First thing we need to know is what the voltage is at the secondary
of the transformer (which WILL be AC) and if there is anything between
the transformer and the switches (like a rectifier). It is UNLIKELY
there is a rectifier because there is no advantage to using DC on the
bulbs. The #14 bulb is rated at 15 hours at 2.5 volts, and if the
voltage is only 1.5 volts the lights will be dimmer (but the light is
only for "realism" so it does not need to be full brightness)

Dim light is okay if they are dancing or watching tv, but if they are
doing homework or reading, a brighter light is much better.

and the
lifespan will be in the hundreds of hours.. This was commonly done in
doll houses and scenery for train sets etc.
