The Kawasaki ZR1100 headlight bulb uses a 9003 size for both high beam and low beam applications. The replacement chart covers 1992 to 1995 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 Kawasaki ZR1100 uses the 9003 bulb for both high beam and low beam headlight positions across the 1992-1995 model years.
The 9003 is an ANSI-standard designation recognized in the United States and Canada, making it the North American equivalent of what is internationally classified as the H4 bulb type.
As a dual-filament halogen bulb, the 9003 houses two separate tungsten filaments within a single glass envelope, with one filament dedicated to high beam output and the other to low beam output.
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 P43t base is a bayonet-style mount with a 43mm flange, which physically locks the bulb into the headlight housing and aligns the filaments with the reflector optics.
Because both the high beam and low beam positions share the same 9003 specification, a single bulb type serves the entire headlight assembly rather than requiring separate bulbs for each function.
The shared fitment across all four model years means a 9003 bulb sourced for a 1992 ZR1100 is interchangeable with those required for the 1993-1995 model years without modification.
