Honda Motorcycle CBR1000F high beam and low beam headlight bulbs both use a 9003 size. The replacement chart covers vehicle production years spanning 1987 to 1988.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9003 bulb is an ANSI-standard dual-filament halogen type rated at 12 volts, with a higher-power filament of 60 watts designated for high beam operation and a 55-watt filament for low beam operation, both contained within a single housing.
The 9003 bulb uses a P43t base, which is a bayonet-style mount with a 43mm cap width, a common format in halogen headlight applications across North American markets.
The Honda Motorcycle CBR1000F uses the 9003 bulb for both its high beam and low beam headlight positions across the 1987-1988 model years, meaning a single bulb type serves both functions simultaneously through its dual-filament design.
Because the 9003 specification is defined by ANSI standards applicable to the United States and Canada, its fitment is tied to that regional standard and may not be directly interchangeable with ECE-standard bulbs used in other markets, even when physical dimensions appear similar.
The H4 bulb is the closest international equivalent to the 9003 and shares the same dual-filament configuration and wattage ratings, but the two are not universally considered interchangeable due to differences in base construction and regulatory classification depending on the market.
