Designing a three way light box, Designing a three way light box

[Englewood]

I want to design a 3 way light box.

The box will switch on from 24v input, so I need the box to run at 24v.

Basically I want the box to show:

Standby
Immanent
ON

"Standby" in green. (Always on)
"Immanent" in orange (only on when switching)
"On" in red

So when the box is powered on standby is always on.

"Immanent" is a warning to say the system is about to be turned on, I want "Immanent" to flash for 5-10 secs then when it switches from "Immanent" to "ON" I want the "ON" to stay on.

The light box will get a signal from another source telling the box to switch to immanent then switch to on.
Any ideas guys or any more information required?

I'm thinking if the standby is operated by 24v in constant,

If the immanent is switched on by another 24v in and also the ON.

I could possibly use transistors to switch the lights on at certain points.

N way toggle (Exclusive OR) requires 3 wires in a loop.
3 way Inclusive OR requires 3 wires in a star configuration between all stations but means any ON switch can defeat the off.

What do you need? Inclusive or Exclusive OR?

imminent seems useless if the LEDs provide feedback.

I was thinking of something like this.

With 2 relays but I cant get the LED for Immanent and ON to work.
