That's very helpful - thanks! I will take a look at these....
Non working as in you don't want them to light at all?
Oregon Rail Supply makes several styles of plastic signal heads. They also offer a 2 or four track signal bridge that comes with non-working heads but I have wired them using small axial LEDs with great results.

their website is a bit outdated but Walthers and several other retailers handle their products.
This is their two track bridge with position light signals that I added my own LEDs to. They also sell kits with the LEDs supplied. You can make trackside signals with their parts and brass tubing.

Many of the other non-working signals available are just too toy like for my tastes.
Have fun! Ed
Does anyone know of any decent non-working signal models in HO? I think Tomar and BLMA make some nice working models, and then there are those old black plastic things that aren't very realistic. Can someone please help? TIA.
