The Suzuki Motorcycle VS700 Intruder high beam and low beam headlight bulb size is 9003. The replacement chart covers 1986 to 1987 vehicle production years with bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9003 is the sole bulb type listed across all headlight positions for the Suzuki Motorcycle VS700 Intruder, covering both the high beam and low beam functions for the 1986-1987 model years.
The 9003 is a dual-filament halogen bulb, meaning a single physical bulb contains two separate filaments: one rated at 60 watts for high beam output and one rated at 55 watts for low beam output.
Despite the VS700 Intruder having distinct high beam and low beam headlight positions, both positions use the same 9003 bulb specification, indicating the vehicle relies on the filament-switching capability of the bulb rather than separate single-filament units.
The 9003 operates on a 12-volt electrical system, which is standard for motorcycles of this type.
The 9003 uses a P43t base, a bayonet-style mount with a 43mm collar. This base type is specific to the 9003 and its international equivalent, the H4, and is not interchangeable with other common automotive base types such as the P14.5s used by H1 or H7 bulbs.
The 9003 designation is the ANSI standard used in the United States and Canada. The H4 is its functionally equivalent counterpart under ECE regulations used in other markets, and while the two are often cross-compatible, the specification as listed references the 9003 designation specifically.
