Nissan Pulsar NX front and rear side marker bulbs utilize 194, 67, or 158 size bulbs as specified in the replacement chart. The chart documents bulb size specifications across the 1983 to 1990 production range.
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 three distinct bulb types across its side marker positions for the 1983-1990 model years: the 194, the 67, and the 158.
The 194 and 158 are both T10 miniature wedge bulbs, meaning they share the same physical base form factor despite differing in wattage.
The 194 operates at 3.78W, while the 158 operates at 3W. Although both are T10 wedge types, they are not interchangeable due to this wattage difference and their separate ANSI designations.
The 67 is a single-filament bulb with a BA15s bayonet base, which is a physically different mounting type from the wedge base used by the 194 and 158. It is not cross-compatible with either of those bulb types.
The 67 is rated at 8W, making it notably higher in wattage than both the 194 and 158. It is described as a lower wattage variant of the 1156, which shares the same BA15s bayonet base but draws significantly more power.
All three bulb types conform to ANSI standards applicable in both the United States and Canada, and all are rated at 12V.
For the 1986-1990 model years, the Nissan Pulsar NX uses the 194 bulb in both the front and rear side marker positions.
The 1984 and 1985 model years use the 67 bulb in both front and rear side marker positions, requiring a BA15s bayonet socket rather than a wedge-type socket.
The 1983 model year uses the 158 bulb in both front and rear side marker positions, which, while sharing the T10 wedge form with the 194, carries a distinct ANSI rating and lower wattage.
Because the 67 uses a bayonet base and the 194 and 158 use wedge bases, a socket designed for one group is physically incompatible with bulbs from the other group, regardless of voltage rating.
