Nissan B210 front turn signal bulbs use 1157 size while rear turn signal bulbs use 1156 size. The replacement chart covers 1973 to 1978 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 B210 uses the 1157 bulb for the front turn signal across all model years covered in the specifications, spanning 1973-1978.
The 1157 is a dual-filament bulb, meaning it carries two separate filaments within a single envelope, allowing it to serve two lighting functions at different wattages.
The 1157 operates at 12 volts with a wattage rating of 21W on its primary filament and 5W on its secondary filament, conforming to the ANSI standard recognized in the United States and Canada.
The 1157 uses a BAY15d bayonet base, a two-pin offset base design that prevents incorrect insertion by positioning its two pins at different heights.
The rear turn signal on the Nissan B210 uses the 1156 bulb across the same 1973-1978 model year range.
The 1156 is a single-filament bulb rated at 12 volts and 21W, also conforming to the ANSI standard for the United States and Canada.
The 1156 uses a BA15s bayonet base, a single-pin base that differs structurally from the BAY15d base of the 1157, making the two bulbs non-interchangeable despite their similar physical size.
The difference in base type between the 1157 and 1156 serves as a mechanical safeguard, as installing a single-filament bulb in a dual-filament socket or vice versa would result in incorrect lighting operation.
