To maintain optimal performance:
- Periodically inspect the headlight assembly for dirt or debris that might obstruct light output or airflow around the bulb.
- Clean the headlight lens with a soft cloth and appropriate cleaner if necessary.
- Avoid using harsh chemicals or abrasive materials on the bulbs or headlight lenses.
8. Troubleshooting
If you encounter issues with your BEAMFLY H4 LED Headlight Bulbs, consider the following:
8.1 Bulb Not Lighting Up
- Check Connections: Ensure all electrical connections are secure and properly plugged in.
- Check Fuse: Verify the vehicle's headlight fuse is not blown.
- Polarity: Some LED bulbs are polarity sensitive. If the bulb does not light up, try reversing the plug connection.
- Test Bulb: If possible, test the bulb in another compatible vehicle or with a 12V power source to confirm it is functional.
8.2 Flickering or Intermittent Operation
- CANbus Error: As noted in Safety Information, some vehicles may experience CANbus errors, leading to flickering or warning lights. An additional CANbus decoder may be required (not included).
- Loose Connection: Recheck all connections for tightness.
- Voltage Fluctuation: Ensure your vehicle's electrical system is providing stable 12V power.
8.3 Headlight Warning Light on Dashboard
- This is often related to CANbus incompatibility. LED bulbs draw less power than halogen bulbs, which can trigger a 'bulb out' warning in some vehicle systems. A CANbus decoder is typically needed to resolve this.
