The Aprilia RSV4 RR uses H7 and H8 bulb sizes for both high beam and low beam headlight applications. The replacement chart covers 2016 through 2020 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 bulb is a single-filament halogen type operating at 12V and 55W, fitted with a PX26d base, and recognized under ECE standards with approval also extended to the US and Japan.
The H8 bulb is likewise a single-filament halogen type but operates at a lower wattage of 35W at 12V, uses a PGJ19-1 base, and carries ECE approval along with US approval.
The PX26d base on the H7 and the PGJ19-1 base on the H8 are physically incompatible with each other, meaning the two bulb types are not interchangeable despite both being single-filament halogen designs.
The Aprilia RSV4 RR uses the H7 bulb for both high beam and low beam headlights across the 2017-2020 model years.
The 2016 Aprilia RSV4 RR uses the H8 bulb for both high beam and low beam positions, distinguishing it from all other years in the specification.
Because the 2016 model year uses a different bulb type and base fitting than the 2017-2020 model years, parts sourced for one production period are not directly applicable to the other.
