Nissan F10 front turn signal bulbs measure 1157 in size, while rear turn signal bulbs measure 1156 in size. The replacement chart covers vehicle production spanning 1976 to 1978 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 F10 uses the 1157 bulb for the front turn signal across the 1976-1978 model years.
The 1157 is a dual-filament bulb rated at 12V with a 21W/5W output, meaning it carries one filament for the higher-intensity turn signal function and a second for a lower-intensity running or parking light function.
The 1157 uses a BAY15d bayonet base, which features two offset pins at different heights to prevent incorrect installation of the bulb into the socket.
The rear turn signal on the Nissan F10 uses the 1156 bulb across the 1976-1978 model years.
The 1156 is a single-filament bulb rated at 12V and 21W, dedicated solely to one lighting function, which in this position is the turn signal.
The 1156 uses a BA15s bayonet base, which has two pins at equal heights, distinguishing it physically from the BAY15d base of the 1157.
Although the 1157 and 1156 share a similar physical profile and both follow ANSI standards for the US and Canadian markets, their bases are not interchangeable due to the difference in pin alignment between BAY15d and BA15s.
Both bulb types are governed by ANSI standards, indicating standardized electrical and physical tolerances applicable across multiple vehicle manufacturers in North American markets.
