Operating Instructions
Power On/Off
Press and hold the power button on each light for approximately 2 seconds to turn it on or off. A short press will cycle through the available light modes.
Light Modes
Each light offers multiple output modes (e.g., Overdrive, Blast, Enduro, Economy, Day Flash, Flash 1, Flash 2, Pulse). Cycle through these modes by briefly pressing the power button. The Lezyne LED Ally app allows for customization of these modes and their order.
Smart Connect Functionality
Once paired with the LED Ally app, you can:
- Customize Modes: Select and arrange your preferred light modes for both front and rear lights.
- Linked Control: Operate both the headlight and taillight simultaneously from a single control point (either light or the app). For example, turning on the headlight can automatically activate the taillight in a synchronized mode.
- Battery Status: Monitor battery levels for both lights directly from the app.
Maintenance
Cleaning
Wipe the lights with a soft, damp cloth to remove dirt and debris. Avoid using abrasive cleaners or solvents, as these can damage the casing or lens.
Battery Care
To prolong battery life, charge the lights regularly and avoid completely draining the battery. If storing for an extended period, charge the battery to approximately 50% and recharge every few months.
Storage
Store the lights in a cool, dry place away from direct sunlight and extreme temperatures.
Troubleshooting
- Light not turning on: Ensure the battery is charged. Press and hold the power button firmly for 2 seconds. If the issue persists, attempt to charge the light.
- Light not charging: Verify the USB cable is securely connected to both the light and a working USB power source. Try a different USB cable or power adapter. Inspect the charging port for any obstructions or damage.
- App connection issues: Ensure Bluetooth is enabled on your smartphone. Close and reopen the Lezyne LED Ally app. Try unpairing and re-pairing the lights within the app's settings. Ensure the app is updated to the latest version.
- Reduced battery runtime: Battery performance can decrease in cold weather. Ensure the light is fully charged. Over time, rechargeable batteries may experience reduced capacity; this is normal wear.
