Answers.Text: @user253751 It won’t need to be an _exact_ match, but too far off won’t work well. Something between 2.9V and 3.1V should be fine, and you can get most colors in that size in that voltage range. For example, an Inolux INL-3AW30 should work perfectly well here (though that is admittedly the _only_ 3mm through-hole white LED around the right voltage range I found with a cursory search through my usual go-to for this type of thing).

  I'm not aware of 3rd party sellers that offer these in alternate colors, but it doesn't look terribly difficult to do yourself. There is at least one [video covering the process](https://www.youtube.com/watch?v=Rhcr5wX0-SE). Here's the gist:
  
  1. Take the base off with a screwdriver
  
  [![Disassembly step 1](https://i.sstatic.net/qB85w.png)](https://i.sstatic.net/qB85w.png)
  
  2. Remove the original LED
