Whilst I have only used UK signals, I have found all types of signal work correctly with the Enhanced Interlocking Towers.
Have you checked in your path definition within the EIT that you have set the signal state to "Proceed" or "Automatic"?
As another question, when you say "Others, like the kuid2.... stay off." do you mean they are not illuminated? In UK terminology, when a signal is "off" it means it is showing a proceed aspect, ie.not red.

What more could anybody want?
