeptical as there is a vent under the cap on the top of the fog light and both vents are unblocked.

Any advice would be appreciated, Thanks

Copied from the owners manual:

Condensation in Lamp Assemblies
Exterior lamps have vents to
accommodate normal changes in air
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
when the temperature is cold. When
normal condensation occurs, a fine mist
can form on the interior of the lens. The
fine mist eventually clears and exits
through the vents during normal operation.
Clearing time may take as long as 48 hours
under dry weather conditions.
Examples of acceptable condensation are:
• The presence of a fine mist (no streaks,
drip marks or large droplets).
• A fine mist covers less than 50% of the
lens.
Examples of unacceptable condensation
are:
• A water puddle inside the lamp.
• Streaks, drip marks or large droplets
present on the interior of the lens.
If you see any unacceptable condensation,
have your vehicle checked by an authorized
dealer.
 

Thanks for your reply Neil, as usual I would look for a remedy and read the manual later,  Cheers

No problem John, I'm usually like that myself but I remembered seeing it on one of the rare occasions I looked in the manual, I can't even remember what I was actually looking for now!
