The Yamaha FZS600 FZ6 uses an H7 bulb size for high beam headlight operation and a 9003 bulb size for low beam headlight operation. The replacement chart covers vehicle production years spanning 2004 to 2009 with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Yamaha FZS600 FZ6 uses two distinct bulb types across its headlight system: the H7 for the high beam and the 9003 for the low beam, covering the 2004-2009 model years for both positions.
The H7 is a single-filament halogen bulb operating at 12V and 55W, fitted with a PX26d base. Its single filament means it is dedicated to one lighting function only, which is why a separate bulb handles the high beam role on this motorcycle.
The 9003 is a dual-filament halogen bulb rated at 12V with a 60W filament for high beam and a 55W filament for low beam. Despite carrying both filaments, it is used exclusively in the low beam position on the FZS600 FZ6.
The H7 follows the ECE standard, which governs lighting equipment across Europe and much of the world. It also carries approval in the United States and Japan, giving it broad international acceptance.
The 9003 follows the ANSI standard, which is the governing specification used in the United States and Canada. The 9003 and the European HB2 designation refer to the same physical bulb under different standardization systems.
The H7 uses a PX26d base, while the 9003 uses a P43t base. These two base types are physically incompatible with each other, meaning the high beam and low beam sockets on the FZS600 FZ6 are not interchangeable.
Because the H7 and 9003 have different base configurations and wattage ratings, substituting one for the other in either socket is not supported by the specifications for this motorcycle.
