6. Troubleshooting
If you encounter issues with your Nilight JK-222A LED Tail Lights, consider the following common solutions:
- Lights Not Functioning: Check the electrical connection to ensure it is securely plugged in. Verify that the vehicle's fuses related to tail lights are intact.
- Flickering or Dim Lights: This could indicate a loose connection or an issue with the resistor. Re-check connections and ensure the resistor is properly installed.
- Hyper Flashing (Rapid Turn Signals): While the product is designed to be plug-and-play, some vehicle's electrical systems may require additional load resistors to prevent hyper-flashing with LED turn signals. Ensure the provided resistors are correctly installed.
- Moisture Inside Lens: Although sealed, extreme temperature changes can sometimes cause temporary condensation. If persistent moisture is observed, inspect the housing for cracks or damage.
If problems persist after attempting these steps, please contact Nilight customer support.
