At least in some systems, ¡°dark¡± is a valid appearance, at least for parts of a mast.
So JMRI uses the lit vs unlit language to try to separate ¡°the signals lamps are not powered due to e.g. approach lighting¡±; ¡°dark¡± is used to mean ¡°this signals appearance includes this lamp not showing any light¡±

It should be mentioned that when a signal is dark, it would still have an
aspect, like stop or clear, it just would not be lighting the output. This
is needed because other signals next to it would base their aspects on the
aspect of this signal. If the concept of signal logic is integrated inside
the signal, it being dark should hide what state it would show should it
become lit.
