Suzuki Motorcycle GV1400 Cavalcade headlight bulbs utilize a 9003 size for both high and low beam functions. The replacement chart covers 1986 through 1989 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 9003 bulb is the sole bulb type specified across all headlight positions on the Suzuki Motorcycle GV1400 Cavalcade, covering both high beam and low beam functions for the 1986-1989 model years.
The 9003 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments within one housing, one rated at 60 watts for high beam output and one at 55 watts for low beam output.
Because both the high beam and low beam positions share the same 9003 specification, the GV1400 Cavalcade uses a single bulb per headlight assembly to serve both lighting functions rather than separate dedicated bulbs for each beam.
The 9003 bulb operates on a 12-volt electrical system, which is standard for motorcycle applications of this type.
The 9003 designation follows the ANSI standard used in the United States and Canada, and the bulb uses a P43t base, which is the physical connector type that locks the bulb into the headlight housing.
The 9003 and H4 bulbs share the same dual-filament halogen design and P43t base, making them functionally interchangeable in many applications, though the 9003 designation reflects the North American ANSI classification while H4 reflects the European ECE classification for the same bulb type.
