7. Maintenance
- Cleaning: Use a soft, dry cloth to wipe the LED bulbs and remote control. Do not use abrasive cleaners or solvents.
- Remote Battery Replacement: If the remote control's range or responsiveness decreases, replace the CR2025 button cell battery. Ensure correct polarity when inserting the new battery.
- Storage: When not in use for extended periods, store the bulbs and remote in a cool, dry place.
8. Troubleshooting
- Bulbs not lighting up:
- Check if the bulbs are correctly inserted into the socket.
- Ensure the vehicle's power is on and the lights are activated.
- Verify the remote control battery is working and the remote is pointing towards the signal receiver.
- Remote control not working:
- Replace the CR2025 battery in the remote control.
- Ensure there are no obstructions between the remote and the LED bulb's signal receiver.
- Confirm the remote is within effective operating range.
- Inconsistent color display:
- Some users have noted that the 'white' and 'yellow' colors may not perfectly match true white or yellow. This can be a characteristic of RGB LEDs.
9. User Tips
- No Memory Function: Please note that these bulbs do not have a memory function. The color and mode will reset each time the power is cycled (e.g., when you turn your car off and on), requiring you to set your preferred color/mode again.
- Remote Aiming: For best results, ensure the remote control is pointed directly at the signal receiver on the LED bulbs.
