Honda Motorcycle VF750F V45 Interceptor uses 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 1983 to 1984 model 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 is an ANSI-standard halogen bulb used in the United States and Canada. It operates on 12 volts and carries a dual-filament design rated at 60 watts for high beam and 55 watts for low beam.
The P43t base is the mounting interface of the 9003 bulb. This base type is a bayonet-style fitting with a 43mm collar, and it determines physical compatibility with the bulb socket.
The Honda Motorcycle VF750F V45 Interceptor uses the 9003 bulb for both the high beam and low beam headlight positions across the 1983-1984 model years.
Because a single 9003 bulb serves both beam functions through its two filaments, the high beam and low beam headlight positions share the same bulb type rather than requiring separate components.
The 9003 shares its filament configuration and base type with the H4 bulb, though the two are not fully interchangeable due to differences in the ANSI and ECE regulatory standards under which each is certified.
