It is sometimes possible to get the beacon moving for a while with a
quick nudge, but it rarely spins for long.* Another manufacturer
(Lionel) had a similar product which they withdrew and replaced with a
motor powered beacon because the heat version was unreliable.

Assuming the 'heat version' relied upon waste heat from the lamp, a
resistor could provide much more heat than a bulb.

And fry the LED at the same time.
