The Kawasaki KXF250 Tecate 4 headlight bulb uses a 9003 size for both high beam and low beam applications. The replacement chart covers vehicle production years spanning 1987 to 1988.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9003 bulb is the sole bulb type listed across all headlight positions in the Kawasaki KXF250 Tecate 4 specifications, covering both the high beam and low beam headlight positions for 1987-1988.
The 9003 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments: one rated at 60W for high beam output and one rated at 55W for low beam output.
The 9003 operates on a 12V electrical system, which is standard for this class of halogen automotive and powersports lighting.
The 9003 uses a P43t base, a bayonet-style fitting that locks the bulb into the housing through a twist-and-seat motion rather than a screw thread.
The 9003 is designated as an ANSI standard bulb, meaning its specifications are governed by the American National Standards Institute and the equivalent Canadian standards body, establishing consistent performance and fitment requirements across manufacturers.
Because the 9003 is a dual-filament bulb serving both beam functions, the high beam and low beam headlight positions in the Kawasaki KXF250 Tecate 4 share an identical bulb specification across both listed model years.
The 9003 and H4 bulb types are functionally equivalent in electrical and optical output, but they differ in base configuration, and substitution between the two requires confirmation of housing compatibility before use.
