Uber has patented a light to go on top of cars that can signal to customers when their ride is arriving.
The patent was first filed in May 2014, but it was granted to Uber only on Tuesday. It describes a light bar that sits on top of Uber cars, with a colour-changing section that can be controlled by the passenger's app. The patent also describes how the entire bar could light up and passengers could select different patterns.
