The INFINITI I35 side marker utilizes a 12961 bulb size for illumination purposes across the specific lighting assembly. Data for the specified component covers the range from 2002 through 2004.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The INFINITI I35 uses the 194 bulb for both front and rear side markers across all three model years covered in the specifications, 2002-2004.
The 194 is a miniature wedge bulb, classified under the T10 form factor, which refers to its tubular shape with a width of 10 millimeters.
The wedge base design means the bulb is held in place by the socket gripping its base directly, with no separate metal pins or bayonet fittings involved.
The 194 bulb operates at 12 volts and draws 3.78 watts, placing it in the low-wattage range typical of parking and marker lighting applications.
The 194 carries an ANSI designation, meaning it conforms to a standardized specification recognized in both the United States and Canada.
Because the same 194 bulb size applies to both the front and rear side marker positions on the INFINITI I35, a single bulb type serves all four side marker sockets on the vehicle.
The T10 wedge format is shared by several bulb numbers beyond the 194, and not all T10 bulbs are electrically identical, so voltage and wattage ratings remain relevant when selecting a replacement.
