Honestly, I've got a bunch of mongrel LEDs that I've picked up here and there. Quite a few of them have leads nearly if not identical in length. Life's too short to go fiddling with them. Stick 'em in one way. If they work, great, if they don't, turn 'em around. The one this weekend actually had leads of differing length and I had it right the first time, then tore the circuit down and rebuilt it (power supply for amplifer) slightly differently with the LED in backwards. Cussed and put it in the other way. Worked.
Cussin' is a great way to communicate to a device that it's not doing what you wanted it to do.
Note that I didn't say that the device actually responds to said cuss words, but neither do they respond to polite parlor talk so you might as well cut loose and have fun.

Lightbulb Transparancy is the word!

Most of the times you can see trough the LED and see a difference in the inside between both leads. I belive it was the anode that had a small element inside the led and the cathode a large element. Anyway, once you know this for one LED, it will be the same for the others

For me this works best.

There is an expression here: "to cuss a blue streak" With that in mind, I suspect that if I cuss enough a red LED might turn blue. Given that red ones are cheaper than blue, perhaps I might be onto a money saving measure.
