If you have a DMM with a diode check feature, just probe the LED terminals.
When you have the positive lead on the anode the DMM will indicate a forward
biased diode junction and the LED will light up!
LEDs have higher forward voltages (much higher for blue ones) than
ordinary diodes, so some meters may light the diode, but show full scale
and some may not even light the diode.
My meter will light up to at least green, but shows an off scale drop
for even red.

RFC1855 says there should be an address here, but, in a world of spam,
that is no longer good advice, as archive address hiding may not work.
