- A South African man has built backup traffic lights for use during power failures

An innovative South African man has built backup traffic lights that could be used during power failures.
According to Nkolisa Bulelwa, the man's sister, the traffic lights do no use electricity. Instead, they are powered by batteries that last up to 48 hours.
Bulelwa shared photos of the traffic lights on her Twitter page, Briefly.co.za gathered. She has not yet provided the name of her brother.
In a subsequent tweet, Bulelwa explained that the lights could simply be placed at an intersection in case of a power failure.
Motorists would then adhere to its signals until the normal traffic lights are powered back on. This would cause minimal traffic disruptions.
Bulelwa added that in case more than one traffic light is required, then there is a master controller that sends signals to the "slaves" within a 200m radius.
She explained that the lights can work continuously for up to 48 hours.
Bulelwa said her brother pitched the idea to the Johannesburg Rail Agency. However, they allegedly told him that the industry is highly regulated.
She also confirmed that her brother has patented the designs.
Social media users applauded Bulelwa's brother for coming up with the innovation.
