The Nissan Pulsar NX brake light utilizes a 1157 bulb size for the specific lighting component located at the rear of the vehicle. Available data for the specified bulb covers the period from 1983 through 1990.
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 the 1157 bulb for brake lights across the 1983-1990 model years.
The 1157 is a dual-filament bulb operating at 12V with a 21W/5W output rating and a BAY15d bayonet base, conforming to ANSI standards used in the US and Canada.
The dual-filament design of the 1157 allows it to serve both a high-intensity brake function and a lower-intensity running light function within a single housing.
The BAY15d base of the 1157 features two offset pins, a physical characteristic that prevents accidental substitution with single-filament bulbs sharing a similar base style.
The Nissan Pulsar NX uses the 1156 bulb specifically for the Center High Mount Stop Light, covering the 1986-1990 model years.
The 1156 is a single-filament bulb rated at 12V and 21W with a BA15s bayonet base, also conforming to ANSI standards used in the US and Canada.
The BA15s base of the 1156 has a single pin, making it physically incompatible with the BAY15d socket used by the 1157, despite both bulbs sharing a similar cylindrical form.
Although the 1157 and 1156 share the same 21W high-intensity filament rating, the 1157 carries an additional 5W filament that the 1156 does not, making the two bulbs non-interchangeable.
