hey guys im new to this but i could sure use the help my 93 mustang headlight,high beams or fog lights do not work all the other lights do what could be causing this  

first check ur fuses,which ever one is broke replace it,then check ur lights.then consider replacing the switch.if there dash switchs not that much under 100 dollars if it is in the steering column switch 120 to 150 dollars for replacement.it could be ur wires.put the car on a lift get under it get a visual on it.last but not least the bulbs,got to summit or late model restoration,try those websites and good luck
