what does the wiring diagram look like for a amber light that is switched by 24VDC but actually powered by 120VAC?
thanks

I do not understand your question.
Let's suppose the question is something like this:
I have an amber pilot light that requires 120 VAC or thereabouts to make it illuminate. Separately I have a 24VDC circuit that when 24 V is present I want the pilot light to turn on.
Since 24 VDC won't directly power the light. and if it were directly connected to the 120 VAC pilot lamp it might damage the pilot light assembly, then you need some sort of relay or power generator from 24 VDC to 120 VAC to operate the light.
Why not use a 24 VDC pilot light?
Note: many 120 VAC pilot lights for industrial purposes use a 6 V bulb and a step down transformer built into the pilot light assembly. Change the assembly to one without a transformer and put in a 24 V LED. Vastly simpler than using a relay.
How you draw your circuit first depends the circuit design.

I haven't seen or used the transformer driven lamps in quite a while now. We currently use LED cluster lamps for indication. They are neat and simple and come as a single unit and in various colours including amber. And they're as cheap as chips.Note: many 120 VAC pilot lights for industrial purposes use a 6 V bulb and a step down transformer built into the pilot light assembly.
