No high beams

I added a hitch and 7 pin trailer plug recently, and just noticed that i no longer have high beams. The low beams work fine, but when kicking on the brights the headlights just shut off. After doing a search it seems the dimmer switch goes out all the time, but would it just be a coincidence that it went out at the exact time I did some other wiring?

Or could I have done something else to cause it to have no brights?

Can't see how it could be related. Sounds like dimmer switch. They were probably out before and you just hadn't noticed.

Sounds like dimmer switch and yes coincidences can happen. I just recently had an old tape player in one of my old cars jam up and kept on trying to eject killing the battery over night i thought. Ended up the battery had just lived it's life time and went dead. It was just a coincidence they both happened at the same time. It was good it happened in my drive way than out in the middle of no where .
