Additional Notes

The 1156 is the bulb type specified for the Hino GC17 backup light across the 1990-1991 model years.
The 1156 follows the ANSI standard, making it a recognized specification within the United States and Canada.
It is a single-filament bulb, meaning it serves one lighting function rather than sharing a filament for multiple purposes such as braking and running light combined.
The 1156 uses a BA15s bayonet base, which is a single-contact bayonet mount with a 15mm base width.
The bulb operates at 12 volts and draws 21 watts, consistent with standard automotive electrical systems of that era.
