The stall warning light mounted in the center of the left hand panel
in the PA28-235 doesn't require the crew's attention; it gets it. So
I guess it's approved.

There's a good chance that in the case of the PA28-235 that the light
is not required at all due to natural stall warning and Piper just
put the light there just for good measure.
