The Yamaha YZF600R headlight bulb uses a 9003 and HS1 size for both high beam and low beam functions. The replacement chart covers vehicle production years spanning 1995 to 2007 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 YZF600R uses two distinct headlight bulb types across its production span: the 9003 and the HS1. Both are dual-filament halogen bulbs operating on a 12V system, meaning each handles both high and low beam functions within a single unit.
The 9003 is an ANSI-standard bulb used in the United States and Canada. It carries a P43t base and is rated at 60W on the high beam filament and 55W on the low beam filament.
The HS1 follows the ECE standard used in Europe and other international markets. It uses a PX43t base and runs both filaments at 35W, resulting in a notably lower wattage output than the 9003.
Although the 9003 and HS1 share a similar physical base size, the P43t and PX43t bases are not interchangeable. The PX43t base on the HS1 includes a locating tab that differs from the P43t base on the 9003, preventing cross-installation between the two types.
The Yamaha YZF600R (1997-2007) uses the 9003 bulb for both the high beam and low beam headlight positions.
The 1995-1996 model years use the HS1 bulb for both headlight positions, reflecting a different electrical and optical specification from the later production years.
Because the 9003 and HS1 differ in both wattage and base design, a bulb sourced for a 1997-2007 model is not a direct physical or electrical match for a 1995-1996 model, and the reverse is equally true.
