Seems like my earlier post isn't being read.
They have a new part that does not have the plastic windows. It is what is being shipped on all new Teslas. They will put it on as part of warranty if you have condensation. This isn't a "fix", this is a totally new part that solves the problem.
Thanks for the heads-up. I have had that very moisture issue in the rear lights since day 1 but keep forgetting to mention it since it has rained so infrequently this year. I do notice it a few hours after hand washing sometimes, which is a bit odd since I wash (foam and rinse) the entire car with a total of 3 gallons of water. Guess it doesn't take much.
