"I already had! Amazingly, it was not difficult to determine this by a simple test - but at the outset I expected it to be a common cathode configuration with the cathode being the longest lead, so it was only a 50/50 choice !"

"Alan,
Amazingly the manufacturer does not specify this. You should find the short lead is the green LED."
