Or do what my maintanance Sgt. did to our grand prix patrol cars....he drilled a TINY hole in the lense and it let the condensation out...just a thought. Not sure if it would work for the wrx, but it worked on the grand prix...he drilled down at the bottom of the lense.
What I would recommend is something simple. Re-bake them, open them up and let them dry out in a "dry" area. Once you're certain theres no moisture to be had, re-bake them and re-seal them. This time, apply a bit of silicon to further seal them together.
I disagree. The humidity in your average oven will likely be lower than just about anywhere else. Putting them anywhere else to 'dry out' will not help anything.
Have they gone awhile without any condensation? If this is the case, if the condensation got in, the condensation can get out. I've noticed one of my baked lights gets a little bit maybe once every few months. Usually it seems just turning my headlights on vaporizes it though and then I don't have to worry about it for along time.
