Honda Motorcycle CMX250C Rebel uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2001 to 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 Honda Motorcycle CMX250C Rebel uses the 9003 bulb size for both high beam and low beam headlight positions across all listed model years from 2001-2016, with the exception of 2010 and 2011, which are not present in the specifications.
The 9003 is an ANSI-standard halogen bulb recognized in the United States and Canada, operating on a 12-volt electrical system with a dual-filament design rated at 60 watts for high beam and 55 watts for low beam.
Because the 9003 contains both filaments within a single bulb, it serves both the high beam and low beam headlight positions simultaneously, which accounts for its identical fitment across both sub-parts in the specifications.
The 9003 uses a P43t base, a bayonet-style mount with a 43mm collar, and this base type is a defining fitment characteristic that determines physical compatibility with the headlight housing.
The 9003 bulb is functionally interchangeable with the H4 bulb, as both share the same dual-filament halogen construction, P43t base, and 60W/55W ratings, though the 9003 designation follows ANSI naming conventions while H4 follows ECE standards used in other markets.
Substituting a single-filament bulb in place of the 9003 would result in the loss of either high beam or low beam function, since the dual-filament design is integral to how the headlight system operates on the CMX250C Rebel.
