Saturn SL front side marker bulbs use 168 and 24 bulb sizes, while rear side marker bulbs require 194 bulb size specifications. The replacement chart covers vehicle production years spanning 1991 to 2002.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Saturn SL front side marker uses two different bulb sizes depending on the model year. The 1991-1995 model years require a size 24 bulb, while the 1996-2002 model years require a size 168 bulb.
The size 24 bulb is an ANSI-standard single-filament type with a BA9s bayonet base, rated at 12V and 2W. The BA9s base is a small single-pin bayonet fitting, which is physically incompatible with the wedge-style socket used by the size 168 bulb.
The size 168 is an ANSI-standard miniature wedge bulb of the T10 form factor, rated at 12V and 4.9W. Its wedge base is held in place by tension rather than a locking pin, which is a fundamentally different retention method than the BA9s base of the size 24.
Because the size 24 and size 168 bulbs use incompatible base types, they are not interchangeable across the 1991-1995 and 1996-2002 front side marker positions on the Saturn SL.
The rear side marker on the Saturn SL uses a size 194 bulb across all model years from 1991-2002, with no change in specification over the entire production run covered by these data.
The size 194 is an ANSI-standard miniature wedge bulb also classified as T10, rated at 12V and 3.78W. It shares the same T10 wedge form factor as the size 168 but operates at a lower wattage.
Although the size 168 and size 194 are both T10 wedge bulbs, their wattage ratings differ at 4.9W and 3.78W respectively. Physical fitment may be possible between the two, but the electrical load characteristics are not identical.
All three bulb sizes listed in these specifications, the 168, 24, and 194, conform to ANSI standards recognized in both the United States and Canada.
