The Nissan 310 front turn signal requires a 1157 bulb size while the rear turn signal uses a 1156 bulb size. The replacement chart covers 1979 to 1982 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 Nissan 310 uses the 1157 bulb for the front turn signal across all documented model years, spanning 1979-1982.
The 1157 is a dual-filament bulb rated at 12V with a 21W/5W output, meaning it carries two separate filaments operating at different wattages within a single housing.
It uses a BAY15d bayonet base, a two-pin offset base that prevents incorrect installation by ensuring only one rotational orientation fits the socket.
The rear turn signal on the Nissan 310 uses the 1156 bulb across the same 1979-1982 model year range.
Unlike the 1157, the 1156 is a single-filament bulb rated at 12V and 21W, designed to perform one switching function rather than serving a combined role.
The 1156 uses a BA15s bayonet base, a single-pin base that is not interchangeable with the BAY15d base found on the 1157, despite both belonging to the BA15 bayonet family.
Both the 1157 and 1156 are ANSI-standardized bulbs recognized across the United States and Canada, indicating consistent availability within North American markets.
The front and rear turn signals on the Nissan 310 use different bulb types, and substituting one for the other is not supported by the fitment specifications due to differing base configurations and filament counts.
