Additional Notes

The 1156 is the sole bulb type listed for the Hino SG3323 back up light across the 1993-1995 model years.
The 1156 is an ANSI-standardized bulb recognized in both the United States and Canada, meaning it conforms to a defined set of electrical and physical parameters shared across those markets.
It operates on a 12-volt circuit and draws 21 watts, which is typical of incandescent single-filament automotive bulbs used in back up light applications.
The 1156 uses a BA15s bayonet base, a single-contact fitting where the "s" denotes a single pin, distinguishing it from double-contact bayonet variants such as the BA15d.
Because the 1156 is single-filament, it serves only one lighting function per socket, which is consistent with its dedicated back up light role on the Hino SG3323.
The BA15s base type is a widely produced standard, meaning the 1156 is broadly available as a direct-fit replacement across automotive supply channels.
A common interchangeability consideration with bayonet-base bulbs is confirming that the pin spacing and base collar width match the socket, as visually similar bases with different contact configurations are not interchangeable.
