Alright guys, the mystery is over, the 2013-2017 Altima master window switch has lights in the door unlock and window lockout buttons in addition to the main window button, which makes the light 200% better over the stock switch that has a light only in the main window button.
if anyone is missing a light there in the dark winter, buy this as an upgrade for 40-50 bucks. see pics below.
thanks again pyro for making that observation in the first place.
the passenger side probably has lights too.. i might just get one to match. i told myself i wasn't going to modify this car but i am ill i guess
