Challenges I ran into

My light wasn't turning off - realized that there was no way for FETs to discharge, so I added pulldown resistor manually to USB connector ground. Additionally, I realized that I bias the FETs with too little current, so I added a (janky) parallel resistor to increase the gate voltage.
