I recently installed a set of Valenti tail lights and I didn't want to have to deal with the condensation issue or the water inside the tail light issue a lot of people have been having. So I used weatherproof adhesive to attach the gasket to the tail light backing and used weatherproof tape to seal the gaps on top of the tail light (instructions from GasketNinja).
I went to test whether everything was working okay and properly sealed... and I'm hearing a water dripping sound inside of the rear bumper possibly? Has anyone else experienced this? Is this a normal occurrence? Haven't really noticed it before when I had OEM tail lights.

I tried to get the phone as close as possible to allow the sound to be recorded. This happens on both sides of the tail lights as a note.
