Here's the brand new edition of the Gravity Tail Light, the Gravity Plus. The Gravity+ Tail Light is both a tail light and a brake light.  It has a built-in accelerometer that detects deceleration or swerving and automatically changes to a super bright, solid beam to warn following traffic. To allow the accelerometer to calibrate, always install the Gravity+ on your bike before powering it on. Hold the power button down for 1 second to turn the light on or off. Then, keep your bike still for 1 second after pressing the power button to complete the calibration.

The Gravity+ Tail Light has redesigned mount that works with the included seat post and seat stay brackets. If you'd like a backpack clip compatible mount, please let us know.
