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.
