Setup and Installation
Charging the Lights
Before first use, fully charge both the front and rear lights. The charging port is located underneath the flap marked "USB" on the side of each light. Pull back the rubber flap to expose the micro-USB port. Insert the provided USB cable into the port and connect the other end to a USB power source (e.g., computer, wall adapter). The charging indicator light, located beside the steel bezel, will turn green when the light is fully charged. A full charge typically takes approximately 3 hours.
Attaching the Lights
The Vont Pyro Bike Lights feature a flexible silicone strap for easy, tool-free installation. Each light also has a built-in clip for alternative mounting options.
- Strap Installation: Attach one end of a silicone strap to the hook on the back of the light. Wrap the strap around your bicycle's handlebar (for the front light) or seat post (for the rear light). Secure the free end of the strap to the remaining hook on the light. Ensure the light is firmly attached and facing the desired direction.
- Clip Installation: For additional versatility, the lights can be clipped onto backpacks, clothing, or other gear. Simply use the integrated clip on the back of each light to secure it to a suitable edge or loop.
