The Ducati Streetfighter high beam and low beam headlight bulbs both utilize a 9003 bulb size. The replacement chart covers vehicle production spanning 2009 to 2015.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9003 bulb type is specified for both the high beam and low beam headlight positions on the Ducati Streetfighter across the 2009-2015 model years.
The 9003 bulb is a dual-filament halogen type, meaning a single bulb contains separate filaments for both high and low beam functions within one housing.
Because the Ducati Streetfighter uses the 9003 for both the high beam and low beam positions, both positions draw from the same bulb standard, which simplifies parts stocking but does not reduce the total number of bulbs required.
The 9003 standard is electrically and physically equivalent to the H4 bulb, a designation more common in European and international markets, making cross-referencing between these two designations relevant when sourcing replacements.
The 9003/H4 bulb operates on a P43t base, which is the standardized three-pronged bayonet-style connector used to seat the bulb within the headlight assembly.
The rated wattage for a standard 9003 bulb is 60 watts on the high beam filament and 55 watts on the low beam filament, drawing power from a 12-volt electrical system.
Aftermarket replacements in formats such as high-output halogen or HID conversion kits are often marketed to fit the 9003/H4 socket, though compatibility with the original housing and wiring is governed by the specific design of the Streetfighter's headlight unit.
The consistent use of the 9003 specification across all listed model years indicates that the headlight assembly design remained unchanged throughout the 2009-2015 production span of the Streetfighter.
