What I want to do is modify the casing of the fan so that an
indicator
light shows when the switch is on.
If the switch is off, it is reasonable to assume that if the fan is
running this is due to the humidistat.

It would work equally well if a light came on when the humidistat
was
active.

I just have two posssible reasons for the fan to be running and no
way
of telling which.

If the electrical option is too complex for this reason, there may be
a mechanical solution. The last time we were in the US, the ceiling
fans had a little mechanical doodah on the pull cord to show what
state the fan was in. Although now that I think about it, the fans
(and the doodahs) were designed with 1 off state and 3 on states for
the different speeds. So even if you could find them here (unlikely)
they probably wouldn't be much use for a 2 state device... Sorry!

I already have an external on/off switch with both neon and mechanical
indicators.
The issue is the internal switch (tiny) within the fan body.
I need a very small indicator light to show if power is coming via the
switch or the humidistat - both of which are built into the compact fan
body.
So the indicator has to be integrated into the fan body.
