Setup
Charging the Lights
Before first use, fully charge both the front and rear lights. Connect the appropriate USB cable to the charging port on each light and plug the other end into a USB power source (e.g., computer, wall adapter). The front light's battery indicator will show charging status. The rear light typically has an indicator that changes color when fully charged.
Mounting the Front Light
- Step One: Place the handlebar mount on your bicycle's handlebar.
- Step Two: Secure the mount by tightening the screw or strap mechanism. Ensure it is firm and does not rotate easily.
- Step Three: Slide the front light onto the mount until it clicks securely into place.
- Step Four: Adjust the light angle as needed. The mount allows for 360-degree swivel adjustment for optimal beam direction.
