Hi Steve,
The Dollar is a Eraser Type Track Cleaner that works pretty well. Just erase and wipe with a clean dry rag. The Round Black thing is a Humidity Gauge. Once I turn the heat off for the winter, I keep the Humidity around 55% using a De-Humidifier in my Finished Basement.
The Bridge Lights are working 100% thanks to your Perfect Diagram for dummies.
That really hit a home run for me.
Here are a few pictures of the finished product under the layout.
Thanks again.
