Just to be sure that you understand:

The pads for the led on the pcb are for a led that will flash following the envelope. If you want a led that remains on all the time (that will not flash) you don't use those pads. You have to wire your led like a normal status led. If you don't know how, go to tonepad.com and looks at the pdf with the wirings diagrams.

You also can use 2 leds if you want (1 indicator and 1 following the envelope) but to do so, solder one of the leds directly on the pcb (without wiring it to the 3pdt switch) and use those unused poles of the 3pdt to wire your indicator led.

I hope this is clear enough.
