That's true. Also the green light does not signify that the surge
protector is properly grounded. I have a Ruby (tm) EMI/RFI surge
protector. As an experiment, I plugged it in (with an adapter) using
only two prongs (not the ground). I wasn't surprised that the red
light went on, but I was surprised that the green light still went
on.
