1:53 scale diecast Freightliner FS-65 school bus model that is ready for back to school! Well, as long as the students are 1:53 scale, too. For starters, the roof was painted white, the wheels black and the windows blacked out. The areas around the flashers was also painted black. As for lighting, steady headlights, tail lights and rooftop strobe were added. A couple of circuit boards control the red and yellow flashers giving them a realistic, wig wag pattern, Everything operates on a 9 volt battery that is tucked away inside the model.
