headlight problems, need help ASAP
 

i have a 90 GT mustang, stock. when i drive at night with my headlights and fog lights on for about 20 minutes, the headlights as well as the fog lights turn off but the parking lights remain on. after turning the switch on and off a few times the lights will turn back on but then go off again in a few minutes. i upgraded my alternator to 130 amps thinking that was it. it wasnt.
any help would be apreciated, i need lights!

Sounds like your light switch.
