The Aprilia Tuono V4 R APRC headlight bulb uses an H7 size for both high beam and low beam applications. The replacement chart covers 2012 to 2014 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 H7 is a single-filament halogen bulb operating at 12 volts and 55 watts, fitted with a PX26d base, which is a two-pin bayonet-style connector designed to secure the bulb in a fixed rotational position within the housing.
The H7 bulb is rated under the ECE standard, giving it approval for use across Europe and most worldwide markets, as well as in the United States and Japan.
The Aprilia Tuono V4 R APRC uses the H7 bulb for both the high beam and low beam headlight positions across the 2012-2014 model years.
Because both beam positions share the same H7 specification, the two housings accept physically identical bulbs, though the optical assemblies themselves are distinct and the bulbs are not interchangeable between positions during installation.
The single-filament design of the H7 means each bulb serves only one lighting function, which is why separate units are required for high and low beam duties rather than a dual-filament alternative.
