One of the LED lights broke on my GAFC. Does anyone know where I can get a replacement?

Most electronics component supply stores/hobby store will have a regular red led, but does require some soldering skills.

OK thanks. So it's just a basic red LED? I can solder just fine.

GA-FC is a mini computer with a proprietary Double Speed MIDI protocol and if an LED is "out" - might indicate other issues than simply a dead LED
( GA-FC does not like getting wet)

There are no other issues. The led got broken by a mic stand that was in my bag.

Ledvedder, have you successfully replace broken led diode?
I would like to change the last led with green or blue coloured one. But before I start, I would like to know how it went?

Replacing leds is a fairly straight forward job for a 1:1 replacement, but
you need to select the replacement with the led output intensity as a consideration, high brightness ones can be annoying in a foot pedal.
Also the led forward voltage needs to be accounted for, red/orange/yellow and most greens are usually a direct replacement, but blues/whites/purple require a higher voltage/current to run, and may require the current limiting resistor to be changed.
Also with leds, observe the correct polarity.

I'd temporarily use a pot to set the required brightness, then measure the resistance to select an appropriate resistor for the permanent fix.
