The INFINITI G35 side marker utilizes a 12961 bulb size for illumination across the specific lighting components found on the exterior of the vehicle. Data for the specified lighting component covers the range from 2003 to 2005.
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 specified for the INFINITI G35 across all side marker positions for the 2003-2005 model years.
The 194 bulb follows the ANSI standard recognized in both the United States and Canada, placing it within a regulated specification framework for miniature automotive lighting.
It belongs to the T10 wedge form factor, a miniature wedge base design that seats without a twist or locking mechanism, relying instead on socket tension to hold the bulb in place.
The 194 operates at 12 volts, consistent with the standard electrical architecture of passenger vehicles in this era.
Its rated wattage of 3.78W classifies it as a low-draw bulb, typical of side marker applications where continuous illumination is expected without significant load on the vehicle's electrical system.
The front and rear side marker positions on the G35 (2003-2005) share the same 194 bulb specification, meaning a single bulb type serves both locations on the vehicle.
Because the T10 wedge base is a widely used form factor, multiple bulb variants from different manufacturers may physically fit the socket; however, electrical compatibility at 12V and approximately 3.78W remains the governing specification for correct function.
