My 6 y/o grandson, who has Asperger's, is fixated on traffic lights. I thought I might help him create a Halloween traffic light out of three pumpkins. My idea was to get some sort of a tube, cut holes in the pumpkins, and slide them over the tubes like a totem pole. Then I would attach light bulbs to the tube in three places and put a red light in the top, a yellow light in the middle one and a green light in the bottom.
What type of light would be best? I was thinking of low voltage lights to make wiring simpler and reduce shock danger. I know I can get 110 v bulbs and fixtures anywhere, but what about low voltage?
I also wanted to make them flash independently. Again, there are little insert disks that fit into 110 v sockets, but is there anythng for low voltage?
I checked one small local lighting store, but they didn't have much. I'd appreciate suggestions for stores or online places.
Thanks
