Follow these steps to install your NULKOMMA E-Bike Headlight:
- Choose Mounting Position: Identify a suitable location on your e-bike's front fork for mounting the headlight.

6. Operating Instructions
The NULKOMMA NKM-HEADLIGHT is designed for straightforward operation:
- Power On/Off: The headlight typically activates and deactivates with your e-bike's main power system or a dedicated light switch, once properly connected to the controller.
- Illumination: The headlight provides a single, powerful 600 LM beam. Its integrated diffuser is designed to illuminate a wide area in front of your bike while cutting off the top end of the beam to prevent dazzling oncoming traffic.
- Horn Function (if applicable): If your model includes a horn, it will operate via your e-bike's horn button, provided the adapter cable is correctly installed.

7. Maintenance
To ensure the longevity and optimal performance of your headlight, follow these maintenance tips:
- Cleaning: Regularly clean the headlight lens with a soft, damp cloth to maintain maximum light output. Avoid abrasive cleaners that could scratch the lens.
- Connection Check: Periodically inspect all cable connections, especially the 3-pin connector, to ensure they are secure and free from corrosion or damage.
- Mounting Security: Check the mounting screws and brackets for tightness. Vibrations from riding can sometimes loosen fasteners.
- Water Exposure: While the headlight is IPX4 waterproof (resistant to splashing water), avoid prolonged submersion in water. If exposed to heavy rain, wipe it dry afterward.
