Designer Paul Cocksedge has launched a set of circular bike lights on Kickstarter that snap together magnetically so they can be locked to a bicycle simply by slotting them over a D-lock.
Cocksedge said he wanted to design a stylish light that also confronts issues associated with theft and glare resulting from light sources that are too bright.
"I’ve used many bike lights but I feel some things could really be improved," the designer explained. "The inspiration for Double O comes directly from the shape of the bicycle. I wanted something that almost looked like the bike had designed it itself."
The round lights feature a polycarbonate shell with a robust silicone backing housing 12 LEDs that are more spaced out than the densely arranged ultra-bright bulbs used by many other bike lights.
Cocksedge said this configuration produces a bright glow that is less dazzling for other cyclists and car drivers.
"We use more LEDs at less power, which means the harshness is gone but the brightness hasn't," Cocksedge pointed out. "There is no compromise, you can see and be seen."
A button on the back of the light enables the user to switch between steady, flashing and eco modes.
The lights contain magnets that allow them to clip onto a bike mount when in use and snap together to protect the LED surface when they are removed from the bike.
Once attached to one another, the two lights can be slotted over a typical D-lock and locked up with the bike so cyclists don't need to carry them around.
Cocksedge has launched a campaign on crowdsourcing website Kickstarter aiming to raise £75000 to fund prototyping, tooling and manufacture of the product.
