In a poorly lit area, the PW light helps avoid eyestrain.
In a well lit area, the PW light on one of the lower settings is virtually invisible (i.e. it sure looks like its off even though it isn't).
This is my experience too. However I noticed that the light went out while my PW updated the last time. I assume there must be some reason for leaving it on all the time and it's probably what marcus writes.
