Taillght Lenses Filling with Water

Both my taillight lenses on my 2008 Windsport have about an inch of water in the bottom.
I took them off and the only way to drain the water was to turn them upside down and it drained through what looks like a vent hole in the top.
I assume the vent hole is to allow air in to prevent condensation build up.
However, I believe this must be the source of the water getting in.
I dont want to plug the hole as this may cause issues.
So, does anyone have an idea on a solution to prevent the water from entering and still allow air circulation?

Install upside down from what they are now.
A small scupper valve
Plug top hole, drill bottom hole.
maybe the headlight fluid has leaked into the tailights because thor used wires too big.
Below is a link to most of my modifications either accomplished or pending.
