Safety Precautions
- Always wear the provided cotton gloves when handling the LED bulbs. Natural oils from your skin can transfer to the bulb surface, potentially reducing its lifespan and performance.
- Ensure the vehicle's engine is off and the ignition is in the 'off' position before beginning installation.
- Allow existing halogen bulbs to cool down completely before removal, as they can be very hot.
- If you are unsure about any installation steps, consult a professional mechanic.
Installation Guide
The FAHREN H11 9005 LED bulbs are designed for a plug-and-play installation, making the upgrade process straightforward. Always wear the provided cotton gloves during installation.
General Installation Steps:
- Identify Bulb Type: Confirm the correct bulb type (H11 or 9005) for your vehicle's low beam and high beam/fog light sockets. The bulbs are clearly marked.
- Disconnect Power: Disconnect the electrical connector from the existing halogen bulb.
- Remove Old Bulb: Carefully twist and pull out the old halogen bulb from its housing.

Troubleshooting
| Problem | Possible Cause / Solution |
|---|---|
| Flickering or Error Message | While FAHREN bulbs are CANbus ready for most vehicles, some sensitive models may still require an additional CANbus decoder to resolve flickering or error messages. Contact FAHREN support if needed. |
| Bulb Not Lighting Up | Ensure the electrical connector is firmly plugged in. Due to the non-polarity design, if the bulb does not light up, simply unplug and re-plug the connector in the opposite orientation. |
| Incorrect Beam Pattern / Glare | Ensure the bulb is correctly seated and locked into the housing. Improper alignment can affect the beam pattern. Re-adjust if necessary. |
