The Aprilia RSV4 Factory uses H11 bulb size for both high beam and low beam headlight applications. The replacement chart covers vehicle production years spanning 2010 to 2015 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 H11 is a single-filament halogen bulb operating at 12 volts and 55 watts, fitted with a PGJ19-2 base. Its single filament means it serves one lighting function per socket rather than combining two functions in one unit.
The H11 carries ECE certification, a regulatory standard recognized across Europe and numerous other markets worldwide, and also holds approval for use in the United States.
Both the high beam and low beam positions on the Aprilia RSV4 Factory use the H11 bulb across the 2010-2015 model years, meaning the same bulb type occupies all four headlight sockets on the motorcycle.
Although the high beam and low beam sockets accept the same H11 bulb type, the two circuits remain electrically separate and serve distinct functions, so a bulb installed in one position does not substitute for the other during operation.
The PGJ19-2 base is a keyed, push-and-twist fitting specific to the H11 and a small number of related halogen types. Its physical design prevents direct installation of bulbs from unrelated base families.
The H11 shares its PGJ19-2 base with closely related types such as the H8 and H9, but those variants differ in wattage and lumen output. Substituting them in place of the specified H11 would alter the electrical load and light output from the factory-intended values.
