Puddle/approach light or the outside temperature sensor.

Funny...I was just looking at that today. One of my puddle lights is out on the tow mirrors and I looked at them before I ordered replacement LED lights.. When I saw it, I was wondering if it reads the outside temperature.

It's the outside temperature sensor, they are only on the 2013+ trucks.
