The Kawasaki KLR250 high beam and low beam headlight both utilize a 9003 bulb size. The replacement chart covers vehicle production spanning 1985 to 2005.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Kawasaki KLR250 uses the 9003 bulb for both high beam and low beam headlight positions across all model years from 1985-2005.
The 9003 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments to serve both the high and low beam functions within one housing.
The 9003 operates on a 12-volt electrical system and draws 60 watts on the high beam filament and 55 watts on the low beam filament.
The 9003 uses a P43t base, which is a bayonet-style mount with a 43mm collar, and this base type determines physical fitment into the headlight housing.
The 9003 designation follows the ANSI standard used in the United States and Canada, and it is interchangeable with the HB2 designation used in those markets.
The H4 bulb, common in international markets, shares the same dual-filament halogen design and P43t base as the 9003, though the 9003 and H4 designations reflect different regional standards and wattage ratings, which can affect direct interchangeability.
