Runners all face a similar dilemma when exercising after dark: how to stay visible and safe while pounding the pavement. The designers at the Million Mile Light saw this dilemma as an opportunity – and they’ve developed a lightweight flashing light that is 100% powered by a runner’s movement. Their Kickstarter campaign launches today, bringing runners one step closer (pun intended) an environmentally-friendly safety light that will never run out of juice.

Married duo Tom and Charlie Lawton, of Positively Human, have been hard at work developing their creation. Tom describes the birth of the idea: “I was on an evening run at the end of autumn and it was one of those runs where I felt like Forest Gump. The only thing I was racing against was the setting sun. I live in the sticks and the pavements on the way home aren’t all lit by streetlights. Cars whip by at such a speed they almost blow you over. I wondered if I could use some of the energy I use running to power lights that would keep me safe.”

Several months later, the motion-powered light had been perfected and it’s now ready to be launched. The Million Mile Light is waterproof, all-weather resistant, and shines brightly with its powerful LED lamps, providing 200+ meters of visibility and a 120 degree fan of light. Boasting an impressive endurance of 100,000 hours (and a 5 year manufacturer guarantee), this battery-free powerhouse is great for even the most intensive training.

Each Million Mile Light uses neodymium rare earth magnets – which are actually not rare at all, but common as copper or nickel. The team warns against pregnant runners using the device and to make sure electronic devices are strapped to a different part of the body than the light (wrist wraps are also available for the unit). The product was designed to light up during vigorous, as well as slower paced running.

The Kickstarter campaign offers the first lights to early-bird pledgers for £12 ($19). Later supporters can receive a light by pledging £15, or $23.50 USD, which is a discount from the standard price of £19.99 ($30). With so many active runners looking for a safety solution for nighttime excursions, there is little doubt that the team will reach its £35,000 goal.
