where i can get this indicator

hi,
I’m looking for some indicator that looks like this:

it’s called SAS rotary type indicator.
This indicator is electromagnetic, so when power is applied to the indicator, its show white segment
when power is not applied to the indicator its hide the white segment.
i’m not sure about how much is the volt for this, but i think its between 1-3 volt

do you know where i can get this , or something similar to this indicator?
thanks
