I got the ideea to put an dead led to high voltage and it worked.
Step 1: Power source
The power source is from this instructable (http://www.instructables.com/id/Make-an-Ultra-Simple-High-Voltage-Generator/)
-high current supply
Step 2: High voltage supply
Invert the input with the output. Put the led at new output and power supply to new input
Step 3: Result
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.
