2.5 LED

Always observe polarity when installing a light diode. The LED has two connection wires

of different lengths. The longer one is the plus pole. It is called

anode

(A). The minus pole,

the

cathode

(K), has the shorter wire.

The polarities are also visible inside the LED. The minus pole has the shape of a large tri-

angle. The plus pole is only very small.
