Electroluminescence.
Specifically, electroluminescent rope. Various diameters (3mm, 5 mm
etc), powered by an inverter which can run from a 9Vdc battery for
several hours following a ships power system failure. Will not diminish
your night vision (and is NVG compatible!). Not really very expensive.
You could also install a 24x2 inch electroluminescent under the
glareshield. Again, can be powered by a 9 Vdc backup battery.

Rope which, when a current is applied, glows?

So one option is a strip under the glareshield. What about something
lighting each instrument individually? For example, this rope along the
inside of the bezel of each instrument.

I'm asking about per-instrument lighting because this airplane does have
something under the glareshield, and it's not all that effective at
lighting the instruments.

How does the rope fail? That is, does the entire thing go dark at once, do
individual regions fail? Individual strands?

In the notes I was given, I see that one vendor (Fiberlite-Aircraft) uses a
single bulb and fiberoptics to light individual instruments. Though I've
not yet spoken to them, one question will be "what if the lone bulb fails?"

Do you happen to know vendors of this electroluminescent rope? How can it
be installed "properly" in an aircraft? We're running right up against (in
fact, well past {8^) my ignorance level again, but doesn't this require
certain bureaucratic magic?

Thanks...
