Saturn SC1 front side marker bulbs use 168 or 24 size configurations, while rear side marker bulbs use 194 or 168 size options. The replacement chart covers 1993 through 2002 production 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 Saturn SC1 uses three distinct bulb types across its front and rear side marker positions: the 168, 194, and 24.
The 168 and 194 are both T10 miniature wedge bulbs operating at 12V, though they differ in wattage. The 168 draws 4.9W while the 194 draws 3.78W, making them electrically non-equivalent despite sharing the same physical base format.
Because the 168 and 194 share the T10 wedge base, they are physically interchangeable in terms of fitment, but the wattage difference means substituting one for the other will alter light output and may affect circuit load.
The 24 bulb uses a BA9s base, a single-contact bayonet fitting, which is physically incompatible with the T10 wedge sockets used by the 168 and 194. No cross-substitution between the 24 and the T10 bulbs is possible without socket modification.
The 24 bulb operates at 12V and 2W, making it the lowest-wattage bulb among the three types specified for the Saturn SC1 side marker positions.
All three bulb types conform to ANSI standards applicable in both the United States and Canada.
For the Saturn SC1, the front side marker position transitioned from the 24 bulb in 1993-1996 to the 168 bulb in 1997-2002, representing a change in both base type and wattage for that position.
The rear side marker position on the SC1 used the 168 bulb in 1993-1996 and shifted to the 194 bulb in 1997-2002. Both are T10 wedge types, but the wattage differs between the two periods.
