Here’s a product that met with a high level of enthusiasm: it reached 744% of its funding target on Indiegogo crowd funding website back in December 2015, raising $235,622.
Revolights are a totally different approach to bike lights. Instead of the usual front and rear lights which are either clipped or fastened to the bike frame or handle bars, etc, these are rings containing 24 equally spaced LEDs which clip to the wheels; 8 of those LEDs will be on at any one time. As you can see, they illuminate not only part of the front and rear wheels, as well as the road, but are also very visible from the side. This works because the products incorporate an fork-mounted magnet and an integrated accelerometer which provide speed and orientation data to the rings, allowing the LEDs to illuminate only when oriented at the front or rear of the bike – depending on whether they are on the front or rear wheel.
By constantly tracking your wheel speed, the Revolights are able to detect when you hit the brakes and alert people following you with a first-of-its-kind brake light, by flashing at a rapid rate.
The lights create a spread of light, lighting up the ground as well as elevated objects like signs. You may have seen some cars fitted with lights which light up the ground underneath the car, after some research showed some years ago that this made the vehicle more visible to other road users, and I can imagine that this applies to cyclists whose bikes have Revolights fitted.
Now that the crowd-funding campaign is successfully concluded, look for the products – including an Android or iPhone app – to be available around the middle of 2016, in good time for the darker autumn and winter months.
