The Yamaha VX700 VMAX 700 headlight bulb uses a 9003 size for both high and low beam functions. Replacement bulb specifications are documented in a chart covering 1997 to 2001 production years.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Yamaha VX700 VMAX 700 uses the 9003 bulb size for both the high beam and low beam headlight positions across the 1997-2001 model years.
The 9003 is an ANSI-standard bulb recognized in the United States and Canada, operating on a 12-volt electrical system with a dual-filament halogen design rated at 60 watts for high beam and 55 watts for low beam.
Because a single 9003 bulb serves both beam functions through its two filaments, one physical bulb handles the full headlight output for each position rather than requiring separate single-filament units.
The 9003 bulb uses a P43t base, which is a bayonet-style mount with a 43mm collar. This base type determines physical fitment and is not interchangeable with other base configurations regardless of voltage or wattage similarity.
The 9003 and H4 bulbs share the same dual-filament halogen construction and P43t base, making them functionally equivalent in most applications. However, fitment should be confirmed against the listed specification before substitution.
