The Saab 9000 side marker utilizes a 12961 bulb size for illumination purposes within the exterior lighting assembly. Data for the specified component covers the range from 1996 through 1998.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Saab 9000 front side marker uses two distinct bulb types across its production run: the 3893 for model years 1996-1998 and the P21/5W for model years 1986-1992.
Both the 3893 and P21/5W share the BAY15d bayonet base, a two-pin offset base design that physically locks the bulb into position and prevents incorrect insertion.
Both bulbs operate on 12V and carry dual filaments, meaning each contains two separate light-producing elements within a single envelope.
The 3893 is classified under the ANSI standard, the regulatory framework governing bulb specifications in the United States and Canada.
The P21/5W is classified under the ECE standard, the regulatory framework used across Europe and much of the rest of the world, and carries a rated output of 21W on its primary filament and 5W on its secondary filament.
Despite sharing the BAY15d base, the 3893 and P21/5W originate from different standardization systems, and substitution between them warrants verification of wattage and filament compatibility before fitment.
The Saab 9000 rear side marker, covering model years 1996-1998, uses the P21/5W exclusively.
For model years 1996-1998, the front and rear side markers of the Saab 9000 use different bulb types, with the front position calling for the 3893 and the rear position calling for the P21/5W.
