The Kawasaki KL650B Tengai headlight bulb utilizes a 9003 size for both high and low beam functions. This replacement chart covers 1990 to 1991 production years with corresponding bulb 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 operating at 12 volts, with a 60-watt filament for high beam and a 55-watt filament for low beam. It uses a P43t base and conforms to the ANSI standard applicable in the United States and Canada.
The Kawasaki KL650B Tengai uses the 9003 bulb for both the high beam and low beam headlight positions across the 1990-1991 model years.
Because a single 9003 bulb serves both beam functions through its dual-filament design, the high beam and low beam headlight positions share the same physical bulb rather than requiring separate units.
The 9003 designation is the ANSI classification used in North America. It is functionally equivalent to the H4 bulb type used under international standards, though fitment interchangeability between these designations depends on whether the socket and housing are compatible.
