Yeah, it looks like you didn't tighten a crew all the way down or you totallt left one out. Also double check the seating of the light. For some reason I could not get mine to line up when I did them. After screwing with it for like an hour or two I just went and got a beer. When I came back it just popped right in like it was a wet whore on Friday night. Go figure...maybe it was the alcohol. LOL
