I assume, but don't know for certain, that MacBook keyboards are USB HID devices. In that case, this document:
http://www.usb.org/developers/devclass_docs/Hut1_11.pdf discusses extended HID usages, including those which can be used in toggling on/off controls, of which LEDs are one instance. From there, I'd go to the IOKit framework and see what APIs exist for playing with OOCs. IOHIDUsageTables.h contains useful constants.
