Another source is water can leak through the tail light gaskets. Usually simply removing the tail lights, clean the back of the lights and the mating surface of the car, and carefully reinstall and snug up the mounting nuts, and all is good. In rare cases, you might have to replace the gaskets. One has to be careful not to overtighten the nuts, being set in plastic, you can break the studs out of the light.
