The Yamaha VX800 VMAX-4 800 headlight bulb uses a 9003 size for both high beam and low beam applications. The replacement chart covers 1995 to 1997 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 listed across all headlight positions in the Yamaha VX800 VMAX-4 800 specifications for the 1995-1997 model years.
The 9003 is a dual-filament halogen bulb, meaning a single unit contains separate filaments for both high and low beam operation, which accounts for its use in both headlight positions.
The 9003 operates on a 12-volt electrical system and draws 60 watts on the high beam filament and 55 watts on the low beam filament.
The 9003 follows the ANSI standard recognized in the United States and Canada, and it uses a P43t base, which is a bayonet-style mount with a 43mm flange.
The 9003 and H4 bulbs share the same dual-filament halogen construction and P43t base, making them functionally interchangeable in many applications; however, fitment should be confirmed against the specific socket and housing before substitution.
