I came across a neon led lit building at Toy R Us for the Cars movie series. It has great neon light effects. Hunting down some more buildings. I purchased the original cars Movie Radiator Springs buildings when they were out many years back and have designed a model train display featuring the buildings and trains for the local train shows that I display at. Have shown them for a few years and it has always been a popular display. The buildings had some nice light effects but limited.
The new Precision series by Mattel have much improved Neon effects that look great with the model train layout. They can be powered with a 4.5 volt wall wart, and have a continuous button to keep the lights on for a show. There are different patterns of light shows with the various lights flashing on and off and different colors.
11 buildings to come out for Radiator springs.
1/43 scale vehicles are a bit large for this but it looks good with the smaller cars vehicles and 1/50 scale models.
