re:  the "driving lights"

I think these should be thought of as high beams just like in a
4-headlight system.  That's how I'm going to wire mine when I finally
get around to it, i.e. no extra switch (but extra relay for sure).

I'm one of the "Joel Cohen" customers (before Ken had them I think),
and the extra lights Joel provided are mounted in sheet metal brackets
that will perfectly pop-rivet to the sheet metal of the grille
opening.  They look a lot like the aux lights on the first-generation
Rabbit convertibles, which I've only ever seen from a distance.  I
suspect they are the genuine SA setup.
