This Wireless bike turning light is safety at it's best. In addition to the blinking turning lights it also has 3 LEDs in the center with 5 different cool flashing modes plus a large reflective glass on the bottom. The light is meant for a carrier fit and mounts with two screws (included). The control goes easily on your handlebar with a rubber O ring. There are small LED lights under the buttons of the control so that you can see on your control which lights are activated on the taillight. Batteries are included (2 AAA for the light and 1 cell battery for the control).Bright Ideas
