Yamaha FZ6R front turn signal bulbs measure 7443 in size, while rear turn signal bulbs measure 7440 in size. The replacement chart covers 2009 through 2017 model years 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 FZ6R uses the 7443 bulb for the front turn signal position across all model years from 2009-2017.
The 7443 is a dual-filament T20 wedge bulb rated at 12V with a 21W/5W output, conforming to the ANSI standard used in the US and Canada.
The dual-filament design of the 7443 means it carries two separate circuits within a single housing, allowing it to serve both a primary and a secondary lighting function simultaneously.
The rear turn signal position on the FZ6R calls for the 7440 bulb across all model years from 2009-2017.
The 7440 is a single-filament T20 wedge bulb rated at 12V and 21W, also conforming to the ANSI standard used in the US and Canada.
Both the 7443 and 7440 share the T20 wedge base form factor, which is a common source of fitment confusion. Despite their physical similarity, the 7443 and 7440 are not interchangeable due to the difference in filament count.
Installing a 7440 in a socket designed for a 7443 would result in the loss of the secondary filament function, as the single-filament 7440 cannot replicate the dual-filament behavior of the 7443.
The front and rear turn signal positions on the FZ6R (2009-2017) each require a distinct bulb type, making it necessary to source both the 7443 and 7440 separately when servicing all four turn signal housings.
