John,
You can connect a 12v led indicator in parallel with the fuse, it

will
light up if the fuse blows, regarding fixing them in flight, I

would
want to know why it had blown before replacing it, not easy to
diagnose electrical faults and fly safely at the same time!

Fuse blows it there is a short in wiring. You would like to

continue
supplying current via LED to shorted wires, so you can see that

fuse was
blown?

Yes, 3-5ma through an LED and it’s dropper resistor is not going
to cause any problems, it’s not like I suggested using a car
headlamp bulb!!
I would be interested to know why you think that it would be a
problem.
