Bi-directional or Bi Color LEDs have 2 colors in the same bulb that can be lit independently of each other by energizing the wire that wire corresponding to the color.

BiColor also called BiPolar LEDs, have a single ground and 2 hot (positive) leads.

These LEDs are 3mm.

Use these bi-directional LEDs anywhere you need an indicator light.

Connect the black wire. Connect one red wire for green. Disconnect and connect the other red wire for red. Great for control boxes, and other indicator uses!

All of our LEDs come with a 2 year warranty!

I purchased 50 of these bi-leds. They all worked flawlessly. Shipping was timely and in great condition.


These are advertised as AC/DC/DCC. They are not true AC like the other universal LEDs. But still work Great!

Hi Travis
Thank you so much for taking the time to leave us a review!
We appreciate it!
I want to let you know that the BiDirectional works very well on AC power as we used them this way.
Can you let me know what issue you encounter when connecting them to AC power?
It is only necessary to connect the center lead to a separate power than the 2 red leads, then it will work as expected! We are here to offer further support if needed!

This Led is just what was needed for the Lionel No. 6-2163 Auto Block Target Signal
The Bulbs lionel provided would make the signal housing melt but not this works perfectly
Sorry LEDS were NOT around 50 years ago

Great Led

First time I have seen bi-color leds. These leds are great! I am using them on my model railroad as turnout indicators and couldn't be more pleased. They come pre-wired so there is less soldering to do plus, you save time and money because you eliminate another set of 1 color lights. I recommend these lights for any small hobby project. Evan Designs sent my order out promptly and will order more bi-color in the near future and will order from Evans Design for all my led needs from now on.
