condensation in headlights

[stickboy]

does anybody know how to cure condensation behind the plastic cover on my e39 headlights. I have dried them but it still returns ?

Seems like it's a BMW nightmare, I had a '87 325i and now a '97 328i, both with the same problem. Y tryed to fix it with silicone glue, and naothing hapened. Now as every married man, I learned to live with the problem.

i did dry my old ones once, but it came back.
so i bought new lights w/ angel eyes and it
is no longer a problem...

maybe use this as an excuse to upgrade to
some european spec lights =]

I wonder what's the cause...?
I've never had the problem though.
