Additional Notes

The Mazda B2200 uses the 1156 bulb for the back up light across all listed model years.
The 1156 is an ANSI-standard bulb recognized in both the United States and Canada, making it a widely available replacement part.
This bulb operates on a 12-volt electrical system and draws 21 watts, which is typical for incandescent reverse lighting applications.
The 1156 is a single-filament bulb, meaning it serves one lighting function rather than combining two, such as stop and tail duties.
It uses a BA15s bayonet base, a single-contact mount that locks into the socket with a twist, distinguishing it from dual-contact variants like the 1157.
The BA15s base is not interchangeable with dual-contact bayonet bases, so substituting a dual-filament bulb such as the 1157 into this socket is not compatible.
The 1156 specification applies to the Mazda B2200 across the 1982-1984 and 1987-1993 model years as listed in these specifications.
