The Saab 9-2X front and rear turn signal bulbs both utilize a 7440NA size. The replacement chart covers 2005 to 2006 vehicle production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Saab 9-2X uses the 7440NA bulb for both the front and rear turn signals across the 2005-2006 model years.
The 7440NA is a single-filament wedge bulb, meaning it produces light through one filament and is held in place by the wedge-shaped base rather than a bayonet or screw fitting.
The T20 designation refers to the bulb's form factor, a standardized wedge base size widely used in automotive turn signal and tail light applications.
The 7440NA operates at 12 volts and draws 21 watts, which is a typical power rating for automotive turn signal bulbs intended to meet legal visibility requirements.
The "NA" suffix in the 7440NA designation indicates natural amber glass, meaning the amber color is built into the glass envelope itself rather than achieved through a clear bulb paired with an amber lens.
The 7440NA conforms to ANSI standards applicable in the United States and Canada, indicating the bulb meets regulated performance and safety specifications for those markets.
Because the front and rear turn signals share the same 7440NA bulb, a single bulb type serves all four turn signal positions on the 9-2X.
