Third Brake Light Question

I just finished cleaning my TB and I noticed that the third brake light was loose. I opened up the rear glass window and noticed that one of the plastic screw retainers was broken. I also noticed that the third brake light did not have any gasket around the housing of the light. Can someone check their TB to see if a gasket is attached to the outside or rim of this third brake light. My TB is still under warranty and I want to order the parts a head of time so I can just bring it in to get installed and if a gasket is required I will also order it.




Thank you
