406 Front foglight removal

The NS front foglight on my company owned 406 is heavily misted up. It
doesn't appear to be broken so rather than have the dealer charge a huge
amount to (probably) replace the lamp, I'd like to remove it and dry it out.
I can remove the bottom fastenings OK, but it appears to be held at the top
somehow. What am I missing - how do I release the lamp?
Thanks, Rory.

 

It is held at the top by a Torx bolt, the same as the other two.
Getting it undone is not too bad, but putting it back is another
story. Loads of patience needed, And a pot of heavy grease to hold the
screw to the screwdriver!!!
Trouble is you're going to go through all that trouble to dry out the
unit, and it will mist up again. You could just take the bulb out and
use a hairdryer to dry it out in-situ. If you do take it out you need
to find where the moisture is coming from.

 

Thanks for this - it's pretty wet inside so I hoped it would be reasonably
obvious where the sealing has failed. If not then I'll just seal everywhere
and see how it goes!
