not a bad idea. I wonder if it could be done with an rgb led

Does this light work on Iphones, I noticed you have a samsung and when I assembled mine, the LED never lights(polarity is correct and wiring is correct) And when tested the jack should drive enought power to light the LED (I tested a 1W 8Ohm speaker which worked on the jack.) But the LED never lights even when I know the jack is working. I also tried multiple LEDS.

I have an iPhone SE.

Nice thinking! If you use a headphone splitter you can still use your headphones while getting LED notifications.

This would be great to bring to the library!

It doesn't work. Can't even strip the plug !

mantap gan...

Maybe a stupid question. Do you plug out when you answer the call? I think speaker and microphone will be off when it is plugged in.

No. you can loudspeaker your call

I suspect this will only work if you have some kind of notification sound enabled with enough energy to light the LED. For instance the Pop on my droid probably won't work.
