Setup and Installation
The ENFITNIX Xlite 100 comes with a saddle mounting bracket for secure attachment to your bicycle.
Mounting the Tail Light
- Attach the saddle mounting bracket securely under your bicycle seat. Ensure it is firmly tightened to prevent movement during rides.
- Screw the Xlite 100 tail light onto the mounting bracket. The threaded design ensures a stable connection.
- Verify that the light is facing directly backward and is not obstructed by any part of the bicycle or saddle bag.

Initial Charge
Before first use, fully charge the device. Refer to the 'Charging' section for detailed instructions.
Operating Modes
The Xlite 100 offers both Manual and Automatic operating modes, along with smart sensing capabilities.
Dual Operating Modes

Image: Dual Operating Modes. This image displays the switch on the back of the Xlite 100, allowing users to select between 'Manual' and 'Auto' modes.
- Manual Mode: Functions like a standard tail light. Press the button to cycle through light patterns.
- Auto Mode: Utilizes smart sensors to automatically control the light.
Smart Light Sensing

Image: Smart Light Sensing. This image highlights the high-sensitive ALS sensor in the Xlite 100, which enables automatic operation based on ambient light conditions. The light automatically stops during daytime and starts at night. It also features an auto shut-down in approximately 10 seconds when exposed to high light intensity environments.
In Auto Mode, the integrated high-sensitive ALS sensor detects ambient light:
- Automatically turns the light ON at night or in low-light conditions.
- Automatically turns the light OFF during the day or in high-light conditions after approximately 10 seconds of exposure.
Self-Adaptive Technology

Image: Self-Adaptive Technology. This diagram illustrates how the Xlite 100's self-adaptive algorithm compensates for gravity (G) on sloping roads or non-horizontal installations, ensuring accurate braking detection regardless of the mounting angle.
The Xlite 100 incorporates a self-adaptive algorithm to ensure correct braking detection. This technology helps to avoid false positives caused by gravity when cycling on a sloping road or if the light is installed in a non-horizontal position.
Easy Control and Light Behavior

Image: Easy Control Chart. This chart details the light's behavior under different conditions for both Manual and Auto modes, including movement detection, light intensity, and braking. Note: Only the front button can turn off the light when operating under "Manual" mode.
The light's behavior varies based on the selected mode and environmental conditions:
| Condition | Manual Mode* | Auto Mode |
|---|---|---|
| Movement detected + High light intensity + Lasts for 10s | On | Off |
| Movement detected + Low light intensity | On | On |
| No Movement + Lasts for 60s | On | Off |
| Braking | Brake light (Max on) | Brake light (Max on) |
| Any other condition | On | Off |
*Note: Only the front button can turn off the light when operating under "Manual" mode.
Charging
The ENFITNIX Xlite 100 is equipped with a Micro USB port for convenient recharging.

- Locate the Micro USB port on the back of the tail light.
- Connect the provided USB cable to the light and to a standard USB power source (e.g., computer, wall adapter).
- A charging indicator light on the back of the device will illuminate during charging. This light will change color or turn off when charging is complete.
- Once fully charged, disconnect the cable.
Maintenance
Proper maintenance ensures the longevity and optimal performance of your Xlite 100.
- Cleaning: Wipe the light with a soft, damp cloth to remove dirt and debris. Do not use harsh chemicals or abrasive materials.
- Storage: Store the light in a cool, dry place when not in use. Avoid extreme temperatures.
- Charging: Recharge the battery regularly, even if not in frequent use, to maintain battery health. Avoid completely draining the battery for extended periods.
- Water Resistance: While IPX6 waterproof, avoid prolonged submersion. Ensure the USB port cover is securely closed to maintain water resistance.

Troubleshooting
If you encounter issues with your ENFITNIX Xlite 100, refer to the following common solutions:
- Light not turning on:
- Ensure the battery is charged. Connect to a USB power source and check the charging indicator.
- If in Auto Mode, check ambient light conditions. The light will not turn on in bright environments. Move to a darker area to test.
- Press the power button firmly to ensure it's engaged.
- Braking sensing not working correctly:
- Ensure the light is securely mounted and not loose.
- The self-adaptive technology should compensate for angles, but extreme angles or vibrations might affect performance.
- Light turns off unexpectedly in Auto Mode:
- This is normal behavior if the light detects high ambient light for more than 10 seconds.
- If no movement is detected for 60 seconds, the light will also turn off in Auto Mode to save power.
- Charging indicator not working:
- Try a different USB cable or power source.
- Ensure the cable is fully inserted into the Micro USB port.
