Here’s an interesting idea for improving bike lights and night time visibility. Revolights is a Kickstarter Project that places LEDs in a ring around the wheel, timed so that it provides a constant beam lower down, lighting up the road around you:
From the video, I’m not 100% convinced that they’re quite bright enough yet, but to be honest, I adore the effect. Tron light cycle comparisons aside, I’m just a fan of how they look when moving. I really hope this project gets some attention, funding and development – in a few years this might be the kind of thing that gets built into the wheel itself.
