It develops solutions for signal lighting bicycle wheels, which can be clearly seen from all sides. Two aluminum hoop with LEDs mounted on both sides of the wheel near the rim and rotating with the wheel. Thanks to the accelerometer, when driving LEDs are constantly on and off, so that light is strictly the front of the front wheels and the rear of the rear wheel of the bicycle. The front wheel is lit with white light, rear – red. Light from the LEDs is in the sides and back, working position lamp, as well as forward, lighting the way to velobaykerom no worse than ordinary lights.
