Nissan Pulsar NX front turn signal bulbs use either 1157 or 1156 size, while rear turn signal bulbs require 1156 size. The replacement chart covers 1983 to 1990 production 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 Nissan Pulsar NX uses two bulb types across its turn signal positions: the 1157 and the 1156, both of which are ANSI-standardized bulbs common in the US and Canadian markets.
The 1156 is a single-filament bulb rated at 12V and 21W, fitted with a BA15s bayonet base. Its single filament means it serves one lighting function only, making it suitable for dedicated turn signal or reverse light applications.
The 1157 is a dual-filament bulb rated at 12V with filaments drawing 21W and 5W respectively, fitted with a BAY15d bayonet base. The two filaments allow it to serve two separate lighting functions within a single housing.
The BA15s base of the 1156 and the BAY15d base of the 1157 are not interchangeable. The BAY15d base has two offset pins that prevent incorrect installation, while the BA15s base has a single pin, meaning the two bulbs cannot be substituted for one another without a socket adapter.
For the Nissan Pulsar NX front turn signal, the 1156 single-filament bulb was specified for the 1983-1985 model years.
The front turn signal specification shifted to the dual-filament 1157 for the 1986-1990 model years, representing a different socket type from the earlier configuration.
The rear turn signal of the Nissan Pulsar NX uses the 1156 single-filament bulb consistently across all listed model years, spanning 1983-1990.
Because the front turn signal socket changed between the 1985 and 1986 model years, a bulb sourced for a 1983-1985 front position is not a direct fit for a 1986-1990 front position, and vice versa.
The rear turn signal socket remained uniform across the entire 1983-1990 production span, meaning rear bulbs are interchangeable across all listed model years for this vehicle.
From 1986-1990, the front and rear turn signal positions on the Pulsar NX use different bulb types, with the front requiring the dual-filament 1157 and the rear requiring the single-filament 1156.
