Saturn SC front and rear side marker bulbs utilize 194 and 168 bulb sizes respectively. The replacement chart covers 1991 to 1992 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 SC uses two bulb types across its side marker positions: the 194 for the front and the 168 for the rear, both covering the 1991-1992 model years.
Both the 194 and 168 are ANSI-standardized bulbs recognized in the United States and Canada, meaning they conform to a defined set of electrical and physical specifications.
Both bulb types share the T10 miniature wedge form factor, a small, wedge-shaped base design that requires no locking mechanism and is retained by socket tension alone.
Both bulbs operate at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles of this era.
The 194 bulb, used in the front side marker position, is rated at 3.78 watts, producing a lower light output relative to the rear position bulb.
The 168 bulb, used in the rear side marker position, carries a higher wattage rating of 4.9 watts, drawing more current than the front marker bulb despite sharing the same T10 base.
Although the 194 and 168 share the T10 wedge base and are physically interchangeable in terms of socket fitment, their wattage ratings differ, and substituting one for the other would alter the intended power draw for that circuit position.
