- Magnetic Mounting & Wireless Charging: Secure magnetic attachment allows for quick installation and removal. Lights can be charged wirelessly using any standard Qi wireless charger, including MagSafe compatible devices.
- Durable & Long Battery Life: IPX7 waterproof rating ensures reliable performance in all weather conditions. Enjoy up to 35 hours of runtime in battery saver mode, minimizing charging concerns for extended rides.

Operating Instructions
1. Power On/Off
Press and hold the multi-function power button on each Firefly light to turn it on or off. The lights will typically remember their last used setting.

3. Turn Signals and Brake Lights
To activate turn signals or automatic brake lights, a Lumos Remote (sold separately) is required. Pair the remote with your Firefly lights via the Lumos app. The remote allows you to signal turns, and the integrated accelerometer in the lights (when paired with the remote) will detect deceleration and activate brake lights automatically.

Maintenance
1. Charging
Recharge the Firefly lights regularly to ensure optimal performance. Use a standard Qi wireless charger. A full charge provides up to 35 hours of runtime in battery saver mode.
2. Cleaning
Wipe the lights with a soft, damp cloth. Avoid using abrasive cleaners or solvents that could damage the casing or LEDs. The IPX7 waterproof rating means the lights are resistant to water immersion up to 1 meter for 30 minutes, but they should be dried thoroughly after exposure to water.
3. Storage
Store the lights in a cool, dry place when not in use. For long-term storage, ensure the lights are partially charged (around 50%) to preserve battery health.
Troubleshooting
- Lights not turning on: Ensure the lights are fully charged. Press and hold the power button for a few seconds.
- Lights not pairing with app: Make sure Bluetooth is enabled on your smart device and the lights are within range. Restart the app and the lights, then try pairing again.
- Turn signals/brake lights not working: Verify that a Lumos Remote is properly paired and functioning. Check app settings for correct configuration.
- Short battery life: Ensure the lights are fully charged. Check the selected brightness and pattern settings in the app, as higher brightness or complex patterns consume more power.
- Magnetic mount not holding securely: Ensure the mounting surface is clean and free of debris. Check that the universal mount is correctly installed and the light is fully seated on the magnetic base.
