Saturn SC2 front side marker bulbs use 168, 24, or 194 size configurations, while rear side marker bulbs use 194 or 168 size options. The replacement chart covers 1993 through 2002 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 Saturn SC2 uses three distinct bulb types across its side marker positions: the 168, the 194, and the 24.
Both the 168 and 194 are ANSI-standard miniature wedge bulbs sharing the T10 form factor and a 12V operating voltage, though they differ in wattage. The 168 draws 4.9W while the 194 draws 3.78W.
Because the 168 and 194 share the same T10 wedge base, they are physically interchangeable in terms of socket fit, but their wattage ratings differ, which affects light output.
The bulb designated 24 is an ANSI-standard single-filament bulb with a BA9s base, rated at 12V and 2W. The BA9s is a bayonet-style cap with a 9mm collar, which is a different socket type from the T10 wedge used by the 168 and 194, making it non-interchangeable with those two types.
For the Saturn SC2 front side marker, the 168 bulb was specified for the 1997-2002 model years, the 24 bulb for 1996, and the 194 bulb for 1993-1995.
For the rear side marker, the 194 bulb was specified for 1997-2002, while the 168 bulb was specified for 1993-1996.
In 1996, the Saturn SC2 used opposite bulb types between its front and rear side markers. The front used the 24 and the rear used the 168, meaning no single bulb type served both positions that year.
From 1997 onward through 2002, the front and rear side marker positions also used different bulb types from each other, with the 168 at the front and the 194 at the rear.
