2. Setup and Installation

The JIAN BOLAND Helmet Light is designed for quick and tool-free installation using the provided adhesive Velcro. Ensure the mounting surface is clean and dry before application for optimal adhesion.

1. Prepare the Light: Remove the Velcro surface from the back of the taillight.
2. Prepare the Helmet/Surface: Remove the white protective layer from the matte backing of the adhesive Velcro.

4. Maintenance

Proper maintenance ensures the longevity and optimal performance of your JIAN BOLAND Helmet Light.

• Charging:
  • The light has a built-in 200mAh rechargeable battery.

  • Connect the other end of the USB cable to a standard USB power source (e.g., computer, wall adapter).
  • The indicator light will be on during charging and turn off when fully charged.

It is suitable for use in rainy conditions but should not be submerged in water. Ensure the rubber charging port cover is securely closed when not charging to maintain water resistance.
