Suzuki Motorcycle VS1400GL Intruder high beam and low beam headlight bulbs both utilize a 9003 bulb size. The replacement chart covers vehicle production spanning 1987 to 2004.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Suzuki Motorcycle VS1400GL Intruder uses the 9003 bulb for both high beam and low beam headlight positions across all model years from 1987-2004.
The 9003 is an ANSI-standard halogen bulb recognized in the United States and Canada, operating on a 12-volt electrical system with a dual-filament design rated at 60 watts for high beam and 55 watts for low beam.
Because both the high beam and low beam positions share the same 9003 bulb type, a single bulb serves both lighting functions through its two internal filaments rather than requiring separate bulbs for each beam.
The 9003 uses a P43t base, which is a bayonet-style mount with a 43mm collar. This base type determines physical fitment into the headlight housing and is not interchangeable with other base configurations.
The 9003 is functionally equivalent to the European H4 bulb, sharing the same dual-filament halogen construction and P43t base. However, the ANSI 9003 designation applies specifically to the North American market standard.
The consistent use of the 9003 across all eighteen model years means that bulb fitment remains uniform throughout the entire production run of the VS1400GL Intruder as covered by these specifications.
