The Ducati GT1000 uses a 906 bulb size for both front and rear turn signal applications. The replacement chart covers 2007 to 2010 model years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 906 bulb is the sole turn signal bulb type specified for the Ducati GT1000, covering both front and rear positions across the 2007-2010 model years.
The 906 is an ANSI-standardized bulb designation used in the United States and Canada, operating at 12 volts with an 8-watt output.
The 906 belongs to the T10 wedge bulb family, which uses a wedge-shaped base rather than a metal contact pin, allowing the bulb to be held in place by tension within its socket.
Because the same 906 bulb is specified for both front and rear turn signals, a single bulb type services all four turn signal positions on the motorcycle.
The T10 wedge form factor is a miniature bulb size, commonly found in low-current signaling applications such as turn signals and parking lights on motorcycles and automobiles.
At 8 watts, the 906 draws relatively low current compared to higher-wattage automotive signal bulbs, which is consistent with the smaller electrical systems typical of motorcycles.
Substituting a bulb of a different wattage in a turn signal circuit can affect the flash rate of the turn signal relay, as many conventional relays are load-dependent.
The wedge base of the T10 format is not compatible with bayonet-style or indexed-pin sockets, so socket type is a relevant factor when sourcing a replacement for the GT1000.
