Overview
How Does the PDW Gravity Plus Brake Light Work?
The PDW Gravity Plus USB Tail Light has a built-in accelerometer that detects deceleration or swerving and automatically changes to a super bright, solid beam of 100 lumens to warn following traffic. It runs on a USB rechargeable li-polymer battery, and a USB-C recharging cord is included.
To let the accelerometer calibrate, always install the Gravity Plus on your bike before powering it on. Hold the power button for 1 second to turn it on or off, then keep your bike still for 1 second to complete the calibration. It has two modes, Solid at 20 lumens (12 hours) and Flash at 80 lumens (30 hours), a weatherproof exterior for all season riding, and included seatpost and seatstay brackets that mount the light vertically or horizontally.
