When we heard that Maxxon’s Wireless Brake Light would use “Nintendo Wii” technology we didn’t know what that meant, but in essence the light is equipped with an accelerometer that detects a sudden deceleration and turns on a bright solid red light, so that those behind the rider will react much as they might to break lights in a car. It offers auto power-on capability as well s auto power-off, and the Wireless Brake Light provides steady and blink modes as well. Not a bad way to help alert drivers when riding at night or dusk.
