Honda Motorcycle CRF250L uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2013 to 2020 production 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 the sole bulb type specified across all headlight positions on the Honda Motorcycle CRF250L, covering both high beam and low beam functions for the 2013-2020 model years.
The 9003 is an ANSI-standard designation recognized in the United States and Canada, making it a regionally specific classification rather than a universal international standard.
As a dual-filament halogen bulb, the 9003 houses two separate filaments within a single envelope, which allows it to serve both high and low beam functions from one unit.
The 9003 operates on a 12-volt electrical system and carries a wattage rating of 60W for the high beam filament and 55W for the low beam filament.
The 9003 uses a P43t base, a bayonet-style mount with a 43mm flange, which physically determines socket compatibility and is a critical factor in fitment.
The 9003 is electrically and physically equivalent to the H4 bulb used under international IEC standards; however, the two designations originate from different standardization systems, and substitution depends on socket and housing compatibility in a given application.
Because the same 9003 bulb serves both the high beam and low beam positions on the Honda Motorcycle CRF250L, the motorcycle uses a single-bulb headlight housing rather than separate bulbs for each function.
