John Rumm coughed up some electrons that declared:

Again, its a LED power on indicator, do we care? If so, add another
couple of diodes to the reverse path and a second LED mounted close the
the first; or use a dual chip LED that looks like one indicator but has
two devices internally...


Did anyone say "bridge rectifier"? 4 diodes (or one small package, 4 leads),
1 led and 100Hz flicker, which I'm fairly sure would not be perceivable to
most people.
