Water in headlight

[NDA]

One of my cars has a completely sealed headlight unit which has condensation in it - a lot, not a misting, but water droplets... all over the inside of the glass.

I would imagine it's a case of replacing the costly unit - I am not a DIY'er so don't have the skills to take the front of the car to bits.

Unless there's a hairdryer type fix? I've no idea.

If you could remove a bulb and leave it facing the sun to dry out (I know I know) it could buy you some respite from the problem for the summer at least.

If you remove the bulb and holders you might get away with using a hairdryer through the holes, you'll need a bit of patience because if its water rather than condensation it often takes a while to dry out completely, you might also be able to feed a paper towel through the hole to soak it up, just don't let it rip inside!!.

You could also help it along with one of these.

It can’t be completely sealed or it wouldn’t be full of water
There’s always a fix.

Sunny day.
Remove as many bulbs as you can and leave holes open.
Face car into sun.
Wait for nature to do it's thing.
End of day, before it cools, pop bulbs back in.

Share what car it is, I expect it has been fixed before.

I had a TT mk1 that did this.. it looked 100% sealed but it had a tiny crack in the plastic…sealed that after a dry out and that sorted it

And wait for the next wash for them to let water in again sadly

I had this probelm with an F10 5 series years ago - replacement lights needed.
