The Yamaha FJ1200 headlight bulb uses a 9003 size for both high and low beam functions. The replacement chart covers 1986 to 1993 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 Yamaha FJ1200 uses the 9003 bulb for both high beam and low beam headlight functions across the 1986-1993 model range.
The 9003 is a dual-filament halogen bulb, meaning a single unit contains separate filaments for high and low beam output, which is why it serves both headlight positions on this motorcycle.
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 is built to the ANSI standard and is recognized in both the United States and Canada under that designation.
The bulb uses a P43t base, which is a bayonet-style mount with a 43mm collar. This base type is specific to the 9003 and related international equivalents such as the H4.
The 9003 and H4 share the same physical construction and are widely regarded as interchangeable, though the 9003 designation reflects the North American ANSI classification while H4 reflects the ECE standard used in other markets.
Because the same bulb size applies to both the high beam and low beam positions on the Yamaha FJ1200, only one bulb type is required to service either headlight function.
