Vehicle is a 87 Weekender

So a week ago as I was blasting towards Lake Powell for a weeekend of
debauchaery, it was past Midnight, cruising around 75 when I dimmed the
lights and- BAM- no headlights! I pulled back on the dimmer lever and the
high beams came on,. If I held the lever back in "flash" position I had
lights otherwise I was in stealth mode, disconcerting.  I cruised that way
until I could find a side road. I pulled off took a deep breath. I switched
the lights off and on and they came back on, no problem. Is there a circuit
breaker somewhere I don't know about? So far no problems, everything works
fine.

P-Mail me for the "wall-o-mud" story from the rain storm that night.
