Nissan 720 front and rear side marker bulbs utilize 194 and 67 bulb sizes for optimal illumination. The replacement chart covers 1980 to 1986 model years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Nissan 720 front side marker positions use two distinct bulb types across the model's production years: the 194 for 1983-1986 and the 67 for 1980-1982.
The 194 is an ANSI-standard miniature wedge bulb in the T10 form factor, rated at 12V and 3.78W. The T10 designation refers to a tubular glass envelope roughly 10/8 of an inch wide, with a wedge-style base that requires no separate socket retainer.
The 67 is an ANSI-standard single-filament bulb rated at 12V and 8W, fitted with a BA15s bayonet base. The BA15s designation indicates a single-contact bayonet cap with a 15mm base width.
The 67 is described as a lower-wattage variant of the 1156. While the two bulbs share the BA15s bayonet base, their wattage ratings differ, and substituting one for the other may produce incorrect light output or circuit load.
The rear side marker position on the Nissan 720 uses only the 67 bulb, covering the 1980-1982 model years. No rear side marker data is listed for 1983-1986.
The 194 and 67 bulbs are not interchangeable. The 194 uses a wedge base while the 67 uses a BA15s bayonet base, making the two physically incompatible without a socket adapter.
Both the 194 and 67 carry ANSI standardization applicable to the US and Canadian markets, meaning their electrical and physical specifications conform to a defined industry standard rather than a proprietary specification.
The 1980-1982 front and rear side marker positions on the Nissan 720 share the same bulb type, the 67, which means a single bulb part number covers both locations during those years.
