Additional Notes

The Dodge Mirada uses the 1156 bulb for the back up light across all documented model years, spanning 1980-1983.
The 1156 is a single-filament bulb, meaning it serves one lighting function only, which in this application is the back up light.
The 1156 operates at 12 volts and 21 watts, placing it within the standard range for incandescent automotive reverse lighting.
The 1156 is built on a BA15s bayonet base, a single-contact mount where the "s" denotes a single pin, distinguishing it from double-contact bayonet variants.
The 1156 carries ANSI standardization, indicating the bulb conforms to established dimensional and electrical specifications recognized across the United States and Canada.
Because the BA15s base is a single-contact design, it is not interchangeable with the BA15d base, which uses two pins and is found on dual-filament bulbs such as the 1157.
