The Honda Motorcycle VTR250 Interceptor headlight bulb uses a 9003 size for both high and low beam functions. The replacement chart covers 1988 to 1990 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 is the sole bulb type listed across all headlight positions in the Honda Motorcycle VTR250 Interceptor specifications, covering model years 1988-1990.
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 carries a wattage rating of 60W on the high beam filament and 55W on the low beam filament.
The 9003 uses a P43t base, a standardized bayonet-style fitting that determines physical socket compatibility during replacement.
The 9003 designation follows the ANSI standard applicable to the United States and Canada, which defines the bulb's electrical and physical characteristics within those markets.
The H4 bulb is the international equivalent of the 9003 and shares the same dual-filament halogen design and P43t base, though the two designations originate from different regional standards bodies and may carry slight regulatory differences.
