If you are looking for exact same spec for Concours, then sorry I can't
help you.
But if your are looking for similar performance, I'm sure the Cibie
Halogen main beam units that Chris Witor sells would be perfect
replacements. I've had this units for a number of years, and their
light flow is very satisfactory.
Speaking of lights, the most worthwhile improvement one can do is to
install relays and proper grounding for the main and dipped beams. Using
high quality relay units, this will in fact also improve the reliability
of the system as well as the light output. This is due to the fact that
the standard light switch, as it gets old and worn, will not be able to
withstand the high current. I've had my light switch fail once, and that
is just one time too many, thank you very much.

Main beams should be set up to give as good light as possible, really.
Straight ahead and parallel sounds fine.
For amateur use, I find it easiest and most accurate to set up the lights
on a deserted and straight piece of road during a dark night. Mask the
lights (on the MkII by fixing some cardboard to the chrome grille
surround, for instance) so that only light unit shines at a time.
The dipped beam should be set up so that the horizontal line *just*
disappears. Any main-only beams should be set up to illuminate the road
as far away as possible.
Ideally, you should have someone sitting in the drivers seat when you do
these adjustments.
