Tonight I started the truck, pulled the headlight switch on all the way out. I thought all lights were working fine. Pulled out of the front gate, parked it, got out to close the gate behind me and noticed the front of my truck looked dimmer than usual. Walked to the front and noticed my drivers side park light was out. I popped the hood and wiggled the park light pigtail a little. It came back on, then immediately turned off. I looked over at the passenger side patklight and noticed it too was off. Looked down the side of the truck ALL of my running lights were off all the way around the truck. Headlights were still on and working fine. Got inside the truck, no gauge lights. Dome light works fine. Brake lights work fine. Back up lights work fine. Hazard lights work fine. What gives?
