The clever Fabric FLR30 Light packs a lot of safety innovation into a small package. The 30-lumen taillight makes clever use of an incorporated accelerometer to increase brightness as speed falls. The result is a dual-purpose light that alerts traffic when you intend to slow down or stop in order to get drivers´ attention and making sure they see you. The R30 is compact, reliable, USB-rechargeable, and burns for between eight and 12 hours depending on the setting. It is also designed to be mounted in multiple positions.
