The Nissan NV3500 side marker utilizes a 12961 bulb size for illumination purposes within the exterior lighting assembly. Data for the specified component covers the range from 2012 to 2018.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Nissan NV3500 uses two distinct bulb types across its side marker positions, with the front and rear positions each requiring a different bulb for the 2012-2020 model years.
The 194 bulb is the specified front side marker bulb for the NV3500 across all listed model years. It is a T10 miniature wedge bulb rated at 12V and 3.78W, conforming to ANSI standards applicable in both the US and Canada.
The T10 form factor of the 194 bulb refers to a tubular wedge-base design approximately 10mm wide, which seats directly into a wedge-style socket without a separate metal base or pins.
At 3.78W, the 194 is a low-wattage bulb, consistent with its role as a passive marker light rather than a high-intensity signaling or illumination source.
The 3157 bulb is the specified rear side marker bulb for the NV3500 across all listed model years. It is a T25 dual-filament wedge bulb rated at 12V with a wattage of 27W on the high filament and 7W on the low filament, also conforming to ANSI standards for the US and Canada.
The dual-filament construction of the 3157 means the bulb contains two separate filaments within a single envelope, allowing it to operate at two different brightness levels depending on which circuit is activated.
The 3157 bulb uses a wedge base with two offset contact points at its base, which physically prevents incorrect installation of single-filament substitutes that lack the second contact.
The front and rear side marker positions on the NV3500 are not interchangeable in terms of bulb fitment. The 194 and 3157 use different base configurations and wattage ratings, making cross-position substitution incompatible.
Both the 194 and 3157 are ANSI-standardized bulb types, meaning their electrical and physical specifications are governed by a common industry standard rather than being proprietary to Nissan or the NV3500.
The consistent use of the 194 for the front and the 3157 for the rear across the entire 2012-2020 production span of the NV3500 indicates no mid-cycle revision to the side marker bulb specifications during that period.
