Decathlon Motion Light Flashing Run Light, No Battery Required

Out team of runners has designed this autonomous run light to ensure you can be seen by drivers at night or in low light.

A LAMP WITH NO BATTERIES? HOW DOES THAT WORK?

Do you understand the dynamo principle on a bike?
The Motion Light works in the same way but through an oscillating movement: at each stride, the magnet moves into the coil and generates the electricity which lights the 4 red LEDs.
The result? A simple and practical running light. No need for batteries or even an On/Off button: just wear it and it will light up at each stride!

LIFE SPAN AND AUTONOMY, THIS IS A LIGHT THAT YOU WILL HAVE FOR A WHILE:

Thanks to its dynamo system, the Motion Light does not need any batteries. An eco...nomic advantage:
We have tested this light in our laboratories to ensure that it will still work after 10 million oscillations, i.e. 10 million strides.

10 million strides. Sound good? If you consider that you travel 1 metre per stride, that means a lifetime of over 10,000 km. If you run 1,000 km per year, that means 10 years.
Ready?

WHAT LIES BEHIND THE DESIGN OF THE MOTION LIGHT?

The Motion Light clip has been designed to be attached to thin running clothes: on a loop, pocket, belt, etc. And to give you even more choice, the light comes with an adjustable elastic armband.
We have chosen red LEDs because it is a colour we associated with break lights and slowing down. The light can be seen from 100 m, which gives a car driving in urban areas enough time to stop.
It weighs only 50 g and comes in a transparent case!
