Yup, that's what happens when I open my trunk lid; water streams out of the backup light housing. I will remove the light assembly and inspect the gasket/mating surface this weekend. I have the 3M material sitting in my toolbox. I figured I had the infamous leaky trunk syndrome, but I was not sure from reading previous posts and repair solutions.
Thanks for defining my problem.
