The light ring sits directly under the chrome/trim round piece. Occasionally the ring will seem to fit tighter on one F150 than it does the rest. In this case the solution is to use a small dremel to give yourself more room for the ring to sit and the cup holder ring to secure fully.
It doesn't seem to fit perfect or the chrome ring does not secure all the way. (2009-14)
