Comment 4 for bug 1192996

A little more about where this occurs:

Well into "Installing base system" somewhere around console-setup the indicator light stops working, and does not work for the rest of the installation. The caps lock functionality continues to work. Upon rebooting into the OS, the indicator light continues to not work, and the caps lock functionality still does.

setleds +caps turns the light on and setleds -caps turns it back off.
