The light bulb with blue cap is VW p/n 357 919 062 and is used on
Quantums, Passats, Jettas, Golfs, Eurovans, Corrados, Cabrios up into
mid '90s.  It would be a dealer item.  It was done this way because
blue LEDs did not exist at the time.  Now, unfortunately** they do,
so you could substitute an LED but  you would have to change the load
resistor in series with it from 270 ohms to probably between 470 ohms
and 1000 ohms for current limiting and to produce the desired light level.

**I say unfortunately only because, since they were so late in
appearing compared to red, orange, yellow, and green LEDs which all
appeared within a few years, when they did show up they were exotic
and instantly fashionable in all sorts of unsuitable uses like panel
illumination where they cause problems with visual acuity, power
indicators where nobody would ever have used a blue incandescent
light even though they were readily available since probably the
'20s, mood lighting where they are simply ghastly etc.
