The Suzuki Motorcycle GSX-S1000F headlight bulb uses an H7 size for both high and low beam functions. The replacement chart covers 2016 to 2018 production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H7 is a single-filament halogen bulb operating at 12 volts and 55 watts, fitted with a PX26d base, which is a two-pin bayonet-style connector designed to lock the bulb securely into its housing.
The H7 bulb type is standardized under ECE regulations, making it approved for road use across Europe, worldwide markets, the United States, and Japan.
The Suzuki Motorcycle GSX-S1000F uses the H7 bulb for both the high beam and low beam headlight positions across the 2016-2018 model years.
Because both beam positions share the same H7 specification, the two housings use physically identical bulbs, though the positions themselves serve distinct optical functions and are not interchangeable as installed units.
The single-filament construction of the H7 means each bulb produces only one light output level, which is why separate bulbs are required for high and low beam functions rather than a single dual-filament unit.
At 55 watts, the H7 falls within the standard wattage range for halogen headlight bulbs, a figure regulated under ECE standards to maintain consistent luminous output and prevent excessive heat generation within the housing.
