I had to seal around my lights too. I also noticed that there are sealing washers in the light bulb sockets. One of mine was torn and mega moisture was getting in there.
I replaced all the bulbs at once, to ensure they were all new.
It is all fixed up now, have not had any problems since using a marine polyurethane sealant.
I,t hadn't occurred to me until you and John1 mentioned changing lamps, but I have never replaced a tail light on this car in the 13 years and 257,000 mi I've
had it. In fact, I can only remember changing 1 headlight. I wish GM made gaskets and power window regulators that good.
