You have two options:
1) take the headlight out and dry it out using a hair drier. Simply blow it into the empty bulb socket and it will dry the light out. Then take some black silicone sealant and reseal the entire light (were the clear plastic and black plastic meet). This will work and its not that big of a pain...I had to do it with one of my black lights and it solved the problem.
2) Take out the bulb and squirt a little water into the headlight...enough that there is a little standing in the bottom. Then take it back to the dealer and they will replace it. I know this will work too...at least it did on my last Dodge. Its not really dishonest...its just placing emphasis on the existing problem.
