The Yamaha FZ-09 high beam and low beam headlight bulbs both utilize a 9003 size. The replacement chart covers vehicle production years spanning 2014 to 2016.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9003 bulb is the sole bulb type specified across all headlight positions on the Yamaha FZ-09 for the 2014-2016 model years.
The 9003 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments: one rated at 60W for high beam operation and one rated at 55W for low beam operation.
Because the 9003 is dual-filament, it serves both the high beam and low beam headlight positions simultaneously, which accounts for its appearance in both sub-parts of the specification.
The 9003 operates on a 12V electrical system and uses a P43t base, which is a bayonet-style mount with a 43mm flange.
The 9003 designation follows the ANSI standard used in the United States and Canada, making it a regionally defined specification rather than a universal international one.
The P43t base is not interchangeable with other common halogen base types such as H4, despite the H4 sharing a similar dual-filament design and wattage rating. Physical base differences prevent cross-fitment.
