8. Troubleshooting
If you encounter any issues with your SEALIGHT 9004 S6 Series LED bulbs, refer to the following common troubleshooting steps:

| Flickering or intermittent operation | CANbus incompatibility, voltage fluctuations. | The S6 series is CANbus ready for 99% of vehicles. If flickering persists, an additional CANbus decoder may be required for some sensitive vehicle systems. Consult SEALIGHT support. |
