How do you identify the terminals of an LED?

To make it easier to identify the leads, all LEDs are manufactured with two physical properties. The first is that LEDs have one lead that is longer that the other. This longer lead is the anode (+), and the shorter one is the cathode (-). The second feature is a small flat notch on the side of the LED.
