Yamaha YZF-R6 Headlight Bulb Size

The Yamaha YZF-R6 headlight bulb uses H7 and 9003 sizes for both high and low beam functions. The replacement chart covers 1999 to 2016 production 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.

Additional Notes

The H7 is a single-filament halogen bulb operating at 12V and 55W, fitted with a PX26d base. It follows the ECE standard and holds approval for use in Europe, worldwide markets, the United States, and Japan.
The 9003 is a dual-filament halogen bulb operating at 12V with a 60W high beam filament and a 55W low beam filament. It uses a P43t base and follows the ANSI standard applicable to the United States and Canada.
Because the H7 carries a single filament, it serves only one lighting function per bulb. The Yamaha YZF-R6 models from 2003-2016 therefore use one H7 bulb for the high beam and a separate H7 bulb for the low beam.
The 9003 bulb, by contrast, houses both filaments within a single unit, meaning one bulb handles both the high beam and low beam functions on the 1999-2002 YZF-R6.
The PX26d base of the H7 and the P43t base of the 9003 are physically incompatible with each other. These two bulb types are not interchangeable, and the socket design of the headlight housing determines which type fits.
The high beam and low beam positions on the YZF-R6 share the same bulb specification for every model year listed. Whichever bulb type applies to one position also applies to the other in that same year.
A bulb change from the 9003 to the H7 type corresponds to the 2002-2003 model year transition on the YZF-R6, reflecting a shift between two distinct base types and filament configurations.
The H7 specification covers the 2003-2016 model years, making it the bulb type associated with the greater portion of the YZF-R6 production span represented in these specifications.
