7. Maintenance
These LED bulbs are designed for long-term, maintenance-free operation. To ensure optimal performance:
- Keep the light housing clean from dirt and debris.
- Avoid touching the LED beads directly with bare hands during installation or handling.
8. Troubleshooting
If you encounter any issues after installation, refer to the following troubleshooting guide:
- No light: Check the electrical connection, ensure the bulb is inserted in the correct direction (though these are non-polarity, a loose connection can cause issues), and verify the vehicle's fuse for the DRL system.
- Dim light: Remove the bulb, clean the socket and bulb contacts, and reinstall the bulb firmly.
- Flickering or error code on dashboard: Some vehicles, especially BMW models, may require a CANbus decoder to prevent flickering or error messages due to the vehicle's bulb-check system. If these issues occur, please consider installing a compatible CANbus decoder (not included).
9. User Tips
- Compatibility Check: Always verify the specific bulb type (e.g., H8, H9, H11, H16, 9005, 9006) and your BMW 3-Series model (E90, E91, E92, E93) to ensure proper fitment. This is crucial for specific lighting systems like "angel eyes" where different bulb types might be used.
- Error Code/Flickering: If you experience flickering or error codes on your dashboard after installation, a CANbus decoder may be required. This is a common occurrence with LED upgrades in some vehicle models due to their sensitive electrical systems.
