The Ducati 749S 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 749S uses the 9005 bulb type for both 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 and designed for high-intensity forward lighting applications.
The 9005 bulb produces a focused, high-output beam, which is why it is commonly assigned to high beam positions in automotive and motorcycle lighting systems.
Its use in the low beam position on the 749S is notable, as the 9005 is more typically found in high beam applications; this reflects a manufacturer-specific fitment choice rather than a universal standard.
Because the same bulb type fills both the high beam and low beam sockets, the two positions are not differentiated by bulb specification on this model.
The 9005 shares a physical base with the 9006, but the two are not interchangeable due to differences in tab placement on the base, which prevent incorrect installation in most housings.
Aftermarket 9005 bulbs are widely produced in halogen, high-output halogen, and HID-conversion variants, though compatibility with the 749S housing depends on the specific product design.
