This is a one of the photos that I sent to FT86 SpeedFactory, which they then forwarded to Emotion USA.
Emotion USA is saying that the gasket is the failure. That I installed the tail light gasket to close to the edge.
If you look closely at the photo, you notice that the gasket is "keyed' to the tail light with the 4 screws that are used to mount the light to the car, but also keyed by the small hole in the center of the gasket. The light unit has a permanent spike that sticks out from the light and fits through that hole in the gasket.
There is not wiggle room, and the gasket was not crimped. Furthermore, the right tail light is exactly the same!
You can also see the indentation all the way around the gasket where it sat flush with the light unit.
