The Blaze light is an elegant answer to the perennial blind spot issue.

The most dangerous place for cyclists is just behind a vehicle going in the same direction.

When a car or truck makes a right turn, a cyclist is not far enough back to be seen in the rear-view mirror, and not far enough in front to be spotted from the windshield. The cyclist is invisible, unless drivers take a conscious look over their shoulders.

It's this problem that the Blaze light tries to solve. By projecting a green image of a bike a few feet in front of its wheel, the light effectively elongates a bike's presence on the road, telling people it's arriving before it gets there.

"Having a bigger footprint on the road helps you be seen in time," says Emily Brooke, a young British designer who first developed the concept at college in 2011.

Blaze is actually two lights in one. It includes a conventional white light and a green laser projection unit.

After graduating, Brooke ran a successful Kickstarter campaign, then raised more than $800,000 from investors to build the Blaze brand.

You can now buy the light online for $200.

This Bike Light Projects An Image Of A Bike, So Cars Know What's Coming

The Blaze Light projects a green image of a bike a few feet in front of its wheel, effectively elongating the bike's footprint on the road and warning drivers of its presence.

For cyclists, the most dangerous place on the road is just behind a vehicle going in the same direction.

Aside from drivers turning in front of cyclists, Brooke points to two other dangerous scenarios the Blaze corrects. One is when cars pull out of side streets onto larger roads. Research shows that drivers tend to look in the middle of the lane, but not along the curb where cyclists are, she says. The other involves pedestrians who listen for cars, but don't bother looking for cyclists. A green light in front of their toes means they're less likely to step out and cause an accident.

Brooke says drivers also tend to give Blaze-users more space on the road. "One thing we've heard from early users is that motorists are taking longer to cut back in after overtaking," she says. "They'll wait until they've gone past the green symbol before going back to the lane."

$200 is a lot of money for a bike light, no question. But it could be a small price to pay for a safety innovation.

  • What a great idea.

    I'd like to know if they tested different images, and different angles though. Obviously they're using the standard bike image, but what if it was rotated so that the image looked like a bike moving forward? Or maybe include an arrow to indicate the direction of the bike? (Will this ASCII example help explain what I mean: = o/\o => )
