Yet, maybe it’s worth asking: Has that design gone unchanged because these traffic signals are a timeless design? Or have we just not thought of anything better yet?

Now, more than 100 years later, the Moscow-based design firm Art. Lebedev Studio believes that they’ve created a better alternative to the classic stop light—with a flexible design that could be expanded to metal stop signs and yield signs, too.

Their new stop light has already garnered attention from two cities in Russia, which have requested to test it in a limited capacity.

Instead of stacking red, yellow, and green lights on top of one another—with each light’s relative position signaling when it’s time to stop or go for color-blind drivers—the studio developed a stop light that’s one continuous panel. And so that entire panel turns red, yellow, and green.
