Suzuki Motorcycle GSF600 Bandit headlight bulbs utilize 9005 and 9003 sizes for high beam applications, with 9006 and 9003 sizes serving low beam functions. The replacement chart covers 1996 through 2003 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.
The Suzuki Motorcycle GSF600 Bandit uses three distinct halogen bulb types across its headlight positions: the 9005, 9006, and 9003, all of which conform to ANSI standards applicable in the United States and Canada.
The 9003 is a dual-filament halogen bulb rated at 12V with a 60W high beam filament and a 55W low beam filament, mounted on a P43t base. Its dual-filament construction means a single 9003 bulb serves both high and low beam functions within one housing.
The 9005 is a single-filament halogen bulb rated at 12V and 65W, fitted with a P20d base, and is dedicated exclusively to high beam operation. The 9006 is likewise a single-filament halogen bulb rated at 12V and 55W, using a P22d base, and is dedicated exclusively to low beam operation.
On the Suzuki Motorcycle GSF600 Bandit, the 2000-2003 model years use separate 9005 and 9006 bulbs for the high and low beam positions respectively, while the 1996-1999 model years use a single 9003 bulb to handle both beam functions.
The P20d, P22d, and P43t base designations are physically incompatible with one another, meaning the 9005, 9006, and 9003 bulbs are not interchangeable despite sharing the same 12V operating voltage.
Although the 9005 and 9006 are both single-filament bulbs operating on 12V, their differing wattage ratings (65W versus 55W) and distinct base types confirm they are not substitutes for each other across beam positions.
The shift from a dual-filament 9003 arrangement to separate single-filament 9005 and 9006 bulbs between the 1999 and 2000 model years indicates a change in headlight housing design, as the two configurations require physically different lamp assemblies.
