Connect one black wire from the Green LED to one black wire of the Red LED. This becomes your "common" just like the center terminal of your 153 signal. Then connect the 3 wires as you did with the lamp signal.

My only concern is the website says the LEDs operate up to 19V. From what I can tell you are supplying the turnouts and signal heads with 20V? Can you lower the 20V or is this a fixed output?

While my guess is you'd probably be OK operating at 20V, it takes about 10 cents of components to lower the 20V to just under 19V just to be safe. I can draw that up if need be.
