The INFINITI QX70 side marker utilizes a 12961 bulb size for the lighting components located on the exterior of the vehicle. Data for the specific bulb requirements covers the period from 2014 through 2017.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The INFINITI QX70 uses the 168 bulb in both the front and rear side marker positions across the 2014-2017 model years.
The 168 is a miniature wedge-base bulb of the T10 type, operating at 12 volts with a power draw of 4.9 watts.
The T10 wedge base is a push-in connector style that requires no socket rotation during installation or removal, relying on friction between the bulb base and the socket housing to maintain contact.
The 168 designation follows ANSI standardization, meaning the bulb conforms to a defined specification recognized across the United States and Canada.
Because the same bulb size applies to all four model years in both the front and rear positions, a single 168 bulb serves all side marker locations on the QX70 without positional distinction.
The T10 form factor is shared by several bulb numbers, including the 194 and 147, which differ in wattage. The 168 at 4.9W falls between the 194 at 3.8W and some higher-output T10 variants, making wattage verification relevant when substituting one T10 bulb for another.
At 4.9 watts on a 12-volt circuit, the 168 draws approximately 0.41 amperes, a figure relevant when replacing the original incandescent unit with an LED alternative, as LED replacements alter the current draw and may affect load-dependent circuits such as hyperflash detection systems.
