A-Trac Button Color

Has anyone changed the illumination of the A-Trac Button?

I removed the switch but there doesn't appear to be a light bulb or place to install an LED.

I'm looking to change the illumination to white.

 

There should be small printed circuit board inside the button housing that contains the physical switch, the LED, and likely some resistors.

If you disassemble the switch housing (there should be some detents holding the portions of the housing together) you should be able to desolder the existing LED from the board and resolder a new one in its place.
