Okay, so it sounds like the "parking lights off with headlights on" was only a 
"feature" on early US models. Does that sound right?

While our switches sound exactly alike in every other respect, mine does not 
have the VW part # on it anywhere, although it does have the VW logo. I have 
some late ones, however, that have the part # molded into the plastic.

Me too. I'd like to think that this explains everything if we could just all 
get to your level of understanding. 

It's also odd that you mention looking at the wiring diagram in the early 
Bentley while he says there is nothing there. Are we all thinking about the 
same "early" Bentley? Did Bentley finally come out with a "late" Bentley that 
covered the early cars? I need to look at my early Bentley, which is a thin 
black cover book with very sparce info in it.
