The Yamaha VX750 VMAX-4 high beam and low beam headlight bulbs both utilize a 9003 size. The replacement chart covers 1992 to 1994 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 for the Yamaha VX750 VMAX-4 across all listed headlight positions and model years.
The 9003 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments: one rated at 60W for high beam operation and one rated at 55W for low beam operation.
Because the 9003 serves both the high beam and low beam headlight positions on this vehicle, a single bulb type handles the full range of forward lighting functions.
The 9003 operates on a 12V electrical system, which is standard for most automotive and powersports applications of its era.
The bulb uses a P43t base, a standardized bayonet-style mount that determines physical fitment into the headlight housing.
The 9003 designation follows the ANSI standard used in the United States and Canada. It is functionally equivalent to the international HB2 designation, though the two designations originate from different standardization bodies and packaging differences may exist.
The Yamaha VX750 VMAX-4 carries the 9003 specification across the 1992-1994 model years without variation in either beam position.
The P43t base is not universally interchangeable with other common halogen base types such as H4 or 9004, despite those bulbs also being dual-filament designs, so substitution requires confirmation of base compatibility before installation.
