5. Safety Information
- Always disconnect the vehicle's battery before performing any electrical work.
- Ensure all wiring connections are secure and properly insulated to prevent short circuits.
- Mount lights securely to prevent vibration and detachment during vehicle operation.
- Do not look directly into the LED lights when they are on, as this may cause eye damage.
- Verify that the installation complies with all local and national regulations for vehicle lighting.
- The yellow wire must be connected to an ACC (Accessory) power source or the positive electrode of the power supply for proper function of all light modes.
6. Setup and Installation
Follow these steps for proper installation of your Kewig K11S Auxiliary LED Fog Light Kit:
6.1 Mounting the Lights
- Identify a suitable mounting location on your vehicle, such as handlebars or crash bars. Ensure the location provides a clear beam path and does not obstruct other vehicle components.
- Select the appropriate sleeve size (22mm, 25.4mm, or 28.6mm) for your handlebar diameter.
- Attach the mounting bracket to the light and then secure it to the chosen location using the provided hardware. The bracket allows for 360° angle adjustment. Tighten all fasteners securely.

6.2 Wiring Connections
- Connect the red wire from the wiring harness to the positive terminal of your vehicle's battery.
- Connect the black wire from the wiring harness to the negative terminal of your vehicle's battery or a suitable ground point on the chassis.
- Connect the yellow wire to an ACC (Accessory) power source. This connection is crucial for enabling all light modes. If an ACC source is unavailable, connect it to the positive electrode of the power supply, but be aware that the lights may remain on when the vehicle is off if not switched manually.
- Plug the auxiliary lights into the quick disconnect connectors on the wiring harness. Ensure a firm connection.
- Mount the control switch in an easily accessible location on your handlebars.
- Secure all wiring with zip ties or electrical tape to prevent chafing, entanglement, or damage from heat and moving parts.

9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Lights do not turn on. | No power, loose connection, blown fuse. | Check battery connections. Verify all wiring is secure. Inspect the fuse in the wiring harness and replace if blown. Ensure the yellow wire is connected to a power source. |
| Only one light works. | Faulty light, loose connection to one light. | Check the quick disconnect connector for the non-working light. Inspect the light for visible damage. |
| Lights flicker or dim. | Insufficient power, loose connection, voltage fluctuations. | Ensure stable 12V power supply. Check all wiring for secure connections. |
| Cannot switch between all light modes. | Incorrect yellow wire connection. | Ensure the yellow wire is correctly connected to an ACC power source or the positive electrode of the power supply. |
