The Aprilia ETV 1000 Caponord uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2001 to 2007 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 9003 is the sole bulb type specified across all headlight positions for the Aprilia ETV 1000 Caponord, covering model years 2001-2007.
The 9003 is a dual-filament halogen bulb, meaning a single unit contains two separate filaments to handle both high and low beam functions independently.
The Aprilia ETV 1000 Caponord uses the same 9003 bulb for both its high beam and low beam headlight positions across all listed years.
The 9003 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 width, and this base type governs physical fitment into the headlight housing.
The 9003 is an ANSI-standardized bulb designation used in the United States and Canada, and it is electrically and mechanically equivalent to the European HB2 designation.
Because the 9003 serves both beam functions in this application, substituting a single-filament bulb of a similar type would not replicate the full intended functionality of the headlight assembly.
