In article , Bruce says...

The pilot light in the switch is between the two travelers (you can
use multiple lighted 3-way and 4-way switches in the same circuit),
and they send the pilot light current through the ceiling light
filament - remove that big lamp, and all the pilot lights in the
switches go out.

Right, but the present question is, how do they implement
the pilot light at the four-way switch? Seems to me they
really would need two neon lamps there to make it work.
