I played with my lights a little - not sure if this will help:
PS. When I say "Light Switch ON" I mean two detents - i.e. Headlights, not just parking lights. I also get two lights on in the instrumentation - one on the tach, and one on the speedo.
1. Ignition OFF / Light Switch ON: Parking lights are on - Headlights are down and ON, even thought the buckets are retracted.
2. Ignition ON / Light Switch ON: Headlights come up and the lights are ON as the bulbs are coming up.
3. Ignition ON / Light Switch OFF: Headlights OFF as soon as the switch goes to OFF, and then the lights retract.
4. Light switch OFF, then Ignition OFF (during retraction): Headlights freeze when the ignition switch is shut off.
