This Car Is Posessed!!

Help!! My 1990 Acclaim is posessed!! I was driving along when I noticed my high beam indicator was on. Not so weird except for the fact that my headlights were shut off. When I got home however and turned the car off, the headlights remain on as well as the high beam indicator. The only way I can shut them off is to disconnect the battery. Any help to resolve this one would be greatly appreciated.

Thanks

unplug head light switch first( isolates) it sounds like a positive short
