Setup the lights on the breadboard like a traffic light. Red on top, then yellow, and then green. The small red and green are the pedestrian crossing signals. Again red on top and green just below.

In my images I am using the right side positive run of the breadboard as negative because its easier to put in the LED.

Put the cathode (-) into the negative run of the breadboard and the anode (+) into a hole next to it.
