Researchers at the Massachusetts Institute of Technology are looking at how to use lights from solitary cyclists to ensure higher visibility on the road.
The university is working on a way to make illuminations from the bikes come together to pulsate at the same cadence and in turn gain more attention.
MIT's development could be especially important on city streets after-dark in order to make lights make bikes more visible to other cyclists or drivers.
According to researchers at the school, the bikers may not know each other, or may only be passing each other briefly, but for the moments they are together, their lights synchronize.

The effect is a visually united and draws inspiration from nature.
The idea comes from fireflies illuminating in unison or crickets chirping together; situations which otherwise may go unnoticed.
'Fireflies provide a spectacular study of the synchronous flashing of light across large swarms of insects in the night,' a statement on the overview of the project said.
In the same way: 'When bikes are alone, their lights stay steadily on. When bikes are near each other, their lights pulsate from high to low, back to high, in synchrony.
'The bike lights are programmed to behave as simple oscillators, and the amplitude of their light is a function of their phase. As their phase oscillates, the amplitude of light does as well.'
Research found that bikes broadcast their phase over radio and receive messages from nearby bikes.

They follow a custom synchronisation algorithm to match each other's phases.
'Bikes exchange messages peer-to-peer in order to align their phases of oscillation and synchronize the pulse of their lights. These messages are broadcast by the bikes over radios that are tuned with a limited transmission range, so that bikes only synchronize when near, and swarms can dynamically form, change shape, and dissolve as bikes move throughout the city.'
When unsynchronized nodes come into proximity they act as a swarm of two but when they move way they fall out of sync.

Now MIT has designed a peer-to-peer radio protocol and algorithm to allow a decentralized network of bikes to effortlessly synchronize.
New bikes can join or leave the network at any time.
MIT said the synchronization algorithm is open source and there is no globally synchronized clock so bikes need not share their identity, nor need to know any information about others.
While the school tested it out on bikes, MIT says it could work on scooters, skateboards, and any other swarms of sustainable transit.
'We built this light system. We designed a synchronization protocol and algorithm, as well as physical prototypes that we fabricated and tested on our local city streets,' the school said online.
