• Wow, those buttons look awesome! I might have to put an order in for some of those :)

    But as you say, it doesn't look possible to easily change the LED :(

    One more option is a 'voltage multiplier' : https://www.allaboutcircuits.com/textboo­k/semiconductors/chpt-3/voltage-multipli­ers/

    It's still extra components (far more than just a FET) but it would allow you to run the MDBT42 off even a single LiPo battery and still get a higher voltage to light the LED.
