parking lights won't turn off. even with keys removed from ignition. on 2001 Ford Ranger

battery was drained by key left on over night. recharged battery now parking lights won't go off. replaced headlight switch. still is a problem. have to remove positive battery cable so battery wont drain. head lights turn on and off fine

i would trace down a short to ground or short to power, simple volt meter can trace down your ansewr
