Hi all, New guy here and need some help, 01 Dodge 2500 Diesel, had it for 2 weeks and headlights went out, searched the forum and changed out the Headlight switch(new) and the switch on column(good used) and replaced and checked all fuses and relays, is the relay labled "security" for the headlights, Is there something I am missing, please help, I know I am new but I had to find this forum to get the help I need Thanks Much.

Well I figured it out finally after a few days of and it turned out to be a bad wire in the combo switch on the column(green), repaired and got lights, thanks for your forum.
