The Harley-Davidson VRSCB V-Rod headlight bulb uses a 9003 size for both high beam and low beam functions. The replacement chart covers 2004 to 2005 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 9003 is the sole bulb type listed across all headlight positions for the Harley-Davidson VRSCB V-Rod, covering both the high beam and low beam functions for the 2004-2005 model years.
The 9003 is a dual-filament halogen bulb, meaning a single physical unit contains separate filaments for two distinct light output levels rather than requiring two separate bulbs.
The bulb operates on a 12-volt electrical system and carries a wattage rating of 60W on the high beam filament and 55W on the low beam filament.
The 9003 uses a P43t base, which is a bayonet-style mount with a 43mm flange. This base type determines physical fitment into the headlight housing.
The 9003 designation follows the ANSI standard used in the United States and Canada. This classification system governs the bulb's electrical and optical performance requirements.
Because the same 9003 bulb specification applies to both the high beam and low beam positions, the VRSCB V-Rod headlight assembly relies on the dual-filament design of that single bulb type to serve both functions from one housing.
