I am trying to replace the bulb in a headlamp of Lionel steam locomotive 6-18064. The bulb is extremely small maybe 3 to 5/16th of an inch with two wires. The bulb is no longer made a Lionel dealer told me. I tried a led but that did not work. I am not sure what the voltage and wattage should be. Any idea? And, where I could buy a small incandescent bulb with two wires? I would enterain led but have had no success perhaps I am uisng incorrect volt or watts.
