Honda Motorcycle GL1500C/CD Valkyrie headlight bulbs utilize a 9003 size for both high and low beam functions. The replacement chart covers 1997 to 2003 model 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 bulb is the sole bulb type specified for the Honda Motorcycle GL1500C/CD Valkyrie across both the high beam and low beam headlight positions for the 1997-2003 model years.
The 9003 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments: one rated at 60 watts for high beam output and one rated at 55 watts for low beam output.
The 9003 operates on a 12-volt electrical system, which is standard for motorcycle applications in this class.
The 9003 uses a P43t base, a bayonet-style mount with a 43mm collar that physically locks the bulb into the headlight housing.
The 9003 is an ANSI-standardized bulb recognized in both the United States and Canada, meaning it conforms to a defined set of electrical and physical specifications shared across manufacturers.
Because the GL1500C/CD Valkyrie uses the same 9003 bulb for both the high beam and low beam positions, a single replacement bulb type serves both functions on this motorcycle.
The 9003 bulb is also commonly cross-referenced with the H4 designation used in international markets, though fitment should be confirmed against the P43t base specification before substitution.
