The simplest constant current limiter with 'load indication' - A very simple constant current limiter circuit with a tricky load indicator

So if we used the circuit as a constant current charger then the LED performs as a 'charging is ON' indicator. The circuit has tricky bias so the LED is working there as a reference voltage (Vref) regulator and also as a load indicator. And I made it possible just using four cheap components.
