1990 Pontiac Sunbird Park lights

Hello, I'd have to check ground and voltage circuits to the lites that stay on. The feed to the park lamps should come from the headlite switch, if the headlite switch is turned off, there shouldn't be any voltage on that circuit. My info shows the feed to the headlite switch is hot all the time, got nothing to do with the ignition switch. Check for voltage on the wires going to the bulb sockets, let us know the color of wires with voltage.
