Thanks very much for the IPB. That will be very helpful.

I'm getting both condensation inside the lens overnight when the temperature drops below the dew point, and a greater amount of water intrusion when it rains.

The car is under two covers, and I even cut some plastic sheet to size to fit over the entire assembly from inside the engine compartment to the bottom of the lens outside, but water is still getting in.

It looks like the lens is an assembly with the glass bonded to the plastic frame that snaps to the main housing, which is what I figured, and my hunch is that this is the source of the leak, so I'll carefully inspect it for a leak and should be able to seal it up without removing the entire assembly, at least along the top.

I'll keep working on finding the leak source and keep you all informed. Since I need to drive it a few times per month, and it's the only car I have in service right now, if I decide I have to remove the housings for resealing I'll have to wait until I get another car in service so I'm not without transportation.
