Default 2007 lariat with no headlights


I drove it the other day came home and when I went to go out again the high beam signal on the dash came on when I started it and there were no headlights. I generally leave the light switch on auto in low beam and use the aftermarket LEDs I installed in place of the fog lights like high beams, so I clicked the high beam stick forward and and back (I also drive an economical Japanese car so I get confused on what stick does what in each sometimes) then I moved the headlight switch through each position and nothing. The only time the high beam indicator went off was when the headlight switch was in the off position. I Googled the symptoms and saw things about the relays so I switched the headlight relay with the blower relay and the blower still worked but the headlights didn't. I also have no fog lights. I've taken the headlights out and each socket looks fried and I have tried to include a picture of one of them so hopefully it will show you. I also have something going on with the computer I think bc after I start it up the mileage display goes out the tachometer speedometer and heat level indicators go to 0 and the check engine light abs light battery light and brake light all come on. From time to time both the 4wd indicators flash on and or the milage display will come to life and beeps while running through the auto lamp setting the check service reset and language settings. Sometimes it signals a tpms alert which disappears quickly and everything goes back to the way it should and sometimes it doesn't. All the while the truck runs fine and 4wd works though the indicator doesn't light up and if I shut the truck off and take the key outthe radio will not stop when I open the door and I have to power the radio off manually.
Any help would be great.

"No headlights" are among the least of your worries.... If you're using non-standard lights, you've likely been overloading the supply circuits causing the heat-damaged connectors.

Start by pulling your kick panels and inspecting your grounds for corrosion or loose connections.
