The Nissan 710 front turn signal requires a 1157 bulb size while the rear turn signal uses a 1156 bulb size. The replacement chart covers 1974 through 1977 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 710 uses the 1157 bulb for the front turn signal across all documented model years, spanning 1974-1977.
The 1157 is a dual-filament bulb, meaning it carries two separate filaments within a single envelope, allowing it to serve two lighting functions from one unit.
It operates on a 12V electrical system and draws 21W on its primary filament and 5W on its secondary filament, reflecting its dual-purpose design.
The 1157 uses a BAY15d bayonet base, a two-pin offset base that physically prevents incorrect installation of a single-filament bulb in its place.
The rear turn signal on the Nissan 710 uses the 1156 bulb across the same 1974-1977 model year range.
The 1156 is a single-filament bulb rated at 12V and 21W, dedicated to one lighting function rather than two.
The 1156 uses a BA15s bayonet base, a single-pin base that is not interchangeable with the BAY15d base of the 1157, despite the two bulbs sharing a similar physical profile.
Both the 1157 and 1156 conform to ANSI standards applicable in the United States and Canada, indicating standardized performance and dimensional specifications for those markets.
Because the 1157 and 1156 share a similar appearance but differ in base pin configuration and filament count, substituting one for the other is not possible without a corresponding socket mismatch.
