The Saturn Outlook side marker utilizes a 194NA bulb size for illumination purposes. Data for 2007 through 2008 provides the specific information regarding the bulb requirements for the vehicle.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Saturn Outlook uses the 194NA bulb for the front side marker position across all model years from 2007-2010.
The 194NA is a T10 miniature wedge bulb rated at 12V and 3.78W, distinguished by its natural amber glass construction, which produces the amber color required for front side marker lighting without relying on a tinted lens.
The rear side marker position across the 2007-2010 Saturn Outlook calls for the 194 bulb, a T10 miniature wedge type also rated at 12V and 3.78W.
Both the 194 and 194NA share the same T10 wedge base, voltage rating, and wattage, making them physically interchangeable in terms of socket fitment.
Despite their physical compatibility, the 194 and 194NA are not functionally interchangeable in all positions on the Saturn Outlook. The front side marker specifically requires the 194NA, as its amber glass provides the color output for that application.
Both bulb types conform to ANSI standards applicable in the United States and Canada, indicating they meet regulated performance and dimensional criteria for those markets.
The T10 wedge base is a common automotive bulb format that seats by friction rather than by a bayonet or screw mechanism, requiring no rotation during installation or removal.
