Hi to all !

I have this 3 pole filter in my receiver's last stage. I want to put a led, so when the current is passing through my circuit the led will light on. I need this because my transmitter a lot of time, don't work fine, so i don't know if there any signal going to my receiver.
It is a way to check it.

Any ideas for cheap consuption ?'
