I just copied the schematic , when the Hakko FX 888 is on , a red led blinks only one  time every few seconds , when you leave the room and want to check if it's still on , you may look when the led is in the off period.

This mod adds a green led to have a permanant indicator.

The bottom left of the circuit is the I.C. of the unit itself.

It works kinda like a logic inverter

PS : Sorry if my english is bad , it is not my first language.

Modify the first two resistors to 200 ohms if voltage around 9 volts, for brighter led's
