Honda Motorcycle CBR250R uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2011 to 2013 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 a dual-filament halogen bulb, meaning a single unit contains two separate filaments: one rated at 60W for high beam operation and one rated at 55W for low beam operation.
The 9003 operates on a 12-volt electrical system and uses a P43t base, which is a bayonet-style mount with a 43mm flange.
The 9003 designation follows the ANSI standard used in the United States and Canada, making it a regionally defined specification rather than a universal global standard.
The Honda Motorcycle CBR250R uses the 9003 bulb for both the high beam and low beam headlight positions across the 2011-2013 model years.
Because both beam positions share the same 9003 bulb type, a single filament failure does not require a different replacement part for each function; however, the dual-filament design means one filament can fail independently of the other within the same bulb.
The 9003 is functionally equivalent to the HB2 designation used in some international markets, though fitment should be confirmed against the P43t base specification before substitution.
