The Ducati 999R high beam and low beam headlight bulbs both utilize a 9005 size. The replacement chart covers vehicle production spanning 2003 to 2006.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Ducati 999R uses the 9005 bulb type for both its high beam and low beam headlight positions across the 2003-2006 model years.
The 9005 is a single-filament halogen bulb operating at 65 watts, belonging to the P20d base family, which is a standard designation in the automotive and motorcycle lighting industry.
Because the 999R shares the same 9005 specification for both beam positions, the high beam and low beam sockets accept physically identical bulbs.
The 9005 bulb produces a high-intensity output relative to lower-wattage halogen types, which reflects its common use in high beam applications where maximum forward illumination is prioritized.
Although the 9005 and the closely related 9006 bulb share a similar physical form, they use different base configurations and are not interchangeable; the 9006 is keyed differently to prevent incorrect installation.
The consistent 9005 fitment across all four model years of the 999R means that replacement bulbs sourced for any year within the 2003-2006 range are compatible with the others.
