The Blaze Laserlight is not strictly a wearable, though I suppose you could strap it onto your bike helmet instead of your handlebars if you wanted. And it’s not really a Health Tech device, except in the preventative sense; it is designed to help cyclists avoid collisions and the injuries that would likely result from such impacts.
The Laserlight looks a lot like bicycle headlight, with a bright light that you can set high, low, or flashing. It also contains a green laser that projects the image of a bicycle onto the road surface about 20 feet ahead of you. The concept is that this extends your visible footprint, and drivers will see the green image on the road ahead of them when you’re riding in their blind spot beside them. The driver should then be more aware of your presence, and will be more likely to avoid maneuvering into your path.
The headlight uses a power-efficient LED, giving an estimated 13 hours of use between charges when using both the headlight and laser in flashing mode. You get up to two hours when both are in full brightness, constantly-on mode, which should be plenty for most evening commutes. The company asserts that the laser is “retina safe,” and costs 125 British pounds (about $200).
