7. Troubleshooting
If you encounter any issues with your QIDEWIN T1 LED Headlights, please consider the following:
- No Light/Flickering: Double-check all connections to ensure they are firm and correctly seated. Verify that the vehicle's power is properly connected and the fuse is intact.
- Incorrect Light Pattern: Ensure the bulb is correctly oriented and fully seated in the lamp socket. Adjust the angle if necessary during the power-on test.
- Error Messages on Dashboard: These headlights feature Canbus functionality, designed to prevent error messages. However, in some sensitive vehicles, an additional Canbus decoder might be required.
- Water Accumulation: Although rated IP67, ensure the headlight assembly's seals are intact for outdoor use to prevent water damage.
If problems persist, please contact QIDEWIN customer support for assistance.
