In the UK, all the cars I owned (from 1951 vintage on) has an ignition light
indicating that the engine could be started (on my early Fords there was
often a red IGN, a green OIL, as well as a blue MAIN beam lens) ... with the
engine stopped, the IGN light indicated that power was being fed through to
the ignition circuit (the points and - contact breakers -coil circuit, and
if left in that condition, you would run the battery down, and also could
have a very warm coil).
The IGN light also served as a warning that the charging circuit was faulty
or indicate that the fan belt had departed: when showing faults (very
briefly): cars with dynamos (generators) it would glow sometime quite
brightly at low RPMs, and with an alternator, just glow all the time. I
should add there is an art to interpreting the various indications of the
IGN light that can make trouble shooting much easier to undertake .....
My guess is the terminology associated with the IGN light can be traced to
Joe Lucas, the Prince of Darkness!
