I can use some lights in signal routes, I ask because only one W1 model works for me and those from the workshop do not work.

Maybe do not Tag everyone. I can't help you but there are very good Map creators how check the Forum about every hour.

There are many signals from the base content which work. There is even a Light Signal which works.

The "Ampeln versch. Varianten" is not working correctly. This is a known problem, but we don't know if this ever will be fixed. I recommend to use the Signals from the Base-Content.
