Additional Notes

The Hino SG23 license plate bulb specifications cover the 1987-1992 model years, with two distinct bulb types used across that span.
The bulb 67 is an ANSI-standardized single-filament type rated at 12V and 8W, fitted with a BA15s bayonet base, and is the specified license plate bulb for the Hino SG23 from 1989-1992.
The BA15s base designation indicates a single-contact bayonet mount, which is not interchangeable with dual-contact bayonet bases without modification.
The bulb 67 is a lower-wattage variant of the 1156 bulb. Despite sharing the same BA15s base, the difference in wattage means the two are not direct equivalents for all applications.
The 1157 is an ANSI-standardized dual-filament bulb rated at 12V with a 21W/5W output, fitted with a BAY15d bayonet base, and is the specified license plate bulb for the Hino SG23 in 1987-1988.
The BAY15d base on the 1157 features offset pins to prevent incorrect insertion, a physical characteristic that distinguishes it from the BA15s base used by the 67 bulb.
The BA15s and BAY15d bases are physically incompatible with each other, meaning the 67 and 1157 bulbs are not interchangeable across the two fitment periods of the SG23.
