The Nissan NV2500 side marker utilizes a 12961 bulb size for illumination purposes within the lighting assembly. Data provided for the specific component covers the time range from 2012 through 2021.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Nissan NV2500 uses two distinct bulb types across its front and rear side marker positions, with each position drawing from a single consistent specification across all listed model years.
The front side marker on the NV2500 uses the 194 bulb across the 2012-2021 model years.
The 194 is a T10 miniature wedge bulb rated at 12V and 3.78W, conforming to ANSI standards applicable in both the United States and Canada.
The T10 wedge form factor of the 194 bulb means it seats without a separate base, relying on the wedge-shaped glass envelope to make contact within the socket.
The rear side marker on the NV2500 uses the 3157 bulb across the 2012-2020 model years.
The 3157 is a T25 dual-filament wedge bulb rated at 12V with a wattage of 27W on its high-intensity filament and 7W on its low-intensity filament, also conforming to ANSI standards for the United States and Canada.
The dual-filament design of the 3157 allows it to serve two lighting functions within a single housing, with each filament activated independently depending on the circuit signal.
The 194 and 3157 are not interchangeable with each other, as they differ in physical size, wattage, filament count, and socket type.
When substituting LED equivalents for either position, the T10 designation applies to the 194 socket and the T25 designation applies to the 3157 socket, and the replacement must match the respective form factor to seat correctly.
The 3157 rear side marker socket on the NV2500 carries a dual-filament circuit, so a single-filament replacement bulb would not fully serve both functions of that position.
