3mm Bi-Colour (bipolar)RED/White LED, with Common Anode (+).

Common Anode bi-color LED schematic Normal Bi-Colour LED's just aren't DCC friendly. The standard is to have a common Negative (Cathode) terminal which just doesn't work too well with the common + supply (Blue wire) provided on most DCC decoders. OK, so you could use two individual LED's or even a relay or transistor circuit, but this adds bulk, and extra components.

Introducing our first Common positive (or bipolar) LED.
Simple to wire, just connect the common anode(+) lead to the blue decoder wire (Via the included resistor), and the remaining wires to the White and Yellow decoder wires (depending on your requirement for Red or White lighting) Animated LED

This LED is a clear red/white colour, with the colours carefully balanced to be suitable for prototypical modern locomotives and rolling stock.

We Include a 680 ohm resistor, so you're ready to go!

N.B. - The LED does not really flash! it's controlled by the DCC decoder.
