Scale illumination lamps blown. Anyone ever tried droppered blue or white
LEDs for such purposes. Would probably require a reflector on the LED
lighting axis to throw light off radially.

An idea from IRLEDs which are available with wide angle radiation pattern -
and have virtually flat lens instead of domed, you could flatten the end of
some white LEDs (taking care not to cut too deep and take out the bond
wire!) using a medium rough emery paper will leave a diffuser lens end.
