The Aprilia SL 750 Shiver uses H7 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2008 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 H7 is a single-filament halogen bulb operating at 12 volts and 55 watts, fitted with a PX26d base. The single-filament design means one bulb serves one lighting function, which is why the Aprilia SL 750 Shiver uses separate H7 units for high beam and low beam positions.
The PX26d base is a keyed, two-pin connector that physically prevents incorrect bulb orientation during installation, a feature common to H7 applications across many vehicle platforms.
The H7 bulb follows the ECE (Economic Commission for Europe) standard, giving it approval for road use across Europe, worldwide markets, the United States, and Japan.
Both the 2008-2009 Aprilia SL 750 Shiver model years share identical H7 fitment across all headlight positions, meaning the high beam and low beam bulb type is consistent across this production span.
Because the high beam and low beam positions both use the H7 specification on the SL 750 Shiver, the two housings are not interchangeable by function despite accepting the same bulb type physically.
