It's a '16.
I did fiddle w/the connector both at the truck to trailer, and at the plug at the light itself (which you can only get to by drilling the rivets out) and could not get more than 2 led's to light. and even those were sketchy. once i put in the new one, they all lit up like they're supposed to. I too was surprised that they went out that early. could have just been a defect from mfr. all it takes is a little crack in the circuit board and some water.
All in all it was not hard to swap it out, but i do wish they'd use something other than rivets.
