You are correct about the timers built into the MTH signal heads.
I do not intend to daisy chain the signals together for prototypical operation. I think Azatrax offers such a device. However, I would like these to work similarly to my ITAD/Cantilever set up mention earlier. I don't the aspects to "mean" anything, just cycle through the colors.
Here's a thought . . . Z Stuff signals seem to have it all! Prototypical designs, integrated circuitry, super easy installation! You can even link them in a snap! Unfortunately, they're a bit pricey. What say you?
Thank you!
