The Aprilia RST1000 Futura headlight bulb size specifications indicate H7 bulbs for both high beam and low beam applications. The replacement chart covers 2001 through 2005 production years with corresponding bulb size data.
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. Its single filament means a separate bulb is required for each lighting function rather than combining two functions in one unit.
The H7 carries ECE certification, a regulatory standard recognized across Europe and much of the world. It also holds approval in the United States and Japan, giving it broad international acceptance across major automotive markets.
The Aprilia RST1000 Futura uses the H7 bulb for both the high beam and low beam headlight positions across the full 2001-2005 model range, meaning both positions draw from the same bulb specification.
Because both headlight positions share the H7 specification, the same replacement bulb physically fits either socket. However, the two positions serve distinct optical functions and are not interchangeable in terms of installation location without affecting intended beam pattern performance.
The PX26d base is a keyed, single-pin connector with a collar that locks the bulb into its housing at a fixed rotational position. This alignment is critical for halogen headlight bulbs, as the filament position relative to the reflector directly affects beam projection.
