Well the first attempt at sealing the lens failed. So I removed it again from the car this time it had a good 4 cups of water inside. Here is what I did. In an attempt to dry out the inner housing I used some compressed air that didn't work so next was a hair dryer on low heat setting. I did this back and forth through the bulb openings for about a minute. No real change in the moisture in the housing, the biggest change was the red outter lens came off giving me the ability to take apart the entire housing and hand dry everything. A few interesting finds you will never get the water out of these unless you take them apart there are to may layers of plastic and compartments. 2nd the parking light is 2 very small leds on a circuit board. There are 2 of these boards on either end of a reflective lens. Now onto the repair. I was able to clean all the corrosion from the led circuit boards with a very fine brass bristle pen and a electronics contact cleaner called Deoxit not cheap but worth its weight in gold. Don't use anything but a soft very clean lint free cloth to dry the lenses or you will scratch them severely. Everything has to be completely dry if its not once you seal it back up and the temperature/humidity changes you will get condensation. Once I was happy with everything being dry I prepared the outer housing using my wire pen I carefully went around the seam to remove the failed factory adhesive and wiped everything down with alcohol wipes until it was clean. To rebond the lens I used super 6000 glue it stays flexible bonds great and unlike a super glue will not off gas and discolor clear plastic
