Two LEDs placed in parallel facing opposite directions.
§ One LED is red or orange, the
other is green.
§ Current flow in one direction
turns one LED ON while the other remains OFF due
to reverse bias.
§ Current flow in the other
direction turns the first LED OFF and the second LED ON.
Rapid switching of current flow direction will
alternatively turn the two LEDs ON
giving yellow light.
Used as a polarity indicator.
Maximum voltage rating: 3V
§ Operating range: 10 to 20mA
