  • Forward current: 20mA (typical)


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.


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:-
