These LEDs are 2 wire dual colour. Basically there are 2 LEDs in the same package wired back to back with the colour changing depending on the polarity of the supply.
PLEASE NOTE:
All LEDs are tested prior to dispatch.
If a supply voltage greater than 2 volts is to be used then a suitable series resistor MUST be used.
A suitable series resistor is available HERE please refer to the table below:-
