The mechanical modification of the indicator dials is a story in itself, with dark lettering on a light background changing to the reverse and back again. More recently, changes have come in the form of employing different light sources and display technologies.
The vacuum fluorescent display has evolved from single cylindrical tubes in 1970 to the thin-film devices used in the automotive industry today. Vacuum fluorescent displays are similar to cathode-ray tubes in that they generate light through electron bombardment of a layer of phosphor...
