First we need to work on the schematic. The way it is drawn the red and green leds will never light up. Yellow is OK.

You will also want it rigged so if a green is on the corresponding red at the other fixture will be off.

Take a look here and see if you want to use a configuration something like the drawing with three pins (with a little tweaking)

Hello,

In this case would be activated sequentially outs GP4 and GP5 agree to the amendment that I made to the circuit.
