Installation Notes and Tips

Verify the vehicle uses a 9004/HB1 bulb type before installation. Confirm whether the application uses high beam and low beam in a single headlamp assembly or a specific headlamp configuration listed in the fitment data. Handle the glass bulb carefully and avoid touching the glass surface with bare fingers. For best results, replace bulbs in matched pairs when both lamps show similar wear.
