No batteries!

Have to admit I missed the "no batteries" part when I ordered this. Several small magnets move in a coil as it rocks slightly side to side as you run, which induced a current for the LEDs. Very light, completely unnoticeable clipped to my cap or shorts.

Action operated.

Love it: no batteries to worry about. Only had it for short time but very satisfied so far

Good for night runs

Still would recommend running along bright path as one should not depend on this device alone.

Neat little blinker

Love the fact you don’t have to remember to charge it or have the right size batteries. It works at slow jog as well as run. Blinking in time with your step. Doesn’t work when walking on arm (not tested on leg). The strap is small but elasticated so has some give and largely stays in place. Light is noticeable at a distance but not so much that it distracts you with glare up close. Nifty little gizmo.

Nice!

Excellent device, works flawless and produces enough light while running. However, I would like to suggest an improvement. Light is mostly emitted in one direction, when wearing on upper arms either sideways, backwards, or forward. By placing lights on opposite sides of the device, visibility from different directions improves considerably.

Concept good. Shame the clip broke

Very good concept. The clip broke the first time removing it from my jacket. Now it's useless as not sure how to attach otherwise

If life gets in the way...

If life gets in the way and means you have to run in the dark.... this is something I can't leave home without... very light weight and lights fabulously

Motion Running Lights

This is the second pair of these running lights, others are still in use!, just thought it would be good to have another pair, used now for dark evenings twice a week, simply perfect.

Flashing light for running

This doesn’t flash when I run. It’s really disappointing so I can’t use it.

Very useful running light

I currently have to start my training an hour before sunrise and use a Decathlon head torch and flashing red rear light. My wife bought me two of these motion lights for Christmas and they are excellent. They strap securely to each arm and are particularly useful when approaching a crossroads or road junction because they catch the eye and make you visible to others sideways on. It is important to ensure the strap slides beyond the barb under the clip then they will not come off the strap. I have used them for two weeks and they work very well and are quite comfortable. A very useful and clever light that needs no batteries.

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 that 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:

Because of its dynamo system, the Motion Light does not need any batteries. A plus for the environment... and for your pocket: 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 40" per stride, that means a lifetime of over 10,000 km (6,200 miles). If you run 1,000 km (620 miles) 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 color we associated with break lights and slowing down. The light can be seen from 330 feet, which gives a car driving in urban areas enough time to stop. It weighs only 1.8 oz and comes in a transparent case!

Our design team spills the beans on the development of the motion light

The origins of this product can be found in a simple desire: "we wanted to innovate to remove electronic limitations when running." It then took a team of 3 people, 18 months of development, endless discussions with runners, and a commitment: "we were brave enough to say: we are going to make a battery-free product." And after a great number of prototypes, we are proud to offer this simple and practical light. "Our idea was that you would run and we would handle all the rest."

A final tip before setting out?

Gilles, product manager, and Lucie, designer, have some tips for running at night: "It is important to be visible. Especially when running at night in places where you share the road with vehicles a lot bigger than you! In the end, you need to be visible more than to see. Just as you put your shoes on before running, don't forget your light." And for even greater safety? "Ideally, don't run alone" :)

Imported

Product testing

In lab tests, this lamp worked for over 10 million oscillations.

Storage instructions

After use, store the light to prevent any unintentional movements. For example, do not leave it in the trunk of your car, to stop the light from coming on needlessly.
