The INFINITI M30 front and rear side marker bulbs both require a 194 size bulb for proper operation. The replacement chart covers 1990 to 1992 model 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 194 bulb is the sole bulb type listed across all side marker positions on the INFINITI M30, covering both front and rear applications for the 1990-1992 model years.
The 194 is a miniature wedge-base bulb, classified under the T10 form factor, which refers to its tubular shape with a width of 10 millimeters.
The 194 operates at 12 volts with a power draw of 3.78 watts, placing it in the low-wattage range typical of parking and marker lamp applications.
The 194 carries ANSI standardization, meaning its physical and electrical characteristics conform to a defined specification recognized across the United States and Canada.
The wedge base design of the 194 relies on the bulb's glass envelope and wire leads to form the electrical connection, with no separate metal base or bayonet pins involved.
Because the same 194 bulb size is specified for both the front and rear side marker positions on the M30, the two positions share full bulb interchangeability with each other.
