Aren't these the same lamps that were used on the GTI/GLI grilles?  If so,
replacements are available from the aftermarket:

How about using quad-7'' headlights as in the Scirocco?  Cheap at a
junkyard/Ebay near you.  Has anyone figured out a good way to mount these?
Couldn't you use another round-headlight grille to cut out the trim for the
inner headlights?

I think the real question is what alternative lights are cost-effective
functionally and cosmetically pleasing.  To help my crappy DOT 7''
headlights I use Hella driving lights which, when aimed properly, help out a
great deal.

I will soon be replacing my main headlights with Ciebie H4 E-code
headlights.

Here's a great write-up I found on the SA grille install:
