The Suzuki Motorcycle RF900 headlight uses a 9003 bulb size for both high beam and low beam functions. The replacement chart covers vehicle production years spanning 1994 to 1997.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9003 bulb is the sole headlight bulb type listed for the Suzuki Motorcycle RF900 across all documented model years.
The 9003 is an ANSI-standard designation used in the United States and Canada for a dual-filament halogen bulb with a P43t base, rated at 12 volts and drawing 60 watts on the high beam filament and 55 watts on the low beam filament.
The Suzuki Motorcycle RF900 (1994-1997) uses the same 9003 bulb for both the high beam and low beam headlight positions, meaning a single bulb type serves both lighting functions through its two filaments.
The P43t base is a bayonet-style mount with a 43mm flange, which physically determines whether a replacement bulb will seat correctly in the headlight housing.
The 9003 designation is functionally equivalent to the HB2 designation used in international markets, and bulbs sold under either designation share the same base, voltage, and wattage ratings.
Because the 9003 is a dual-filament bulb, a single failure can affect either the high beam or low beam output depending on which filament burns out, while the other filament may remain operational.
