There are many products on the market to recreate these effects, and even more versions of the signals themselves in every scale. You can follow the installation using the products and methods seen in this new article, or you can mix and match. Most products will work in a similar manner, just check with the manufacturers' instructions for any peculiar installation steps.
It only takes a few hours to protect your tiny motorists, and you can install a signal like this at just about any stage of construction on your railroad.
