GX470 2008 Backup Reverse light Water Condensation

Dealership replaced both backup reverse lights (complete assembly) as they were getting water condensation. Right side is ok but left side still get water condensation. Lexus Dealership have replaced left side 4 times now with new assembly , and also have checked all the seals.

Now they have ordered new seal which goes inside the back door, lets see if that fixes the issue.

Did anyone have this issue with GX470 reverse lights 2008 . Thanks!!
