My truck is a 1993 F350 with a jasper 460 engine. Hello! I'm new here, and need help trying to determine why my parking lights stay on even after I turn the lights out. I have to disconnect the battery. It's only the parking lights, and I can't turn them off while the truck is running either. I already replaced the plug directly behind the light switch.

 

Sounds like the headlight switch to me...

 

I already changed the switch. It still does it. But thank you for the reply

 

You changed the switch, the plug going to the back of the switch, or both?

 

Hi yes, I replaced the big square receptacle "male and female ends" that are just behind the switch behind the dash.
