4. Setup and Installation
The NULKOMMA Ebike Headlight is designed for easy installation on the front fork of your e-bike. Follow these steps for proper setup:
- Choose Mounting Location: Identify a suitable location on your e-bike's front fork for mounting the headlight.
- Attach Brackets: Use the provided big or small brackets, screws, and nuts to securely attach the headlight to the front fork. Ensure rubber ring gaskets are used to prevent slippage and protect surfaces.
- Connect Wiring: Locate your e-bike's controller cable. The headlight comes with a 3-pin connector cable. Link this directly to your e-bike's controller cable for continuous lighting.
- Adapter Cable (If Applicable): If your e-bike system requires it, use the adapter cable included in the package to ensure both the speaker (horn) and light functions operate properly. If the horn and light functions are reversed or not turning on, use this adapter.
- Adjust Angle: Once mounted, adjust the headlight's angle to provide optimal illumination of the road ahead without causing glare to others.

5. Operation
The NULKOMMA Ebike Headlight provides powerful illumination for night riding and includes an integrated horn function.
- Headlight Activation: Once connected to your e-bike's controller, the headlight will typically activate with your e-bike's main power or a dedicated light switch, depending on your e-bike's system.
- Brightness: The headlight provides 600 lumens of super bright LED light, designed to illuminate a wide range and focus on objects ahead.
- Beam Pattern: The glass diffuser helps distribute light evenly and features a cut-off on the top end to prevent dazzling oncoming traffic.
- Horn Function: The headlight includes a built-in horn. If your e-bike's wiring supports it, the blue wire from the headlight is typically for the horn. A momentary horn button switch may be required for activation if not integrated into your e-bike's controls.
