Honda Motorcycle VTX1300R/S/T headlight bulbs utilize a 9003 size for both high and low beam functions. The replacement chart covers 2003 to 2009 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 VTX1300R/S/T uses the 9003 bulb for both high beam and low beam headlight positions across the full 2003-2009 model range.
The 9003 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments to serve both high and low beam functions within one housing.
The 9003 operates at 12 volts, with the high beam filament rated at 60 watts and the low beam filament rated at 55 watts.
The 9003 uses a P43t base, which is a standardized bayonet-style mount that determines physical fitment into the headlight socket.
The 9003 is an ANSI-standard designation used in the United States and Canada. It is functionally equivalent to the H4 bulb used in international markets, though the two designations reflect different regional standards and may carry minor specification differences.
Because the same 9003 bulb serves both the high beam and low beam positions on the VTX1300R/S/T, only one bulb type is required to service the entire headlight assembly.
