The Nissan NV1500 side marker utilizes a 12961 bulb size for illumination purposes across various vehicle configurations. Data for the specified component covers a range from 2012 to 2021.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Nissan NV1500 uses two distinct bulb types across its side marker positions: the 194 at the front and the 3157 at the rear.
The 194 bulb is an ANSI-standardized miniature wedge type in the T10 form factor, rated at 12V and 3.78W.
The front side marker of the NV1500 takes the 194 bulb across the full 2012-2021 model year range covered by these specifications.
The 3157 is an ANSI-standardized dual-filament wedge bulb in the T25 form factor, rated at 12V with a 27W main filament and a 7W secondary filament.
The dual-filament design of the 3157 means it supports two brightness levels within a single housing, which is a characteristic relevant to combined marker and stop or turn functions.
The rear side marker of the NV1500 uses the 3157 bulb across the 2012-2020 model year range covered by these specifications.
The T10 and T25 designations refer to the wedge base form factor of each bulb, with T25 being physically larger than T10. The two types are not interchangeable with each other.
Both the 194 and 3157 carry ANSI standardization for the US and Canadian markets, meaning they conform to defined performance and fitment criteria within those regions.
The significant wattage difference between the 194 at 3.78W and the 3157 at up to 27W reflects the different functional demands placed on the front and rear marker positions.
