The INFINITI I30 side marker utilizes a 12961 bulb size for the lighting components located on the exterior of the vehicle. Data for the specific lighting requirements covers the range from 2000 to 2001.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The INFINITI I30 uses two distinct bulb types across its side marker positions: the 194 and the 1157, both of which conform to ANSI standards recognized in the United States and Canada.
The 194 is a T10 miniature wedge bulb rated at 12V and 3.78W. Its wedge base design means it is held in place by the socket itself rather than by a separate locking mechanism.
The 1157 is a dual-filament bulb with a BAY15d bayonet base, rated at 12V with a 21W high filament and a 5W low filament. The dual-filament construction allows it to serve two brightness levels within a single housing.
The front side marker position on the INFINITI I30 uses the 194 bulb across all model years covered, spanning 1996-2001.
The rear side marker position on the INFINITI I30 (2000-2001) uses the 194 bulb, which is the same type as the front side marker for those years.
The rear side marker position on the INFINITI I30 (1996-1999) uses the 1157 bulb, which differs from the front side marker bulb for those same years.
Because the front and rear side marker sockets on 1996-1999 models accept different bulb types, the 194 and 1157 are not interchangeable between positions on those vehicles. The wedge base of the 194 and the BAY15d bayonet base of the 1157 are physically incompatible with each other's sockets.
On 2000-2001 models, both the front and rear side marker positions share the 194 specification, meaning the same bulb type is used throughout all side marker locations for those years.
