2008 f350 no running lights all fuses and bulbs are good
check the circut breakers under the hood with the fuses. do they move freely? take one out and shake it it should rattle.
check for cut wire(s), the connectors, the ground wire(s), and if there's a seperate switch or if its intregrated into the headlight switch
check for frayed wires, you could have a simple short somewhere.
just had this problem fuse box was toast after changing it had to get the ecu and keys re programed, tip, fuse all the trailer wires before the plug
