NettetIf the LED has two leads, one longer than the other,the longer lead is the postive (also known as the anode) lead. If the LED has two leads with leads that are equal in length, you can look at the metal plate inside the LED. The smaller plate indicates the positive (anode) lead; the larger plate belongs to the negative (cathode) lead.
