The Mazda B2200 front and rear turn signal bulbs utilize either 1156 or 1157 size specifications. The replacement chart covers vehicle production spanning 1982 to 1993.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 1156 and 1157 are the two bulb types specified for turn signal use across all listed model years of the Mazda B2200.
The 1156 is a single-filament bulb operating at 12V and 21W, fitted with a BA15s bayonet base, and conforming to ANSI standards applicable in the US and Canada.
The 1157 is a dual-filament bulb operating at 12V with filaments rated at 21W and 5W respectively, fitted with a BAY15d bayonet base, and also conforming to ANSI standards for the US and Canada.
The BA15s base of the 1156 and the BAY15d base of the 1157 are physically distinct, as the BAY15d features offset locating pins to prevent incorrect installation. The two bulbs are not interchangeable.
For the front turn signal, the Mazda B2200 uses the 1156 across model years 1987-1993 and the 1157 across model years 1982-1984.
For the rear turn signal, the 1157 is specified for model years 1982-1984, and the 1156 is specified for model years 1987-1991 and 1993.
The 1992 rear turn signal position is the sole instance where the front and rear turn signal bulb types differ within the same model year, with the front using the 1156 and the rear using the 1157.
The dual-filament design of the 1157 allows a single bulb to serve two lighting functions simultaneously, such as turn signaling and running light duty, whereas the single-filament 1156 serves only one function per socket.
