The Nissan NV1500 front turn signal uses a 3157 or 3157NA bulb size, while the rear turn signal requires a 3156NA bulb size. The replacement bulb chart covers 2012 through 2021 model years.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Nissan NV1500 front turn signal uses the 3157NA bulb for the 2012-2020 model years, while the 2021 model year uses the 3157 bulb instead.
The 3157NA is a dual-filament T25 wedge bulb rated at 12V with a 27W high filament and a 7W low filament, featuring natural amber glass.
The natural amber glass of the 3157NA produces an amber-colored output without relying on a colored lens, which is a common design approach in turn signal assemblies that use clear or white housings.
The 3157 used in the 2021 front turn signal position shares the same T25 wedge base, dual-filament design, and 12V/27W/7W rating as the 3157NA, but its glass envelope is clear rather than amber-tinted.
Because the 3157 and 3157NA share the same base type and electrical ratings, they are physically interchangeable, though the amber tint of the 3157NA affects light color output in ways the 3157 does not replicate on its own.
The Nissan NV1500 rear turn signal uses the 3156NA across all model years from 2012-2021.
The 3156NA is a single-filament T25 wedge bulb rated at 12V and 27W with natural amber glass, distinguishing it from the dual-filament front turn signal bulbs used on the same vehicle.
The single-filament design of the 3156NA means it operates at one fixed output level, unlike the dual-filament 3157 and 3157NA which support two brightness levels for combined stop and turn signal functions.
All three bulb types listed in the specifications conform to ANSI standards applicable in both the United States and Canada, placing them within a standardized sizing and performance framework.
The T25 wedge base is shared across the 3157, 3157NA, and 3156NA bulbs, though the filament count differs between the front and rear positions, making substitution between front and rear bulbs electrically incompatible despite the shared base format.
