I have to take a look at these, but there is a route to go.
The HIDs on my STi, you can "bake" your headlights. Stick them in the oven for 10 min @ 200 degrees, and you can pull the headlights apart. Be careful, DO NOT touch anything on the inside, yet remove the reflector. Buy some silicon sealant, reseal the headlights back together, bake again, then reinstall.
I had no problems with mine for 4 years and never got any moisture inside even living up in the Pacific NW.
Of course, I don't know if I want to be the first to try that method with these headlights.
