As of right now, the current Intel drivers/firmware in the iwl
architecture for Linux do not make use of the LED (past drivers in the
ipw3945 architecture did make use of it), so it doesn't come on at
all, even when active. This is controlled entirely by software, it
would seem, and may be a method of attack to set up a bridged network
without anyone noticing. Of course, that would mean getting something
onto the system anyway, possibly at a root level.

I prefer the physical switches that Dell uses, instead of the buttons
used by HP.
