The Nissan Quest side marker utilizes 12961, 9005, and 3156 bulb sizes depending on the specific version of the vehicle. Available data covers a range from 2004 through 2016 for the specified lighting components.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Nissan Quest uses three distinct bulb sizes across its front and rear side marker positions: the 168, 194, and 7443, each serving different model years and locations.
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 non-identical despite sharing the same T10 wedge form factor.
The 7443 is a T20 dual-filament wedge bulb rated at 12V with a 21W/5W output, a physically larger and electrically distinct format compared to the T10 bulbs used elsewhere in the Quest's side marker system.
All three bulb types conform to ANSI standards recognized in both the United States and Canada.
The Nissan Quest (2011-2017) uses the 168 bulb for the front side marker position across all seven of those model years.
The 1993-2002 Quest models use the 194 bulb for the front side marker, representing a consistent fitment across that entire production span.
A bulb change occurs in the rear side marker position between the 1999 and 2000 model years. The 1993-1999 Quest uses the 194, while the 2000-2002 Quest uses the 168 in that same position.
The 2011-2017 Quest rear side marker position uses the 7443, a dual-filament T20 bulb, which is a different socket type than the T10 wedge bulbs used in earlier generations. The two formats are not interchangeable.
Because the T10 and T20 wedge bases differ in physical size and pin configuration, substituting a 168 or 194 for a 7443, or vice versa, is not compatible regardless of voltage similarity.
Although the 168 and 194 share the T10 wedge base, their wattage difference means a direct substitution between the two may affect circuit load and luminous output in applications where the original rating is specified.
