The INFINITI G20 side marker utilizes a 12961 bulb size for the specific lighting components located on the exterior of the vehicle. Data for the specified automotive lighting equipment covers the range from 1995 to 1996.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The INFINITI G20 uses the 194 bulb for both front and rear side marker positions across all model years listed in the specifications, spanning 1991-1996 and 1999-2002.
The 194 is a miniature wedge-base bulb of the T10 type, meaning it seats without a metal base by wedging its wire leads directly into the socket.
The 194 operates at 12 volts with a power draw of 3.78 watts, placing it among the lower-wattage bulbs used in automotive exterior lighting.
The 194 conforms to ANSI standards recognized in both the United States and Canada, indicating a standardized specification for socket fit and electrical output.
Because the front and rear side marker positions on the G20 share the same bulb size, a single bulb type serves both locations on the vehicle.
The T10 wedge form factor is a widely used automotive standard, and several bulb designations beyond the 194 share the same physical base, though wattage and filament ratings can differ between them, making direct substitution dependent on matching the electrical specification.
