Additional Notes

The 1156 is the bulb type specified for the back up light on the Hino FE17 across the 1989-1991 model years.
The 1156 is an ANSI-standard bulb recognized in both the United States and Canada, making it a widely available replacement type in North American markets.
The 1156 is a single-filament bulb, meaning it serves one lighting function only, which is consistent with its dedicated use as a back up light.
The 1156 operates at 12 volts and draws 21 watts, placing it in the standard low-voltage automotive range typical of vehicle electrical systems of that era.
The 1156 uses a BA15s bayonet base, a single-contact bayonet mount that requires alignment with one pin during installation.
The BA15s base is not interchangeable with the BA15d base, which carries two contact pins. Substituting a dual-contact bulb in a single-contact socket is not compatible with this fitment.
