Moisture in headlights

Anyone have a problem with moisture in the headlights??? I have a 2010 Grand Sport and both headlight housings have visable moisture inside.

With all the rain we had, isn't everyone here in Metro Atlanta having a moisture problem?
Seriously though, I don't have a C6 so I can't be sure but moisture in the headlight housing must be a defect either in manufacture or build wouldn't you think?

The headlights are vented and sometimes moisture gets inside when you wash the car or drive in the rain, this is normal. Turning your headlights on burns it away.

I believe Ugolino is correct. I remember seeing that explanation on the DVD that came with my 2006.

I've been getting it too with all of the high humidity here in Georgia.
Owners manual/dvd says its pretty normal. Run the lights for a while and it is supposed to go away.

Look like crap though!

Not your car of course...it is a true beauty!

There are air gaps around both high & low beam lamps. If you have moisture (usually humidity condensing on the underside of the lens.)
Here's what you can do~
1. You'll need to remove the access plug on the rear of the housing.
2. Blow inert gas (nitrogen) into the housing via hose.
3. Re-install the access plug with silicone grease (making it air tight.)

For insurance, you can use some silica gel sachets before you install access plugs. Don't ask me where to put them as this is overkill for me.

Blowing dry nitrogen into the housing will replace the wet air that is causing the condensation problem.
