There is a set on ebay right now (no affiliation w/ seller).
I have seen nice sets in the $100/
pr range on ocassion. Concours ones will be significantly more. New ones are like $350 each I believe, if still available.
What you want is Hella 169's. These are mine (not for sale, sorry), w/ the original clear lenses, then with the amber lenses (from Stoddard):
