Additional Notes

The H7 bulb follows the ECE standard and is recognized across Europe, the US, and Japan. It is a single-filament halogen type with a PX26d base, rated at 12V and 55W.
The H3 bulb also follows the ECE standard with the same 12V, 55W rating as the H7, but uses a PK22s base rather than a PX26d base, making the two types physically incompatible with each other despite sharing identical wattage.
The 9003 bulb follows the ANSI standard used in the US and Canada. Unlike the H7 and H3, it carries a dual-filament design with a P43t base, rated at 12V with 60W on the high beam filament and 55W on the low beam filament.
On the Aprilia RSV Mille, the high beam headlight used the H3 bulb from 1998-2000, then transitioned to the H7 bulb from 2001-2004. These two bulb types use different base fittings and are not interchangeable.
The low beam headlight on the RSV Mille used the 9003 bulb from 1998-2003. The 9003 is a dual-filament bulb, while the H7 that replaced it in 2004 is single-filament, meaning the socket and wiring configuration for the low beam also changed between those model years.
For the 2004 model year, both the high beam and low beam headlights on the RSV Mille use the H7 bulb, making it the only year in the listed range where a single bulb type covers both functions.
The 9003 bulb's P43t base is physically distinct from both the PX26d base of the H7 and the PK22s base of the H3, meaning no cross-substitution is possible among the three bulb types without modification.
