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.
Aren't most "12V" automotive lamps really rated for either 13.6 or
14.4 volts? I know this is a nit, but I seem to remember that the
automotive types are slightly different from normal 12.6V "pilot"
lamps, even when they share the same base.
Festoon bulbs are also found in marine lighting and can be obtained
in halogen configurations in 12 and 24 volt varieties.
What's the response of the sensor? IR or something in the visible
range? I've seen white-LED replacements, but if it's an IR sensor,
that probably isn't going to do much good.
