Hi Stuart, a slight feeling of deja vu about this topic between you and I. I use, with no regard to the pattern on the glass looking authentic, 61/2" Stanley reflector units - which take a BA20D bulb- ex 1960s I think Honda motorcycles. They take an integral sidelight bulb also. With Chinese double dipping LEDs and a LED B9a sidelight bulb they give me very acceptable night vision. The headlight bulbs require 12V so I use a DC-DC up convertor from 6v battery voltage. Sadly these units are like hen's teeth but I see no reason why other M/C 61/2" units wouldn't perform equally well.
I feel I must say that, in my experience, the front "lens" which is cleverly designed and multi facetted, on modern reflector units is key to the performance, not least the production of a "flat topped" beam.
