The alternator is simply a little "off" of "spec" and won't excite with the current you are feeding it through the lamp.
Just for GIGGLES, temporarily connect a second lamp in parallel with the first and see if it will excite, or try a 50 Ohm resistor across the lamp.
If that works, you can leave the resistor in place, ASSUMING the alternator doesn't have internal "leakage" that will drain the battery when it sits unused.
Otherwise, you need to replace the alt, or tear into it and check the stator, the rectifier, and the diode trio. If those check out OK swap in another regulator and see what happens.
