Product news: this magnetic bicycle light by Danish design studio KiBiSi lights up instantly when its two halves snap together.

The iFlash One was designed by KiBiSi to meet a new Danish law requiring cyclists to attach their lights securely rather than dangling them off the frame, which had been common.

When not in use, the front and rear lights connect magnetically into one compact object that can be kept in a pocket or bag.

Cyclists can choose between a flashing or steady light, which lasts up to 60 hours.

We've published lots of bicycle accessories on Dezeen, including a pair of jeans with a belt loop that can stow a bike lock and an inflatable helmet that folds down into a scarf.

Other KiBiSi projects we've featured lately include a desk that can be wound up and down and a sofa that looks like a rolled up mattress.

Here's some more information from the designers:

iFlash One is a bike light created for intuitive use and easy storage, accommodating modern day lifestyle on the go. iFlash One uses magnets for easy fastening, effortlessly clicking onto a magnetic base which is permanently fixed to your bikes handlebars or seat post. Once connected the light turns on automatically. When not in use the magnets pair the front and rear unit into one compact object ready for storage in your pocket or bag.

Colour codes on the front and rear lights indicate placement and opposing magnet directions ensure correct positioning on your bike. iFlash One gives you the possibility of either a flashing or steady light, providing 60 hours of battery life in flashing mode. The integrated wide-angle lens ensures a safe ride while fulfilling the new Danish legal requirements for bicycle lights. Whether you want a perfect match or a little contrast on your two-wheeler, iFlash One has a range of colour options to choose from.

"iFlash One is designed with a holistic approach, merging light and fitting into one object with an overall and simple DNA. I like that the magnet seems magic. Making safety fun and easy through simple everyday usability has been key in this project," says head of design at KiBiSi, Lars Larsen.
