Default headlights stay on...

04-08 screw. I've googled and youtubed like crazy for my answer but haven't.found it. my headlights stay on even when they are turned off and key is taken out, also disconnected the headlight switch. They still stay on. So it's not a bad switch, any input??

Like my coworker said, I too had the same problem. It caused by my own ignorance but still I tried everything before giving in to a shop. But my headlights would stay on after the blew out on low beam. I had high beams, no low beams. I took out fuse #40 so I can travel at night. I checked sensors, switchs, and connections, nothing. It was a costly part I don't know anything about. It solved it and life is normal for me.
