Here are the facts.

1. I have instrument panel lights.
2. I have dome light.
3. I have turn signals, front and back.
4. I have parking lights, front and back.
5. I have brake lights.
6. I have license plate lights (rear)
7. When I pull the headlight switch know out to the headlight position...rear light remain lit, but after 15 seconds or so the headlights will begin flashing.

Regarding #7...here's what I have checked.

1. When I disconnect either one of the headlights, the other REMAINS lit continuously.
2. I have tried #1 on both headlights, respectively.
3. Using a multimeter, I have tested voltage on the headlight switch, dimmer switch connections, all connectors on the headlight wiring going
from the headlight switch to the actual headlights. I have done this combined with both headlights connected and individually on each headlight with
the other headlight disconnected. I have 11.5 volts consistently on power WITH NO fluctuations. Of course, this is with the headlight(s) lit.
4. I have CLEANED all terminal connections on the headlights with a electrical terminal spray on cleaner, from the switch to the headlight(s).
5. I have re-attached all body grounds using star washers.

So, what is left? What have I missed?
