Hey everyone, just need to ask you all a question.
I was detailing my car when I came across this, was wondering if this is true for all our cars.
In this picture you notice the black plastic piece that sits on top of the rear tail lights? Do yours have that much room at the side and at the top? There is enough room for me to put my finger in there. Was just wondering if it should be flushed, or if not, why isn't it? I'm concerned leaves,etc. might get in that's all.

Thank you in advance.
