Quoted from thundergod76:Doc, when you decided to add the cake pan did you move the led from under the plastic to under the phone inside the cake pan? If so how did you route the wire? Thanks!
Its been a few months but I think the LED under my original chew toy phone was an RGB one so it had solder pads ofr R, G, and B signals with just the red one used. It was too big to fit entirely under the cake pan. I think you could use a spike single red LED board (cointaker has them for a $1 or so) and trim it to just fit inside the black base. I didn't have a spike LED board so I just used a basic red LED (like pic below) with a current limiting resistor. Just make sure you add a current limiting resistor. https://www.digikey.com/en/resources/conversion-calculators/conversion-calculator-led-series-resistor
