Although we've seen bike headlights, tail lights, turn indicators and brake lights before, the Blinkers system from Zurich-based Velohub wraps them all up in a particularly slick package. It also throws in laser lane markers, and wireless remote control.
Blinkers consists of a 200-lumen headlight unit, a 100-lumen tail light/laser unit, and a handlebar-mounted RF controller. With the press of a left- or right-hand switch on that module, a strip of LEDs above each of the lights illuminates sequentially to indicate the direction in which the cyclist is turning.
The dual laser lane markers are activated by pressing a button in the center of the remote, while an accelerometer and gyroscope cause the brake light to come on automatically when the bike decelerates.
The two waterproof lighting units attach to their bike mounts magnetically, so they can simply be pulled off when not needed (or when the bike is left unattended). Battery life varies with brightness modes selected, although the designers claim that one USB charge should be good for about seven hours of use. The remote's coin cell battery should be good for about six months' use.
Additionally, ambient light sensors can be enabled to automatically adjust the lights' intensity according to how dark it is outside.
Blinkers is currently the subject of a Kickstarter campaign, where a pledge of €89 (about US$99) will get you a complete system – assuming it reaches production.
