Honda Motorcycle GL1500CT Valkyrie Tour Headlight Bulb Size
Honda Motorcycle GL1500CT Valkyrie Tour high beam and low beam headlight bulbs both utilize 9003 size bulbs for optimal illumination. The replacement chart covers 1997 to 2000 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 Honda Motorcycle GL1500CT Valkyrie Tour uses the 9003 bulb for both the high beam and low beam headlight positions across the 1997-2000 model years.
The 9003 is an ANSI-designated bulb standard recognized in the United States and Canada, distinguishing it from its international equivalent, the H4, which shares the same physical and electrical characteristics but carries a different designation.
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 bulb operates on a 12-volt electrical system, consistent with standard 12V motorcycle electrical architecture.
The 9003 uses a P43t base, which is a three-pronged bayonet-style mount. This base type is specific to dual-filament headlight bulbs and is not interchangeable with single-filament base types such as P14.5s or P15d.
Because the same 9003 bulb size is specified for both the high beam and low beam positions, the GL1500CT Valkyrie Tour uses a single bulb to serve both functions rather than separate bulbs for each beam.
