Hi All. I was just helping my mom get some decorations out of her garage. One box opened and some plastic easter eggs fell out. One clear one opened and and landed on its flat open ends. I stared at it for a moment and visualized headlight lenses for tank lights like a spaceliner or other tank bikes that have dual lights. They can be cut, sanded or trimmed to fit a lot of things. While not being a museum quality piece, they may help complete that rat rod tank hanging in the rafters because lenses are so expensive. I guess another thing to look at for the same purpose would be the plastic shells of toys in gumball machines. There is my idea for the day. Cheers
