The glue used to join the clear and white plastic section of the lens (front and back, respectively) is of very poor quality. The glue comes apart with time and if you use a screwdriver you can actually separate the lights very easily, this is why water can get it and cause moisture.
You will have to go to a local auto shop and buy black or grey gasket maker, it comes in a silicone like caulk tube.
With a flathead, pry the lights apart around the merging point, if they are old they will come apart really easily. Clean the seam path and apply new glue in the tracks, it should be about 1/8" of glue in the channel.
You can now press the two pieces together and let them dry for 24 hours to fully cure inside the house. Make sure the bulbs are removed so the glue can dry properly or else it will smoke when turned on.
