Nissan Pickup front and rear turn signal bulbs utilize 1156NA and 1156 sizes respectively. The replacement chart covers 1995 to 1997 model years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 1156NA and 1156 bulbs share the same ANSI-standardized single-filament design with a BA15s bayonet base, operating at 12 volts and 21 watts.
The BA15s bayonet base features a single contact pin, which distinguishes it from dual-contact bayonet bases used in two-filament bulbs.
The Nissan Pickup (1995-1997) uses the 1156NA for the front turn signal positions across all three model years covered in the specifications.
The rear turn signal positions on the same vehicle use the 1156 across the same 1995-1997 model year range.
The 1156NA differs from the standard 1156 in that its glass envelope is tinted natural amber, which produces an amber output without relying solely on an amber lens.
Because the 1156NA and 1156 share identical base types and electrical ratings, the two bulbs are physically interchangeable in terms of fitment, though the amber tint of the 1156NA affects light color output.
Substituting a clear 1156 in a front turn signal position designed for the 1156NA may alter the color output at the lens, depending on whether the housing uses a clear or amber lens.
At 21 watts, both bulb types fall within the standard wattage range for incandescent automotive turn signal applications, which is relevant when assessing compatibility with load-sensitive flasher relay units.
