5.2 Battery Care
- Recharge the light regularly, especially after extended use or when the low battery indicator is active.
- Avoid storing the light with a completely depleted battery for long periods.
- For battery replacement services, contact Cygolite customer support.
5.3 Cleaning
To clean the headlight, wipe it with a soft, damp cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these may damage the light's finish or internal components.
6. Troubleshooting
- Light not turning on: Ensure the battery is sufficiently charged. Check if the light activation lockout feature is engaged.
- Light beam is loose or moves: Re-tighten the thumbscrew on the handlebar mount. For added stability, especially on smaller diameter handlebars, consider placing a piece of rubber (e.g., from an old bike tube) under the mount.
- Short battery life: Verify the light is fully charged before each use. Higher lumen modes (e.g., Boost, High) consume battery power more quickly.
- Charging issues: Confirm that the Micro USB cable is properly connected to both the light and the power source. Ensure the power source is active.
- Annoying low battery signal: The light's flashing pattern may become more pronounced or aggressive as the battery level drops. This is an intentional indicator to prompt recharging.
- USB port cover not staying closed: Ensure the cover is properly aligned and pushed firmly into place to maintain the waterproof seal.
