I had bought my dog this ball from General dollar. This ball when bounced on the floor lights come on inside it they are red and blue. After a while like all dogs she chewed it up. So I took the light out to see what I could use it for. It was a little too big for “Z” scale which is that I have. So here is a picture of this light that was inside. I think if you put two red lights on it, it would make a good crossing signal. or a police car in “HO” or “O” scale. It has a spring switch now.
