The Suzuki Motorcycle GSF1250 Bandit uses H7 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2007 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.
The H7 is the sole bulb type specified across all listed model years of the Suzuki Motorcycle GSF1250 Bandit, serving both the high beam and low beam headlight positions.
The H7 is a single-filament halogen bulb, meaning each lamp housing requires a dedicated bulb for each beam function rather than a dual-filament unit handling both from a single source.
H7 bulbs use a PX26d base, a two-pin connector with a plastic collar that locks into the housing, distinguishing it from physically similar types such as the H1 or H4.
The H7 operates at 12 volts and 55 watts, values consistent with standard motorcycle electrical systems and typical halogen output levels.
The H7 carries ECE certification, the regulatory standard applied across Europe and much of the world, and holds additional approval in the United States and Japan.
Because both the high beam and low beam positions share the same H7 specification across the 2007-2009 and 2016 model years, the same bulb part number is applicable to either socket on the motorcycle.
The physical and electrical identity of the high beam and low beam bulbs means a bulb installed in one position is interchangeable with one from the other position, provided it is a genuine H7 type with a PX26d base.
