Just bought cutter 10mm LED, where is positive ?

[cwloo]

Dear,

Just bought some 10mm square XPE led from cutter but do not know where is the positive side to solder. Is that "A" side or "C" side ?

Appreciate the help....

Isn't there a little + sign on the border of the emitter, just follow the trace path from there.

I had to use a magnifying glass to see it on the emitter I have.

Anode - red - positive
Kathode - black - negative

And wheren't electrons going the other way?
