Somewhat OT. I have a regular switch for my outside light that lights
when the outside light is on. The curious thing is that my
electrician put it in using existing wiring and there is no neutral in
the box. The house is 70 years old and there are only 2 wires in the
box and the box is not grounded.. How is that possible?

If there are only two wires in that box one wire is hot and one wire
is common. You have no ground in that box. That's the way houses
were wired 70 years ago.

or one wire is hot and one is a switch leg, which IMHO is more common.

Either way, his question was how does the light switch light when the
outside light is on?

No, the OP's question was:

"Are there three-way switches that have indicators (e.g. a light)
that tells you whether the circuit is on or not?"

Not the OP's question. Michael's question, which was all that Gordon
quoted.

Clare mentions a neon light, but they light when the outside light is
off.

It still "tells you whether the circuit is on or not". The neon is lit when
"not".

But that's not relevant to Michael's question.

I can't answer Michael's question. Maybe someone can.

Maybe if you read the question as asked...
