In the pursuit of being able to control as many things as possible digitally, while keeping effort to a minimum, I went down the rabbit hole of controlling some of the scenic accessories via DCC. Currently I have two buildings with functions that I want to turn off and on at will: a lighthouse, and a windmill.
Some time ago I took delivery of my first batch of signals. These are generic 3-light signals made in China. They aren't particularly prototypical - the aspects resemble a type of signal used here in Queensland, as well as some European signals. But the looks are very basic. However, for first experiments and wrapping my head around the subject matter, they are more than sufficient.
