Lincoln Mark VIII front and rear side marker bulbs utilize 168, 194, and 916 bulb sizes depending on location and model configuration. The replacement chart covers 1993 to 1998 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 Lincoln Mark VIII uses three distinct bulb types across its front and rear side marker positions: the 168, 194, and 916.
The 168 and 194 are both T10 miniature wedge bulbs operating at 12V, though they differ in wattage. The 168 draws 4.9W while the 194 draws 3.78W, making them electrically incompatible as direct substitutes despite sharing the same physical base type.
The 916 is a T15 wedge bulb rated at 12V and 18W, a notably higher wattage than either the 168 or 194, and its larger T15 base distinguishes it physically from the T10 fitments used elsewhere on the same vehicle.
All three bulb types conform to ANSI standards applicable in both the United States and Canada.
For the Lincoln Mark VIII (1993-1996), the front side marker position takes a 194 bulb, while the 1997-1998 model years use a 168 in that same position.
The rear side marker position on the 1993-1996 Mark VIII uses the 916, a T15 bulb, whereas the 1997-1998 model years use the 168, a T10 bulb. These two bulb types are not interchangeable due to differences in both base size and wattage.
The 1997-1998 Mark VIII is the only configuration in which the front and rear side marker positions share the same bulb type, both using the 168.
