I believe the issue is with the 09-18 models. I haven't had a problem yet with my 14. The lights have a screw at each end but the center does not. The housing has some flex to it so it doesn't push up tight to the body. At least that's what it looked like to me when I took mine out to change the bulb.
My 05 Daytona leaks water thru the 3rd brake lite,so the problem is earlier than 09.After Googling this it seems that this is a real common problem with these trucks.
