Water in rear tail light

[Mansderm161]

I get water in rear drivers tail light with rain. From the outside, everything looks good and aligned. This has also caused some erosion, because I can see rusty water inside when it's wet. The water evaporates when dry, so there's a gap somewhere. Any suggestions? Heading to Airstream...want to make sure they correct and repair and don't want a back and forth between Mercedes and Airstream.

Ive heard that some people will drill a small hole at the bottom of the tail light for water drainage.

Cracked taillight or bad seal somewhere... that is all Mercedes, not Airstream.

Yep...especially with LED's,(no heat to rid the H2o).
The main reason all "Cloudsplitters" teardrops are still incandescent with a hole.👍
