The Saturn Sky front side marker uses a 194 bulb size while the rear side marker requires a 168 bulb size. The replacement chart covers 2007 to 2010 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 Sky uses two distinct bulb sizes for its side markers across the 2007-2010 model years: the 194 for the front and the 168 for the rear.
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 rather than being proprietary to a specific manufacturer.
Both bulbs share the T10 miniature wedge form factor, a small, wedge-shaped base design that seats without a separate socket locking mechanism.
Both bulbs operate on a 12-volt system, consistent with standard automotive electrical architecture.
Although the 194 and 168 share the same T10 wedge base, they are not interchangeable. The 194 draws 3.78 watts while the 168 draws 4.9 watts, a difference that affects light output and circuit load.
The higher wattage of the 168 rear side marker bulb means it produces more heat and draws more current than the 194 used at the front, which is a relevant consideration when substituting LED or other alternative bulb types.
The front side marker specification for the Saturn Sky remains consistent at the 194 bulb across all four model years covered, 2007-2010.
The rear side marker specification similarly holds constant at the 168 bulb for the full 2007-2010 production span of the Saturn Sky.
