Honda Motorcycle CBR650F uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2014 through 2016 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 dual-filament halogen bulb rated at 12 volts, with a high beam filament drawing 60 watts and a low beam filament drawing 55 watts, fitted with a P43t base.
Because the 9003 carries two filaments within a single bulb, it serves both the high beam and low beam functions simultaneously, which is why the Honda Motorcycle CBR650F uses the same bulb size for both headlight positions across its 2014-2016 model years.
The P43t base is a bayonet-style fitting with a 43mm collar, and correct base alignment is required for proper seating in the headlight housing.
The 9003 designation is specific to the ANSI standard used in the United States and Canada. The functionally equivalent bulb sold under European ECE standards carries the designation H4, and while the two types share similar electrical ratings, they are not always interchangeable due to potential differences in base keying and beam pattern certification.
A single 9003 bulb handles the full headlight load on the CBR650F, meaning a failed bulb results in the loss of both high and low beam output at once.
