Bill,
They did work the other day. The wires are orignal and I checked all connections. When I looked up the headlamp switch it didn't look like the one that's in there. It's old and looks like it could be a replacement.
The brake lights work without the park lamps on, but when I turn the park lights on and step on the brake pedal they don't work. The rear park lamps are not working at all. The signal lights work and the front lamps all work fine.
