Additional Notes

The 1156 is the sole back up light bulb size listed for the Yugo GV across all model years from 1986-1992.
The 1156 is a single-filament bulb, meaning it serves one lighting function rather than sharing a filament for multiple functions such as braking and running light combined.
The 1156 operates at 12 volts and 21 watts, which places it within the standard low-voltage automotive electrical range common to most passenger vehicles of that era.
The 1156 uses a BA15s bayonet base, a single-contact mount where the bulb is inserted and twisted to lock into place.
The 1156 conforms to ANSI standards applicable in the United States and Canada, indicating a standardized specification for physical and electrical properties.
Because the BA15s base is a single-contact bayonet fitting, it is not interchangeable with dual-contact bayonet bases such as the BA15d, despite the similar physical size of the base.
