The Suzuki Motorcycle VS750GL Intruder uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 1988 to 1991 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 Suzuki Motorcycle VS750GL Intruder uses the 9003 bulb size for both its high beam and low beam headlight positions across the 1988-1991 model years.
The 9003 is an ANSI-standardized bulb designation recognized in the United States and Canada, distinguishing it from region-specific equivalents used in other markets.
As a dual-filament halogen bulb, the 9003 houses two separate tungsten filaments within a single glass envelope, one dedicated to high beam output and one to low beam output.
The 9003 operates on a 12-volt electrical system and carries a wattage rating of 60W on the high beam filament and 55W on the low beam filament.
The 9003 uses a P43t base, which is a standardized bayonet-style mount with a 43mm flange, governing physical fitment into the headlight housing.
Because both the high beam and low beam positions share the same 9003 specification, a single bulb type serves the entire headlight assembly on the VS750GL Intruder.
The 9003 bulb is closely related to the H4 designation used in international markets, though the two are not always interchangeable due to differences in base tolerances and certification standards.
