I do not have a '16 so I can't tell you from personal experience if the light will be blocked... but, I was concerned with finding the lowest boxes I could as I had reasons for the lower profile boxes. These are just recommendations for lower profile boxes:
I used two pelican cases, to keep the center unobstructed. You could use a pelican assault rifle case if you wanted one longer box but very low profile. Pelican cases are as sealed as you can get and very tough. I also like the aluminum one redrocket posted, seems like a nice box.
Just imagine the obnoxious light bar not being there
