I recently bought my first car, a 1984 300ZX N/A. There is what I believe to be a short in the head light switch. I can turn my head lights off, but shortly after the park lights turn right back on. I can twist the headlight switch back and they'll turn off, then right back on. I have resorted to un-hooking the negative terminal on my battery so I don's have to charge it every night. Any help is appreciated so I hopefully won't have to buy a new switch.

 

here is a pretty good video on that switch
