Saturn SL2 front side marker bulbs use 168 and 24 bulb sizes, while rear side marker bulbs require 194 bulb size. The replacement chart covers 1991 to 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 SL2 front side marker uses two different bulb sizes across its production run, with the 168 fitted to 1996-2002 models and the 24 fitted to 1991-1995 models.
The bulb 168 is an ANSI-standard miniature wedge type with a T10 form factor, rated at 12V and 4.9W.
The bulb 24 carries an BA9s bayonet base rather than a wedge base, rated at 12V and 2W, making it physically incompatible with sockets designed for wedge-type bulbs.
The Saturn SL2 rear side marker uses the 194 bulb across all model years from 1991-2002, with no change in specification throughout the entire production run.
The 194 is an ANSI-standard miniature wedge bulb with a T10 form factor, rated at 12V and 3.78W.
Both the 168 and 194 share the T10 wedge form factor, though their wattage ratings differ at 4.9W and 3.78W respectively, meaning they are not direct substitutes despite the shared base type.
All three bulb sizes listed, the 168, 24, and 194, conform to ANSI standards applicable in both the United States and Canada.
The front-to-rear marker bulb fitment on the Saturn SL2 is not uniform for any model year, as the front and rear positions draw from different bulb specifications throughout the full 1991-2002 range.
