By obviously I meant the usually found ones are 12V.
6V can be obtained, older volkswagens etc, lorries, coaches have a lot of
24V, but some have moved upto 48V and I've heard of some 72V rails in
commercial vehicles although rare.
The readers we had were very particular about the filament, it had to be
straight and even, any kinks, bright spots or different filament styles
would not work reliably.

What I'm more worried about is a spare bulb -
It's a "festoon" bulb
That style lamp is still readily available over
here (UK) as a car spare
used usually for number plate lights, my Fiat uses them.
What's the voltage ?, the available type are obviously 12V.
Not 'obviosuly'....
Old cars used 6V electrics, lorries, etc use 24V (still, AFAIK). Good car
parts shops can often get 6V and 24V bulbs as a result, which are used in
classic computers. For example, most of my Trend paper tape readers use a
12V 21W bulb, a very standard car bulb sold everywhere. But at leat one
uses a 24V 24W bulb. It took some finding, but a commerical vehicles
parts place had it in stock.
