Bring Dead Led to Light

I got the ideea to put an dead led to high voltage and it worked.

The power source is from this instructable (https://www.instructables.com/id/Make-an-Ultra-Simple-High-Voltage-Generator/)

parts:
-transformer
-high current supply
-led
-crocodile clips

Invert the input with the output. Put the led at new output and power supply to new input

My output was at a low current as 20mA  but if the current is bigger the led can break fiscally the epoxy can break. You can put a diode bridge to convert from AC to DC.
