Nissan NV3500 front turn signal uses 3157NA bulb size while rear turn signal uses 3156NA bulb size. The replacement bulb chart covers 2012 to 2020 production years.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Nissan NV3500 uses the 3157NA bulb for the front turn signal across all model years from 2012-2020.
The 3157NA is a dual-filament wedge bulb operating at 12V with a 27W high filament and a 7W low filament, which allows it to serve two lighting functions within a single housing.
The rear turn signal on the NV3500 uses the 3156NA bulb across all model years from 2012-2020.
The 3156NA is a single-filament wedge bulb rated at 12V and 27W, dedicated solely to the turn signal function rather than a combined role.
Both the 3157NA and 3156NA are classified under the ANSI standard, meaning they conform to a standardized specification recognized in the United States and Canada.
Both bulbs belong to the T25 wedge form factor, a designation that refers to the physical base style used for installation and retention in the socket.
The natural amber glass construction of both bulbs produces the amber turn signal color directly through the glass rather than relying on a colored lens or housing to filter a clear bulb.
Although the 3157NA and 3156NA share the same T25 base and natural amber glass, the 3157NA has a dual-filament design while the 3156NA has a single filament, making them non-interchangeable despite their physical similarities.
