The Honda Motorcycle GL1100 Gold Wing uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 1980 to 1983 model 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 Honda Motorcycle GL1100 Gold Wing uses the 9003 bulb size for both the high beam and low beam headlight positions across the 1980-1983 model years.
The 9003 is an ANSI-standardized halogen bulb recognized in the United States and Canada, operating on a 12-volt electrical system with a dual-filament design rated at 60 watts for high beam and 55 watts for low beam.
Because the 9003 contains two filaments within a single housing, one bulb serves both the high and low beam functions, which accounts for its use in both headlight positions on the GL1100 Gold Wing.
The 9003 bulb uses a P43t base, a bayonet-style mount with a 43mm collar, which determines physical socket compatibility and is a critical factor in fitment.
The 9003 and H4 bulb types share the same P43t base and dual-filament halogen construction, making them functionally interchangeable in many applications; however, fitment should be confirmed against the specific socket and housing of the GL1100 Gold Wing before substitution.
