My left tail light was replaced - under warranty - because it would fill with water.
Of course it is now out of warranty and the replacement fills up, too.
For the life of me I can't figure out how it is entering the light.
I am inclined towards thinking it is condensation and that I should drill a small hole in the bottom to allow the water to escape. If so, why don't I have the same problem of the passenger's side tail light?
