Honda Motorcycle CBR900RR headlight bulbs utilize a 9003 size for both high and low beam functions. The replacement chart covers 1992 to 1994 production years with corresponding bulb 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 an ANSI-standard halogen type recognized in the United States and Canada, operating at 12 volts with a dual-filament design rated at 60 watts on the high beam filament and 55 watts on the low beam filament.
The P43t base is the mounting interface of the 9003 bulb, a standardized bayonet-style fitting that determines physical compatibility with a given headlight housing.
Because the 9003 uses a dual-filament construction, a single bulb serves both high and low beam functions within one housing rather than requiring separate bulbs for each beam mode.
The Honda Motorcycle CBR900RR uses the 9003 bulb for both its high beam and low beam headlight positions across the 1992-1994 model years.
The 9003 is functionally equivalent to the H4 bulb used in international markets, though the two designations reflect different regional standards and may carry minor specification differences that affect direct interchangeability.
The consistent use of the 9003 across all three model years and both beam positions means a single bulb type covers the full headlight assembly of the CBR900RR for that production span.
