Water in my drivers side tail light

So 2 or 3 days ago I noticed there was a good bit of water/condensation in my drivers side tail light. I know that dealerships are likely to say oh it should go away if its not too bad, but its still there 3 days later so I doubt its going away on its own. Has anyone else on here had any issues with moisture getting in the lights?



This is what it looks like







Think dealerships are open on New Years? I'll have to schedule an appointment for it to get checked out as soon as I can get in touch with them.
