Lucnt SRL1: a smart bike light that knows when you are braking

Rayo: a bicycle tail-light designed for the modern cyclist

Lucnt SRL1 is an intelligent bicycle tail light that works like a car’s brake lights. It knows when you are slowing down or speeding up and will emit different flashes of light to warn those behind you.

The gizmo comes from a small Californian company called Mema Engineering. Approximately the size and weight of a USB thumb drive, it attaches easily to your bike via strong magnets. There’s no power switch to fiddle about with as Lucnt knows when you are in motion. The light uses multiple sensors coupled with smart algorithms to sense your speed. The four individual lights automatically brighten when you brake and turn off when the bike is still.

The light can be attached one of two ways. In the flipped-up position Lucnt puts out a steady red light, ranging from 10% brightness during a ride to 100% brightness when you slow down. When flipped downward, the light blinks in different patterns to reflect your changes in speed, changing to a steady red glow whenever you are braking.

To remove the light, simply pull it off its mount. This also ensures against theft. Anytime you lock your bike, simply remove Lucnt and slip it into your pocket.

With just over 20 days to go, the project to make this bike light a reality is about a third of the way to its goal. A model will set you back $100 and it runs for 20 hours on a single charge.
