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.
