The Kawasaki KLX250 high beam and low beam headlight bulbs both utilize a 9003 size. The replacement chart covers vehicle production spanning 2006 to 2020.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Kawasaki KLX250 uses the 9003 bulb size for both high beam and low beam headlight positions across all listed model years from 2006 to 2020.
The 9003 is an ANSI-standard designation recognized in the United States and Canada, making it the North American equivalent of the internationally designated H4 bulb.
The 9003 is a dual-filament halogen bulb, meaning a single unit contains two separate filaments that serve both the high beam and low beam functions within one housing.
The bulb 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 three-pronged bayonet-style mount that physically locks the bulb into the headlight housing at a fixed rotational position to maintain correct filament alignment.
Because both beam positions share the same bulb type, only one replacement part is required to service either headlight function on the KLX250.
The listed model years are not consecutive, with gaps present between certain years such as 2014 and 2018, though the 9003 specification remains the same across all entries in the data.
