4 Tap DC isolator - possible to add an indicator LED?

[Fishbonetabby]

first time long time!

I have an enclosure that already has a hole through the top that was being used for an expression controller I no longer have a need for. Can I just simply wire an indicator led at the input of the 4 tap isolator board so I can re purpose that pre drilled hole? My other option is to repurpose the enclosure upside down to hide an unnecessary hole. I feel like this is probably dumb question but since everyone here is so kind there really are no dumb questions. Thanks in advance!

Yep, you can add an LED indicator. Just make sure you add a current limiting resistor in series with the LED.
