Problem classification: Mild?

Car owner: GrumpyManUK, obvious location 

This is the first report we have from the UK, where the Model 3 recently started its sales.

Tesla is telling customers there that condensation is normal in all vehicles because lighting elements are semi-sealed. When they are lit, they would generate the necessary heat to end the condensation. Will that degrade the taillight? Will it interfere with lighting? We cannot say for sure. Some users at the Tesla Motor Club thread think GrumpyManUK should get that fixed as soon as possible.
