Paul Kallus posted:...These are select Railking buildings that include blinking signs wired to the same hook-up terminal as the structure's lights - they do have an off/on switch. I found that the signs need at least 10-11 volts to blink - whereas the building lights come on around 7-8 volts.
Some snippets from an MTH instruction sheet for a blinking-sign building. So the "mystery" as to why it needs 10-11 Volts to blink is explained. So if you want to be able to have the signs blink AND be able to adjust the rest of the building's brightness you will need to install some wiring to separately power the constant lights and what appears to be a "PCB Board".
I tried an image search for the PCB in an MTH blinking sign building without luck. I'd be interested if someone has a knowledge of what it does or can post some close-ups of the board.
