What is this electrical jack for?

I was in the process of changing my right front marker light. After removing the wheel and the inner wheel liner, I saw this jack hanging. I can't find the female end where it plugs into. Does anyone know what the jack is?
Thanks in advance!

Could be for a light that your model doesn't have.

 

Got it. It actually was the connector for the light, the bulb wasn't burnt. The reason I didn't see it right away is because the light had a connector plugged into it. I followed the wire and saw that it goes into another connector/coupler that the wire that is hanging plugs into. What made it even harder to see is that it plugged into the bottom of the coupler, so I couldn't see the opening to jack the plug into.

 

Good question. But got a better one. Is this suppose to be connected to another connector or is this normal? It's behind the passenger fuse panel and tcu is located in same area.
