Jeep Grand Wagoneer front and rear side marker bulbs utilize 194NA and 194 bulb sizes respectively. The replacement chart covers vehicle production spanning 1984 to 1993.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 194 bulb is the dominant fitment across the Jeep Grand Wagoneer side marker positions, appearing in both front and rear applications across the majority of model years covered in the specifications.
Both the 194 and 194NA are T10 miniature wedge bulbs rated at 12V and 3.78W, meaning they share identical electrical characteristics and physical form factor.
The 194NA designation indicates a natural amber glass envelope, which produces an amber output from the bulb itself rather than relying on a colored lens to filter a clear light source.
The sole distinction between the 194 and 194NA is the amber glass coating on the 194NA; in all other respects, the two bulbs are electrically and physically equivalent within the T10 wedge format.
The Jeep Grand Wagoneer (1993) front side marker position calls for the 194NA rather than the standard 194, making that model year the only front fitment in the specifications to require the amber-glass variant.
The rear side marker position for the 1993 model year retains the standard 194, meaning the front and rear side marker bulbs for that year are not interchangeable without a color difference in light output.
Both bulbs conform to ANSI standards recognized in the United States and Canada, placing them within a widely standardized classification system for miniature automotive lighting.
The T10 wedge base format requires no separate metal base or bayonet pins; the bulb seats directly into a wedge-style socket, which is a common socket type across many light vehicle platforms.
Front side marker coverage in the specifications runs from 1984 through 1993, while rear side marker coverage begins at 1986, with both positions sharing the 194 fitment for all years except the 1993 front position.
