BOB:
While I am dubious about being able to make these work with MV lenses,
don't overlook http://www.miniatronics.com/Merchant2/merchant.mvc. They have
some nice headlights in incandescent and LED. See my article in the "S Gaugian"
about the gas-electric. All electronics there, except the drive-train itself,
came from Miniatronics. I think it was the Jan/Feb 2007 edition. Now evaluating
their multi-unit structure/building lighting bar with the tiny/mini-LED's for a
product review for Don H. Also, as an aside, Miniatronics has the best 1.5v
bulbs I've ever seen. No glob of insulation at the base of the bulbs.

Yes Ed, I have done a test in the last couple of nights using the
surface mount LED mounted in a MV lens. My impression with the resistor
provided, was that it was just a bit dim. The problem with the surface
mount unit is that it's like a bare bulb where the light is emitted in
all directions. The more typical larger bullet shaped unit focuses
light, which better imitates the polished reflector in a steam era
headlight. I smallest unit that I've seen of this type is 3mm--what
would be ideal is one that is about 1 to 1.5mm and had flexible leads.
I see that Richmond does mentions a 2mm size--I will investigate that next.
