Traffic lights come in all shapes and sizes, but for the most part they've remained the same for a long time. Just because they're consistent, though, doesn't mean that there aren't tweaks that can be made. These modular traffic spheres do away with the average vertical arrangement of red, yellow and green.
The CEF traffic light is different in that it doesn't exactly get rid of the formula, but simplifies it for the driver. When it's bright outside, it can often be difficult to discern what light is on display, but with the CEF light only the current light being displayed is visible. It does this by rotating the horizontal spheres that contain each different light.
