I need some help for wiring I meen I have a lot of street lights and traffic lights and the power pack can only take 2 cords, does it go into another control box or something?
I wire my lights in a parallel circuit. In this way, two wires can carry power to however many lights I want. At one time, I had 90 lights on my layout, all fed by 2 wires.
I built a small control panel just for the lights. I sub-divided the lighting into groups, light street lights, signal (incandescent), signal (LED), yard towers, buildings, etc. That way I can turn on and off individual groups.
