tail light full of water

[EZM]

Noticed when looking at the lens that my tailight was filled about 1/3 full of water. 2017 Ford F150.

Strange, since the only source of significant water would have been a car wash I did about a week ago.

Never had this happen before.

So, using a tiny drill bit, I drilled out one hole for air and second for water (at the bottom of the plastic lens housing - couldn't believe that water that came out - it was a tiny garden hose spraying out a couple feet - maybe a liter of water there.

Anyone ever have this happen before?

I think I'm going to leave the holes there, because I'm not sure where it's coming from, and at least it will drain. Not sure if that a good idea or not, bit the lights work fine.

The entire back up light was submerged (the clear white bottom part) and it still works.

If it continues to work, there is no need to replace the probably $200+ tail light assembly is there?
