What is better than a bike light to be seen? How about multiple bike lights that react to motion? LucidBRAKE is a stop sign-shaped brake light that mounts practically anywhere and is waterproof and lightweight. It features a three axis accelerometer that is able to detect braking forces relative to gravity and lights up much like a brake light on a car.
It offers two different braking speeds but also can be set to random blinking mode to help ensure it is seen at night or adverse weather conditions. LucidBRAKE is now looking to Kickstarter to get this thing rolling.
