Water had leaked into drivers side rear brake light so I ended up using some caulking to seal it up

Water leaking into both tail light housings. Passenger side is minor, driver's side fills about one third full with water and empties into trunk when trunk lid is opened. Probably just run a thin film of silicone caulking around tail light assembly, less cost and hassle than replacing gaskets.

Gasket at tail lights leaks terribly. The design channels most of the water from the back of the car into the trunk around the tail lights.
