If you use one of ultrabright leds (2700 mcd or similar), they do
provide enough light as indicators even with 1 mA current. I used those
in one case where I had only 2 mA available for indicator light but even
on 1 mA they are a bit too bright indoors. Of course, they are a bit
more expensive, but then you save with less components and of course
with your electricity bill :-).
