The eagle eye style tails do not have that black plastic cover like the OEM M3 LED tails do. I can say from experience having them on my first bimmer ('99 323i) and now on my ZHP, I have not had any issues with them regarding moisture leaking into the car or in the tail lights themselves. The gasket that comes with them are thin and cheap....that's where the moisture is coming in from. They do not provide a good enough seal, which is why I used that weather strip I got from Home Depot. Overall, I'm satisfied with them and I love how they look with the Imola
