Driving the quattro at night with no headlights.....

In my case we were climbing up a mountain and reached the freezing level. .
.

When I flipped from high beam back to low-   Darkness.   High beams worked
(100W Eurolight high beams!)   Drove to nearest town on high beams hastely
cranked down and right- I felt awful for what other drivers experienced,
even then.   The high beam pattern is high, even cranked down and right as
much as possible.

Got home by moving the high beam circuit to the low beam bulbs.    Used a 4
inch #12 "extension" jumper made at a NAPA parts counter with help from a
very cooperative parts man.   Female blade connector on one end, male on
the other.  Same size as headlight connector.   Total cost, $2.07.

When I returned home, there was nothing wrong to fix.
Since then, no reoccurance even in freezing weather.   I think what might
have happened was that there was a bit of moisture in the headlight relay
housing left over from a "lets clean out the radiator too" pressure wash.
The relays are behind the front bumper, next to the radiator.  After the
car spent a couple days in 0% humidity, the water was gone?
