7. Troubleshooting
While these LED bulbs are designed for wide compatibility, certain issues may arise. Here are common troubleshooting tips:
- Flickering or Error Messages: The bulbs include a built-in driver to prevent common issues like flickering or dashboard error messages. However, a small number of highly sensitive vehicle models may still require an additional CANbus decoder.
- Radio Interference: The integrated design aims to prevent radio interference. If you experience static or signal loss, ensure the bulbs are properly seated and connections are secure.
- Bulb Not Lighting Up:
- Check the electrical connection to ensure it is fully seated.
- Verify that the vehicle's fog light circuit is receiving power.
- Due to the non-polarity design, incorrect orientation is unlikely, but re-seating the bulb can sometimes resolve connection issues.
