There's no real standard in hardware to play with leds. For example, you
can play witch num/caps/scrol lock leds on your keyboard easily, but
there's no such standard for cheap generic drive enclosures. Fancier ones
use saf-te, as others already mentioned.

What you need to do is to figure out what your case and enclosures use to
implement LEDs and if that is exposed to OS. Only then you can start asking
how to control that from OS ...
