Reply to "switch direction lights"

I was suggesting that the COMMON (center terminal) wire from your block signal should go to the AIU SW "IN" terminal for the turnout...which, in your case, is also the "U" terminal of the transformer. So whichever is more convenient.

As soon as you make this connection, I believe one of the two block lights will turn on. Then when you fire the turnout via the AIU, that light will extinguish for exactly 1/2 second and the other light will turn on as the turnout changes position. Again, one lamp (red or green) should always be on. What you were describing was the backward case where both lights were always off and one would momentarily turn on when the turnout is fired.
