The shape of traffic lights has barely changed since they were invented. For as long as anyone can remember, there has always been three round lights, one red, one yellow and one green.
Initially, the sections were round simply because this allowed the spherical bulb inside light the glass evenly.
However, traffic lights in present use super bright light diodes that can be arranged in any way. The sections are plastic, which means any shape can be created.
The design team at the Art Lebedev studio has come up with the idea to produce square traffic lights. This can make the signals more easily noticeable and recognizable, with larger lit area for the same overall dimensions.
They are willing to work with road safety councils and local authorities on improving and designing road marking and signage, traffic and city lights, urban furniture, etc.
