Greetings,

I posted a thread a few weeks ago about how I am wanting to have a grade crossing protected by traffic signals that the crew can switch to either let the railroad or the auto traffic have control of the crossing.  Here is a link to that thread:

Now that I thought I had it figured out, I am into the wiring and started it this morning, but nothing is working for me and I would appreciate any help and guidance you may have!  I have six of the Walthers LED traffic lights, two of which are double-sided (for the auto traffic) and the other four are single-sided (for the rail traffic).  I am trying to use a DPDT switch to control this since I thought that would be easiest and I have one on hand.  For power, I am trying to use a 9-volt battery.  I have added resistors into each of the LEDs, 470-ohm resistors to the single-sided lights and 1,000-ohm resistors to the double-sided lights.  Here is how I have it wired right now:

So I have two options - either red for the rail and green for the traffic or yellow (proceed) for the rail and red for the traffic.  I am not using the yellow phase for traffic and am also not using the green signals for the rail.  I want the DPDT to either be center-off or go to the rail or auto.

Here are some photos showing how the wiring looks and a shot of the signals on the layout surface - once I have it figured out, I'll tuck it away better under the layout.

I am wondering if I need to have the black wires from the LED traffic lights go through the other connector on the DPDT switch (so have one going to the colored wires, the other going to the black wires on each end) and then have the negative from the battery going to the other DPDT connector (so the center connectors would have the positive and negative from the batter).  But I wanted to ask on here before I try that so that I don't damage anything.

Thanks in advance for your help!  And let me know if you need any more information from me.
