Do you think that the current traffic lights that we have aren’t good enough? Korean designer Hojoon Lim has a way to improve it, with his 4-way traffic lights concept. Instead of you having to look at the lights, the traffic light can project laser beams to “bar” the street, letting you know when you can or can’t cross the street. Aside from the laser beams (which everybody loves), it’s also solar-powered, thanks to the solar panels at the top, ensuring that we have a greener future.
