A local train buddy shared this tip and trick with me that I'm in the process of using on my layout.
In order to install many lights on your layout, use a piece of HO track as bus wires. One rail of the HO track is the hot bus wire, and the other rail is the common bus wire. Doing this is a way to have only 2 wires, hot and common, connected to the transformer (or Atlas Connector) and the HO track rails, and each lamp post or light is connected to the HO track rails using drop wires from the lights.
Will post photos later.
Have a Merry Day after Christmas, Arnold
