The Saturn SW2 side marker utilizes a 168 bulb size for the exterior lighting system on the vehicle. Data for the specific component covers the range from 1996 through 2001.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Saturn SW2 uses three distinct bulb types across its side marker positions: the 168, the 24, and the 194, all of which conform to ANSI standards recognized in both the United States and Canada.
The 168 bulb is a T10 miniature wedge type rated at 12V and 4.9W. It is the most widely used bulb across the SW2's side marker positions, covering both front and rear locations for the 1996-2001 model years.
The 194 bulb shares the same T10 miniature wedge form factor as the 168 but operates at a lower wattage of 3.78W at 12V. Despite the physical similarity, the two are not the same specification and are not listed as interchangeable in these fitment data.
The 24 bulb differs fundamentally from the other two types. It uses a BA9s base rather than a wedge-style base, operates at 12V, and draws only 2W, making it the lowest-wattage bulb in the SW2's side marker fitment data.
For the Saturn SW2, the front side marker position transitioned from the 24 bulb in 1993-1995 to the 168 bulb starting in 1996, a change that persisted through the final model year of 2001.
The rear side marker position used the 194 bulb during 1993-1995 and shifted to the 168 bulb from 1996 onward through 2001.
Because the 168 and 194 share a T10 wedge base, physical installation may be possible in either socket, but the wattage difference means they are not listed as equivalent replacements in this fitment data.
The BA9s base on the 24 bulb is a bayonet-style single-pin cap, which is physically incompatible with the wedge-style sockets used by the 168 and 194 bulbs, ruling out any cross-substitution between the 24 and the other two types.
