Additional Notes

The INFINITI FX35 uses the 168 bulb size for the license plate position across the 2003-2012 model years.
The 168 bulb is a miniature wedge type, classified under the T10 form factor, which refers to a tubular bulb body approximately 10mm wide with a wedge-shaped base that seats directly into a socket without a separate metal cap or pins.
The 168 bulb operates at 12 volts with a power draw of 4.9 watts, placing it in the low-wattage range typical of auxiliary lighting positions such as license plate illumination.
The 168 designation follows the ANSI standardization system, meaning the bulb specification is recognized across both the United States and Canada under a shared technical standard.
Because the 168 is an ANSI-standardized T10 wedge bulb, it shares physical and electrical compatibility with several other bulbs in the same family, such as the 194 and 147, though wattage differences among these types can affect brightness and socket load.
The wedge base design of the T10 format means the bulb is retained by the tension of the socket itself rather than by a bayonet lock or screw mechanism, which is a relevant consideration during replacement.
The consistent use of the 168 bulb across all ten model years of the INFINITI FX35 (2003-2012) indicates no change in the license plate lighting specification throughout the vehicle's production run.
