NJ International drawf signals

I have purchased approximately 10 NJ International drawf signals #1100. I need some help in figuring out how to wire these signals with my tortoise switch machines. What should I use as a power source? Should I use a power bus? What size resistors would you recommend? Any help would be greatly appreciated.

If the lights are LEDs, you can drive them directly off the two power leads to the Tortoise drives, pins 1 and 8. The Tortoise itself is sufficient resistance, although you may want to use different resistors to balance the brightness of the lights. The lights go in series with the Tortoise.

Hi,

There’s some discussion here you may find useful:

IIRC the #1100 is a bulb-based signal?

Good Luck, Ed
